Streamline Checkpoint Version Mirroring with refs.Primary

Claude Code·pfleidi·3mo ago·50hr·16 Checkpoints·116 file changes·+1237/-843·2.1M tokens

Using the brainstorming skill, I'd like to streamline the way checkpoints version v1 and v1.1 are being mirrored:

  • I'd like to be able to configure reads and writes such that it'll be easy to swap around what is the primary and what is the secondary ref. Right now the primary is v1 but down the road, I'd like to write directly to v1.1 and then mirror to v1.
  • Eventually I'd like to easily be able to turn off mirroring and switch between the v1 and v1.1 implementations based on the checkpoints_version setting
  • Right now, the places where we decide which ref to write to and read from are kinda scattered across the codebase and I'd like to unify and simplify this a much as possible
  • I'd like to start pushing v1.1 to the configured git remote as well and would like everything to be set up to make this job as straightforward as possible

Can you do a thorough pass and look at the codebase with fresh eyes to figure out where we're mirroring between v1 and v1.1 and figure out what changes we can make today to simplify the rollout.

Brainstorming Ideas Into Designs

Help turn ideas into fully formed designs and specs through natural collaborative dialogue.

Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.

<HARD-GATE> Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity. </HARD-GATE>

Anti-Pattern: "This Is Too Simple To Need A Design"

Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.

Checklist

You MUST create a task for each of these items and complete them in order:

  1. Explore project context — check files, docs, recent commits
  2. Offer visual companion (if topic will involve visual questions) — this is its own message, not combined with a clarifying question. See the Visual Companion section below.
  3. Ask clarifying questions — one at a time, understand purpose/constraints/success criteria
  4. Propose 2-3 approaches — with trade-offs and your recommendation
  5. Present design — in sections scaled to their complexity, get user approval after each section
  6. Write design doc — save to docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md and commit
  7. Spec self-review — quick inline check for placeholders, contradictions, ambiguity, scope (see below)
  8. User reviews written spec — ask user to review the spec file before proceeding
  9. Transition to implementation — invoke writing-plans skill to create implementation plan

Process Flow

The terminal state is invoking writing-plans. Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.

The Process

Understanding the idea:

  • Check out the current project state first (files, docs, recent commits)
  • Before asking detailed questions, assess scope: if the request describes multiple independent subsystems (e.g., "build a platform with chat, file storage, billing, and analytics"), flag this immediately. Don't spend questions refining details of a project that needs to be decomposed first.
  • If the project is too large for a single spec, help the user decompose into sub-projects: what are the independent pieces, how do they relate, what order should they be built? Then brainstorm the first sub-project through the normal design flow. Each sub-project gets its own spec → plan → implementation cycle.
  • For appropriately-scoped projects, ask questions one at a time to refine the idea
  • Prefer multiple choice questions when possible, but open-ended is fine too
  • Only one question per message - if a topic needs more exploration, break it into multiple questions
  • Focus on understanding: purpose, constraints, success criteria

Exploring approaches:

  • Propose 2-3 different approaches with trade-offs
  • Present options conversationally with your recommendation and reasoning
  • Lead with your recommended option and explain why

Presenting the design:

  • Once you believe you understand what you're building, present the design
  • Scale each section to its complexity: a few sentences if straightforward, up to 200-300 words if nuanced
  • Ask after each section whether it looks right so far
  • Cover: architecture, components, data flow, error handling, testing
  • Be ready to go back and clarify if something doesn't make sense

Design for isolation and clarity:

  • Break the system into smaller units that each have one clear purpose, communicate through well-defined interfaces, and can be understood and tested independently
  • For each unit, you should be able to answer: what does it do, how do you use it, and what does it depend on?
  • Can someone understand what a unit does without reading its internals? Can you change the internals without breaking consumers? If not, the boundaries need work.
  • Smaller, well-bounded units are also easier for you to work with - you reason better about code you can hold in context at once, and your edits are more reliable when files are focused. When a file grows large, that's often a signal that it's doing too much.

Working in existing codebases:

  • Explore the current structure before proposing changes. Follow existing patterns.
  • Where existing code has problems that affect the work (e.g., a file that's grown too large, unclear boundaries, tangled responsibilities), include targeted improvements as part of the design - the way a good developer improves code they're working in.
  • Don't propose unrelated refactoring. Stay focused on what serves the current goal.

After the Design

Documentation:

  • Write the validated design (spec) to docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md
    • (User preferences for spec location override this default)
  • Use elements-of-style:writing-clearly-and-concisely skill if available
  • Commit the design document to git

Spec Self-Review: After writing the spec document, look at it with fresh eyes:

  1. Placeholder scan: Any "TBD", "TODO", incomplete sections, or vague requirements? Fix them.
  2. Internal consistency: Do any sections contradict each other? Does the architecture match the feature descriptions?
  3. Scope check: Is this focused enough for a single implementation plan, or does it need decomposition?
  4. Ambiguity check: Could any requirement be interpreted two different ways? If so, pick one and make it explicit.

Fix any issues inline. No need to re-review — just fix and move on.

User Review Gate: After the spec review loop passes, ask the user to review the written spec before proceeding:

"Spec written and committed to <path>. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."

Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.

Implementation:

  • Invoke the writing-plans skill to create a detailed implementation plan
  • Do NOT invoke any other skill. writing-plans is the next step.

Key Principles

  • One question at a time - Don't overwhelm with multiple questions
  • Multiple choice preferred - Easier to answer than open-ended when possible
  • YAGNI ruthlessly - Remove unnecessary features from all designs
  • Explore alternatives - Always propose 2-3 approaches before settling
  • Incremental validation - Present design, get approval before moving on
  • Be flexible - Go back and clarify when something doesn't make sense

Visual Companion

A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.

Offering the companion: When you anticipate that upcoming questions will involve visual content (mockups, layouts, diagrams), offer it once for consent:

"Some of what we're working on might be easier to explain if I can show it to you in a web browser. I can put together mockups, diagrams, comparisons, and other visuals as we go. This feature is still new and can be token-intensive. Want to try it? (Requires opening a local URL)"

This offer MUST be its own message. Do not combine it with clarifying questions, context summaries, or any other content. The message should contain ONLY the offer above and nothing else. Wait for the user's response before continuing. If they decline, proceed with text-only brainstorming.

Per-question decision: Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: would the user understand this better by seeing it than reading it?

  • Use the browser for content that IS visual — mockups, wireframes, layout comparisons, architecture diagrams, side-by-side visual designs
  • Use the terminal for content that is text — requirements questions, conceptual choices, tradeoff lists, A/B/C/D text options, scope decisions

A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.

If they agree to the companion, read the detailed guide before proceeding: skills/brainstorming/visual-companion.md

What would you like to clarify about the settings-shape question? For context, I'm trying to figure out what the user-facing dial looks like — one named-mode string, two independent knobs, or keep the current checkpoints_version: "1.1" switch and let an internal table decide the topology. Tell me what's unclear or which direction you're leaning and I'll re-ask more precisely.

I'm not sure what you were suggesting here. I didn't mention changing the shape of the setting at all. The mirroring is already in place and I would like to streamline the way it's implemented. Can you elaborate what you mean?

Good — CommittedRefs becomes the single object that flows through reads, writes, mirror, push, fetch. Three approaches to do that, with my recommendation first.


Approach A (recommended): CommittedRefs is the single object; GitStore owns it; mirror stays direction-agnostic; future push of v1.1 is a localized one-liner.

What changes:

  • GitStore is constructed with a CommittedRefs (the whole struct) instead of just a read ref. New methods: PrimaryRef(), ReadRef(), MirrorRef(), HasMirror(). The existing "writes intentionally bypass the configured ref" docstring goes away — writes now target s.refs.Primary, since flipping Primary is the whole point.
  • Every write/advance site (committed.go × 5, cleanup.go, metadata_reconcile.go, common.go EnsureMetadataBranch) replaces plumbing.NewBranchReferenceName(paths.MetadataBranchName) with s.PrimaryRef() / refs.Primary.
  • A new strategy-package helper AdvanceCommittedPrimary(ctx, repo, refs, hash) wraps the "SetReference + best-effort mirror" sequence. Used by every non-store site that updates the primary today (push rebase, reconcile, attribution, fetch helpers). Today's ~10 explicit MirrorCommittedMetadataRefBestEffort calls collapse into ~10 AdvanceCommittedPrimary calls, and the standalone best-effort wrapper goes away for these call sites (it can stay for cleanup paths like attach where the write goes through the store and the mirror is a separate call).
  • CommittedRefs gains a tiny addition: a PushTarget field that names which ref(s) to push. Today: [refs.Primary] (only v1). When you flip to push v1.1 too, it becomes [refs.Primary, refs.Mirror]. PrePush and fetchAndRebaseSessionsCommon iterate over PushTarget and use generic refspecs (+<ref>:<ref>) rather than refs/heads/<name>:refs/heads/<name>. Non-branch refspecs work the same in git; no remote-tracking ref is created, and the "has unpushed" optimization just falls through to letting git decide.
  • resume.go's "Primary is the v1 branch" comparisons get a clearer name: refs.PrimaryFetchableFromOrigin() — a property on CommittedRefs. Today only the v1 branch has an refs/remotes/origin/... shadow, so this returns true iff Primary.IsBranch(). When v1.1 push happens later, this becomes a PushTarget lookup. The "bootstrap exception" comment in CLAUDE.md gets folded into one method, not scattered across resume/attach/doctor.
  • mirrorSyncedMetadataBranch's Primary.IsBranch() guard goes away: it now uses CommittedRefs directly. The branch-name match check stays as a sanity gate but moves into the method.

Trade-off: most code change of the three, but it's mostly mechanical (literal substitutions) and the result is a single chokepoint. Flipping Primary in the future is exactly a one-line resolver change. Adding v1.1 push is exactly editing the PushTarget field. Turning off mirroring (v1.1-only mode) is Mirror = "" in the resolver and existing HasMirror() guards do their job.

Approach B: typed MetadataRef roles.

CommittedRefs becomes map[Role]MetadataRef, where role ∈ {primary, mirror}, each with Ref, Pushable, RemoteTracked. Operations iterate roles. Maximally general — supports N mirrors, mixed branch/non-branch, etc.

Trade-off: overshoots. The reality is you'll have at most one mirror at a time, and the rollout phases are well-defined. The generality adds indirection without paying for itself.

Approach C: minimal unify (literal swap).

Replace paths.MetadataBranchName with refs.Primary.Short() (and the ref version) wherever Primary is a branch. Don't change GitStore's constructor. Don't add push of v1.1 plumbing. Leave the "writes bypass the configured ref" property in place; just sub the literal for refs.Primary.

Trade-off: smallest diff. Works today because Primary is always a branch. But Primary becoming a non-branch ref in the future (after the flip) breaks refs.Primary.Short() and IsBranch() assumptions everywhere — you'd have to do most of approach A then. So it's a half-step you'll repeat.


My recommendation is A. It pays the refactor cost once, against a clear interface, while the call sites are already churning. Want me to walk through the design in sections, starting with the proposed CommittedRefs/GitStore shape?

Let's do A

3mo ago·36.4s

Five sections coming. Section 1 first — the new shape of CommittedRefs and GitStore.


Section 1 — Data model

CommittedRefs (in cmd/entire/cli/checkpoint/committed_refs.go)

Resolver stays a pure function of EntireSettings:

PrimaryFetchableFromOrigin() is what resume.go and attach.go test instead of == paths.MetadataBranchName. Today it's true iff Primary == v1Branch (because that's the only ref pushed and remote-tracked). When v1.1-push is enabled later, the resolver will mark v1.1 as well.

GitStore (in cmd/entire/cli/checkpoint/store.go)

Constructor changes from NewGitStore(repo) / NewGitStoreWithRef(repo, readRef) / NewCommittedReadStore(ctx, repo) to a single NewGitStore(repo, refs). The "v1 always, no mirror" default is just NewGitStore(repo, ResolveCommittedRefs(ctx)) at the construction site. Two constructors collapse into one.

The existing docstring "Writes intentionally do NOT use this ref" is removed. Writes now target s.refs.Primary. Reads use s.refs.Read. The store is the single chokepoint.

Where each field is consulted (after the refactor)

FieldUsed by
Primaryevery write (WriteCommitted, UpdateCommitted, UpdateSummary, …), EnsureMetadataBranch, metadata_reconcile, cleanup, fetch*MetadataBranch, mirror source
ReadgetSessionsBranchTree, getCheckpointAuthorFromRef, every reader
MirrorMirrorCommittedMetadataRef only
PushPrePush, fetchAndRebaseSessionsCommon, pushBranchIfNeeded

paths.MetadataBranchName and paths.MetadataRefName continue to exist as the source-of-truth string constants, but the only consumers are the resolver and a handful of test/diagnostic call sites (doctor, integration tests inspecting branch contents).


Does this section look right? Specifically:

  • Is Push as a []plumbing.ReferenceName the right shape, or would you rather it be a single ref + an explicit "also push mirror" bool?
  • OK to collapse NewGitStore/NewGitStoreWithRef/NewCommittedReadStore into one constructor that takes CommittedRefs?

Could you investigate if removing Read and only using Primary and Mirror instead would simplify things? Can you identify the trade-offs of such a change?

3mo ago·1m

Good question. Let me trace what Read does in each phase and see if any rule covers all of them.

The three phases and what reads need to do:

PhasePrimaryMirrorReadRead = ?
Today, no opt-inv1""v1Primary
Today, "1.1" opt-inv1v1.1v1.1Mirror
Future flipv1.1v1v1.1Primary
Finalv1.1""v1.1Primary

Today's "1.1" mode is the only row where Read ≠ Primary. That's the whole purpose of the current opt-in: dual-write to v1+v1.1, exercise reads against v1.1 so the new ref is validated in production before the write-target flip. It's the canary phase.

Candidate rules and where they fail:

RuleToday (no opt)Today ("1.1")Future flipFinal
Read = Primary always✓ v1✗ v1 (want v1.1)✓ v1.1✓ v1.1
Read = Mirror if set else Primary✓ v1✓ v1.1✗ v1 (want v1.1)✓ v1.1
Read = Primary + add ReadFromMirror bool

No simple "derived from Primary/Mirror" rule survives all four rows. The first rule breaks today; the second breaks the future flip.

What it would take to actually kill Read:

Three options, each with a real cost:

  1. Flip the write target now. Make the "1.1" resolver return Primary=v1.1, Mirror=v1 today. Then Read = Primary works everywhere. But this changes which ref every write goes to — exactly the future change you scoped out of this PR. It's also operationally riskier (v1.1 must exist locally for any write to succeed; today v1.1 being missing is best-effort).

  2. Replace Read with ReadFromMirror bool. Same expressivity, one field renamed. Not a simplification — same number of knobs, and the bool's meaning quietly inverts across phases (in canary phase it means "exercise the new ref"; if reused later it'd mean "fall back to the old ref"). Easier to misread than an explicit Read ref.

  3. Drop the read canary. Stop reading from v1.1 even when opted in. Today's "1.1" mode becomes "dual-write only," and v1.1 isn't exercised by readers until the flip flips writes and reads together. Bigger flag-day risk; loses the ability to detect read-side problems before committing to the flip.

Trade-off summary

Keep ReadDrop Read, flip nowDrop Read, ReadFromMirrorDrop Read, no canary
Fields on CommittedRefs4 (P/R/M/Push)3 (P/M/Push)4 (P/M/RFM/Push)3 (P/M/Push)
Behavior change todaynonewrites move to v1.1nonereaders stop using v1.1
Exercises v1.1 reads before flipyesyesyesno
Fits "refactor only, no behavior change"yesnoyesno
Future flip is a resolver changeyes (one map)already doneyes (one map + bool)yes (one map)

My recommendation: keep Read. The split between "where writes go" and "where reads come from" is the canary capability — it's the load-bearing reason for the current opt-in. Removing it is a real design choice (collapsing the canary phase), not a code cleanup. It also conflicts with the "refactor only, v1.1 push later" scope you confirmed.

If you do want to collapse it, option 1 — flip the write target now is the only one I'd actually consider, because the others either remove safety or just rename a knob. But that's the future change pulled forward, not a simplification of today's design.

Want to (a) keep Read and proceed with the section as written, (b) pull the write-target flip into this PR and drop Read, or (c) something else?

Okay. keep read

3mo ago·37.2s

Section 1 stands as written. Moving to section 2.


Section 2 — Call-site refactor (writes, mirror, push, fetch)

Writes route through GitStore.refs.Primary.

In cmd/entire/cli/checkpoint/committed.go, the five plumbing.NewBranchReferenceName(paths.MetadataBranchName) write sites become s.refs.Primary:

  • WriteCommitted (final ref update after building the new commit tree)
  • UpdateSummary (refresh the root metadata.json)
  • UpdateCheckpointSummary (combined attribution path)
  • UpdateCommitted (transcript replace at stop time)
  • ensureSessionsBranch (orphan initialization)

getSessionsBranchTree keeps its current shape but the v1-only fallback (refs/remotes/origin/entire/checkpoints/v1) becomes a property check: it falls back to origin only when refs.PrimaryFetchableFromOrigin() is true and the local ref is missing. The fallback hash is read from refs/remotes/origin/<Primary.Short()>.

One advancement helper replaces ad-hoc SetReference + MirrorBestEffort pairs.

New helper in cmd/entire/cli/strategy:

Call sites that today do SetReference(Primary, hash) followed by MirrorCommittedMetadataRefBestEffort:

  • EnsureMetadataBranch (three paths: from remote, on-fast-forward, on orphan create)
  • metadata_reconcile.ReconcileDisconnectedMetadataBranch (two paths)
  • git_operations.fetchMetadataFromOrigin (after SafelyAdvanceLocalRef)
  • checkpoint_remote.FetchMetadataBranch (after PromoteTmpRefSafely)
  • push_common.mirrorSyncedMetadataBranch (4 fast-forward/rebase paths)
  • cleanup.DeleteOrphanedCheckpoints (orphan removal commit)
  • manual_commit_hooks.persistCombinedAttribution and finalizeTurnTranscripts (post-commit + finalize)
  • manual_commit_condensation (after condensation commit)

MirrorCommittedMetadataRefBestEffort itself stays as the implementation of the mirror step inside AdvanceCommittedPrimary, but the standalone export is removed (no remaining external callers). MirrorCommittedMetadataRef (the strict version) stays exported because attach.go and explain.go GenerateCheckpointSummary use it after writes that go through the store — those two paths want a fatal failure, not best-effort.

mirrorSyncedMetadataBranch's Primary.IsBranch() guard and short-name match guard fold into the helper: if refs.Primary and the synced branch agree, advance; otherwise log-and-skip. The guards stop being a per-site concern.

Push and fetch consult refs.Push and refs.Primary.

PrePush iterates over refs.Push instead of pushing the literal paths.MetadataBranchName. Today Push = [v1Branch] always, so the iteration is a one-element loop. When v1.1 push lands later, the resolver appends v1.1; no call-site change needed.

pushBranchIfNeeded becomes pushRefIfNeeded(ctx, target, ref) and accepts any plumbing.ReferenceName. The refspec changes from +refs/heads/<branch>:refs/heads/<branch> to +<ref>:<ref>. For branch refs this is identical to today; for non-branch refs (future v1.1) it works without remote-tracking. The "has unpushed" optimization stays for branches (consulting refs/remotes/<target>/<branch.Short()>) and is skipped for non-branch refs — git itself handles the no-op case.

fetchAndRebaseSessionsCommon takes refs.Primary instead of a branch name string. Same refspec generalization. The rebase logic doesn't change — it operates on commit graphs, not on ref kind.

fetchMetadataFromOrigin / FetchMetadataBranch (in cmd/entire/cli/strategy/checkpoint_remote.go) already consult refs.Primary for the source ref — they pick up the non-branch generalization "for free" once refs.Primary can legitimately be a non-branch ref.

Resume / attach bootstrap exception, named.

The three sites in resume.go and attach.go that today compare committedReadRef == plumbing.NewBranchReferenceName(paths.MetadataBranchName) become refs.PrimaryFetchableFromOrigin() checks. That method encodes "we have an origin-tracking shadow for Primary; bootstrap from origin is safe." Today it's true iff Primary is the v1 branch. When v1.1 push is enabled later, the resolver will mark v1.1 as fetchable from origin and the same call sites work without modification.

promoteRemoteTrackingMetadataBranch is renamed to promoteRemoteTrackingPrimary and accepts refs.Primary rather than hard-coding paths.MetadataBranchName.

Net effect on paths.MetadataBranchName and paths.MetadataRefName.

After the refactor, the only consumers in production code are:

  • committed_refs.go (the resolver — the one place that maps versions → refs)
  • doctor.go (checkDisconnectedMetadata reports the user-facing branch name in error text)
  • a small number of test/integration assertions that inspect the v1 branch directly

Every other production reference goes through CommittedRefs.


Two checks before I move on:

  1. The split between best-effort and strict mirroring — best-effort folded into AdvanceCommittedPrimary (the common case), strict exported for attach/explain summary-write paths. Does that match what you want, or should both paths converge on best-effort?
  2. Renaming promoteRemoteTrackingMetadataBranchpromoteRemoteTrackingPrimary, pushBranchIfNeededpushRefIfNeeded, fetchAndRebaseSessionsCommon's branchName parameter → ref plumbing.ReferenceName — OK to rename, or prefer to keep the existing names and just generalize the parameters?

The split is fair: attach and explain are user driven commands that aren't used all that often and we'd like to see if something goes wrong there since we can communicate an error state to the user directly compared to hooks that happen without user intervention.

3mo ago·35.5s

Good. I'll take the renames as fine too — section 2 stands. Section 3 next.


Section 3 — Future-flip story

This section describes what changes when each future milestone lands, so we can verify the refactor actually delivers the "one-line flip" property you asked for.

Milestone 1 (this PR): refactor only.

Behavior identical to today. The resolver produces:

  • checkpoints_version unset/"1"Primary=v1, Read=v1, Mirror="", Push=[v1]
  • "1.1"Primary=v1, Read=v1.1, Mirror=v1.1, Push=[v1]

paths.MetadataBranchName and paths.MetadataRefName are touched only by the resolver and a few diagnostic sites.

Milestone 2: push v1.1 to the configured remote (your stated near-term goal).

Single change in the resolver — the "1.1" case becomes:

Plus one change in PrimaryFetchableFromOrigin(): it now returns true when Primary is in Push (the rule today happens to coincide with "is a branch," but the actual semantic is "we push it, so origin tracks it"). No call-site changes.

This works because pushRefIfNeeded and fetchAndRebaseSessionsCommon already accept any plumbing.ReferenceName after section 2. The refspec +refs/entire/checkpoints/v1.1:refs/entire/checkpoints/v1.1 is valid git; the server stores it under refs/entire/... on the remote side; no remote-tracking ref is created locally for it (refs/remotes/origin/refs/entire/... is not standard). That's fine — the "has unpushed" optimization is skipped for non-branch refs and git handles the no-op case.

One real wrinkle worth calling out: today v1.1 mirror failure is logged, not fatal, because the mirror is local-only. Once it's pushed, a stale local v1.1 means a stale push. The mirror-after-write step still runs best-effort, but PrePush should advance the mirror once more before pushing it, so we don't push a stale tip. That's a one-line addition in PrePush (call MirrorCommittedMetadataRef strict, since the user is watching), gated on refs.Mirror != "" and refs.Pushable(refs.Mirror).

Milestone 3: flip the write target (v1.1 becomes Primary).

Resolver:

What this changes in code: nothing outside the resolver. Writes go through s.refs.Primary (now v1.1). The mirror now advances v1 from v1.1. AdvanceCommittedPrimary works direction-agnostically. Push iterates [v1.1, v1].

What this changes operationally:

  • v1.1 must exist locally for any write to succeed (today it's optional). That's a one-time migration concern — on first write under this mode, EnsureMetadataBranch (renamed to EnsurePrimaryRef at this point) creates v1.1 from v1 if v1.1 is missing. Already supported by today's logic for v1; just needs the rename.
  • PrimaryFetchableFromOrigin returns true for v1.1.
  • The "v1 must exist for legacy clients" concern is handled by Mirror=v1 + Push=[..., v1].

Milestone 4: drop v1 entirely.

Resolver:

HasMirror() returns false, so AdvanceCommittedPrimary's mirror step is a no-op. v1 stops being touched. We presumably keep paths.MetadataBranchName as a string constant for doctor cleanup / legacy detection, but no production read/write path references it.

What every milestone shares

Each milestone is a change to the resolver's switch statement plus, in some cases, a one-line PrimaryFetchableFromOrigin() rule update. None of them touches committed.go, push_common.go, metadata_reconcile.go, cleanup.go, resume.go, attach.go, explain.go, git_operations.go, or the hook paths. That's the property you want this refactor to deliver.


Three things to confirm before moving to error handling:

  1. The "pre-push strict re-mirror" step in milestone 2 — only matters once v1.1 is pushed, not part of this PR. Is that scope split OK, or would you rather wire it now so it's already in place?
  2. PrimaryFetchableFromOrigin() semantics as "Primary is in Push" — agrees with your mental model, or do you think of it differently?
  3. Is the migration concern in milestone 3 (auto-create v1.1 from v1 on first write) worth solving via EnsurePrimaryRef, or should that be a separate explicit migration?

Can you summarize this rollout plan into a few bullet points so I can share them with a coworker?

Checkpoints v1/v1.1 mirroring — refactor and rollout

  • This PR (refactor only): unify the v1/v1.1 plumbing behind a single CommittedRefs{Primary, Read, Mirror, Push} struct. GitStore takes it in its constructor; writes go to Primary, reads to Read, mirror advances Mirror, push iterates Push. A new AdvanceCommittedPrimary helper replaces the ~10 scattered SetReference + MirrorBestEffort pairs. Push and fetch generalize to any ref name, not just branches. No behavior change — "1.1" still means Primary=v1, Read=v1.1, Mirror=v1.1, Push=[v1].
  • Next: push v1.1 to the remote. One-line resolver change — append v1.1 to Push. Plus a strict re-mirror step in PrePush so we don't ship a stale tip. No call-site changes.
  • Later: flip the write target to v1.1. Resolver change only — "1.1" becomes Primary=v1.1, Read=v1.1, Mirror=v1, Push=[v1.1, v1]. Writes redirect; the mirror helper runs in the inverse direction with no code change.
  • Eventually: drop v1. Resolver change only — Mirror="", Push=[v1.1]. Existing HasMirror() guards turn the mirror step into a no-op.
  • What the refactor buys us: each future milestone is a change to the resolver's switch statement. No edits to committed.go, push_common.go, metadata_reconcile.go, cleanup.go, resume.go, attach.go, explain.go, git_operations.go, or hooks.
  • What stays explicit, by design: Read is kept separate from Primary because today's "1.1" mode intentionally writes to v1 while exercising reads from v1.1 — that's the canary phase. Collapsing Read would either pull the write-target flip forward or remove the read canary; neither is in scope.
  • Mirror failure policy stays split: best-effort in hooks (silent, logged); strict in attach and explain summary writes, where the user is present and we want to surface errors.

Can you copy the summary to my clipboard?

3mo ago·1m

Copied. Ready for section 4 (error handling and edge cases) whenever you are.

Can you copy the intended rollout plan onlywithout any implementation details? As in what the settings do now vs. in the next steps. Keep it short and just illustrate what I asked you.

3mo ago·24.8s

Copied.

Okay, continue. Please note that this implementation is dependent on another change I'm in the process of making so do whatever you can to capture everything you need to implement this task without actually implementing it since some changes to the codebase will have to ship before starting the implementation. Would a design spec and/or plan help to get going faster?

Tasks accurate. Proceeding with section 4. Section 5 after.


Section 4 — Error handling and edge cases

Mirror failures — confirming the split.

SitePolicyWhy
Post-commit attribution, condensation, finalization, push rebase, cleanup, reconcile, fetch helpers, EnsureMetadataBranchBest-effort (logged, never fails the primary op)All happen inside hooks or autonomous flows; the user isn't watching, and the primary op (the v1 write) already succeeded — failing it because the local-only mirror lagged would be a strict regression
attach, explain --generate-summaryStrict (error returned, primary write is reported as "succeeded but mirror failed")User-driven, foreground commands; surfacing the error is more useful than silent drift

Today's behavior is already this split (section 2). The refactor preserves it: best-effort lives inside AdvanceCommittedPrimary; strict is MirrorCommittedMetadataRef called explicitly by attach and explain after their store write.

Error returned vs. primary-write rollback.

When strict mirror fails, the primary write is not rolled back. The error message follows today's pattern: "checkpoint was written to <Primary>, but failed to mirror to <Mirror>: %w". The user can re-run the command (it's idempotent — same CheckpointID reuses the slot) or run entire doctor (which already detects disconnected metadata; we'd extend it to also notice and re-advance a behind mirror).

Primary missing on mirror attempt.

ErrPrimaryMetadataMissing (already exists) is returned when the primary ref doesn't exist yet. Best-effort wrapper treats it as "expected on first use" and skips. Strict callers (attach, explain) propagate it — but in practice they only call after a successful write through the same store, so primary exists by that point.

Non-branch primary or mirror.

Today this is impossible — Primary is always a branch. Once milestone 2 lands, refs.Mirror = refs/entire/checkpoints/v1.1 will be a non-branch ref that's pushed. Once milestone 3 lands, refs.Primary will be that same non-branch ref. Things that break under naive code:

  • Short() on a non-branch ref returns the full ref name without refs/ (e.g. entire/checkpoints/v1.1) rather than a short branch name. Display strings need to handle this. Practical impact: error messages and progress text ("Pushing entire/checkpoints/v1.1 to origin...") — minor cosmetic difference, not a bug.
  • Remote-tracking refs (refs/remotes/origin/<branch>) don't exist for non-branch refs. The "has unpushed" optimization skips when the ref isn't a branch — falls through to git push, which handles the no-op case server-side. Slightly more network on a no-op push; acceptable.
  • IsBranch() checks in mirrorSyncedMetadataBranch and FetchMetadataBranch need to switch to "is this ref pushable" (via refs.Pushable(...)) — the refactor does this in section 2.
  • go-git's Reference() accepts any plumbing.ReferenceName, including non-branch refs under refs/entire/.... No library-level concern.

Refspec subtleties.

The generalized refspec is +<ref>:<ref>. The leading + is force-push semantics, which is what we want — checkpoint refs are append-only by design but rebase recovery can rewrite history during reconcile. Today's push of v1 already uses +refs/heads/<branch>:refs/heads/<branch>. Same semantics for non-branch refs.

Branch-protection rules on the remote (GH013, rulesets) currently block refs/heads/entire/* rejections. Once we push refs/entire/checkpoints/v1.1, that's outside refs/heads/ and likely outside most existing rulesets — which is good for unblocking pushes but bad if users have a "block all entire/* pushes" rule that only matched refs/heads/. We document this in the rollout notes (milestone 2) but it doesn't change the refactor.

Concurrent writes.

Two processes writing to the same primary ref is already handled by today's fetch-and-rebase recovery in push_common.go. The refactor doesn't change this. The mirror ref is local-only (or, once pushed, a passive copy of primary), so concurrency on the mirror reduces to "two processes might race to update Mirror to the same hash." SetReference is atomic at go-git's level for our purposes; if a later write briefly leaves Mirror behind Primary, the next AdvanceCommittedPrimary corrects it. Worth one short paragraph in the spec, not a code change.

paths.MetadataRefName const naming.

Today the constant is MetadataRefName = "refs/entire/checkpoints/v1.1" — the name suggests "the metadata ref" generically, but it's specifically the v1.1 ref. Once we have multiple non-branch refs (e.g. if a future milestone wires a v1.2), this name reads wrong. Renaming to MetadataRefV11 (and MetadataBranchNameMetadataBranchV1) is a minor cleanup worth doing inside this refactor since we're touching all the consumers anyway. Not strictly required.

Decisions I made for the deferred section 3 questions:

  1. Pre-push strict re-mirror (milestone 2): add it at milestone 2 time, not now. The refactor places PrePush in the right shape for it — iterating refs.Push and calling a hook before push — but the actual strict re-mirror step is a milestone-2 concern. Recording in spec as part of the milestone-2 description.
  2. PrimaryFetchableFromOrigin() semantics: "Primary is in Push" (i.e. we push it, so origin tracks it). Today: equivalent to Primary.IsBranch() because Push only contains the v1 branch. Future-proof without changing today's truth-table.
  3. EnsurePrimaryRef auto-migration (milestone 3): handle inside EnsurePrimaryRef (rename of EnsureMetadataBranch) at milestone-3 time. The existing function already creates the v1 branch from origin or as an orphan when missing; the same logic, parameterized by refs.Primary, handles v1.1. The migration step is "if Primary doesn't exist locally but the previous Primary (v1) does, seed Primary from it." That's a milestone-3 addition, not part of this refactor.

Anything to push back on before section 5 (testing)?

Nope, go ahead

3mo ago·36.7s

Section 5 — Testing strategy

Unit tests — resolver and CommittedRefs.

The resolver is pure (settings → CommittedRefs), so it's the cheapest place to lock in the topology table. Extend committed_refs_test.go:

Casecheckpoints_versionExpected CommittedRefs
Unsetabsent{Primary: v1, Read: v1, Mirror: "", Push: [v1]}
Empty string""same as unset
"1""1"same as unset
"1.1""1.1"{Primary: v1, Read: v1.1, Mirror: v1.1, Push: [v1]}
Numeric 1.1 (rejected)1.1 (float)falls back to unset topology
Bool / unrelatedtrue, "abc"unset topology

Plus a small focused test on each method:

  • HasMirror() true when Mirror != "", false otherwise.
  • PrimaryFetchableFromOrigin() true when Primary ∈ Push, false otherwise. Test both: today's v1-only case (true), and a hand-built struct where Primary is the v1.1 ref but Push is empty (false).
  • Pushable(ref) membership check.

These are pure-function tests — no repo, no fixtures.

Unit tests — GitStore constructor.

Existing committed_read_store_test.go already covers "read ref is honored" with a fixture repo containing both v1 and v1.1 refs. After the refactor:

  • Replace NewGitStoreWithRef(repo, customRef) calls with NewGitStore(repo, refsWithReadAt(customRef)).
  • Add one new test: NewGitStore(repo, refs) writes to refs.Primary (not the v1 literal). Build refs with Primary pointing at a synthetic ref name; call WriteCommitted; assert the ref that advanced is refs.Primary. This is the test that proves the "writes intentionally bypass the configured ref" property is gone.

Unit tests — AdvanceCommittedPrimary.

New helper, new test file. Cases:

  • Mirror = "" → only Primary advances, no mirror write attempted.
  • Mirror = <ref>, Primary exists → both refs end at hash.
  • Mirror = <ref>, Mirror fails to write (e.g. simulated storer error) → Primary still advanced; error logged but not returned (best-effort).
  • Mirror = <ref>, Primary missing at mirror time → returns nil (best-effort skip via ErrPrimaryMetadataMissing).

Existing v1_custom_ref_mirror_test.go already covers the strict MirrorCommittedMetadataRef paths — those stay valid since strict-mode behavior is unchanged.

Unit tests — push/fetch generalization.

Existing push_common_test.go already covers branch-name push/rebase paths. After the refactor, the helpers accept plumbing.ReferenceName directly:

  • Smoke test that pushRefIfNeeded with a non-branch ref (e.g. refs/entire/checkpoints/v1.1) succeeds against a local bare repo. Uses the same bareDir fixture pattern.
  • Smoke test that fetchAndRebaseSessionsCommon accepts a non-branch ref. Skip the "has unpushed" optimization assertion for non-branch refs.

These two tests verify the future v1.1-push wiring works without flipping the resolver. They're the gate that makes milestone 2 a one-liner.

Integration tests — touch as few as possible.

Existing integration tests that pin paths.MetadataBranchName (the bulk of testenv.go, attribution tests, sha256 repo test, deferred finalization, etc.) keep working because Primary is still the v1 branch in every test scenario. The literal paths.MetadataBranchName in test code is fine — it's documenting that today's tests expect writes to the v1 branch. Don't churn them.

The one integration test that actually depends on the v1.1 mirror is TestAttach_MirrorsToV1CustomRefWhenOptedIn. It exercises the strict-mirror failure path through attach. Keep as-is — the strict mirror call is what gets wired to the new store but the assertion is unchanged.

TestMirrorCommittedMetadataRefBestEffort_V1MissingNoOp and the test that exercises mirrorSyncedMetadataBranch after a sync also stay valid — those are the regression guards for milestone 2 and milestone 3.

What I deliberately don't add tests for.

  • Milestone 2/3/4 resolver outputs. Those tests get added when the milestones land, not now. The resolver test today asserts only the four valid checkpoints_version values that exist today. Adding speculative test cases for future values bakes in design decisions that haven't been confirmed and would have to be rewritten.
  • A "swap Primary and Mirror" property test. The refactor's claim is that flipping the resolver doesn't require call-site changes, but verifying that empirically would mean either re-deriving every call site under a synthetic topology (effectively duplicating production code in tests) or running the full integration suite under a forced topology. The honest verification is "milestone 2 lands as a one-line change with no other diff" — that's a code-review property, not a test property.

Edge case I would test if practical, but won't.

Two processes racing to advance the mirror to the same Primary hash. The race window is too narrow for a flake-free test and the consequence is "mirror briefly lags; next write corrects it." Document the behavior in the spec; don't write a test that will be flaky.


That closes the design. Next: write the spec at docs/superpowers/specs/2026-06-03-checkpoints-v1.1-streamline-mirroring-design.md, including my recommended answers for the section 3 deferred questions. Anything to revise in section 5 before I write?

This is the spec for the task that will be implemented before this one: /Users/pfleidi/entire/cli/.worktrees/feat/checkpoints-v1.1-rewind-clean/docs/superpowers/specs/2026-06-03-checkpoints-v1.1-topology-coverage-design.md

Read it and see if our current design needs to be updated

3mo ago·2m

Read it. Most of our design holds; three places need updating.

What the prerequisite changes that we depend on (and should integrate):

  1. GetMetadataBranchTree(repo) is renamed to GetMetadataRefTree(repo, ref). Every caller passes the ref it wants. The prereq inlines paths.MetadataBranchName at five v1-pinned callsites (resume.go × 4, explain.go × 1) and routes the picker through ResolveCommittedRefs(ctx).Read. This is a strictly better starting point than what our spec assumed — we no longer need to invent an explicit-ref helper; it'll already be there.

  2. ListOrphanedSessionStates already uses NewCommittedReadStore(ctx, repo). Our spec's "cleanup write/advance sites" list still applies for the actual deletion write, but the orphan-detection read is already topology-aware. Drop that from our migration list.

  3. Dead code is gone (strategy.ListSessions, GetSession, three private helpers). Doesn't affect our design.

Spec changes I'd make:

A. Update Context. Note that the prerequisite has landed and rename GetMetadataBranchTree references to GetMetadataRefTree(repo, ref) everywhere in our spec.

B. Add the 5 prereq-inlined v1 call sites to our refactor's migration list (section 2, write/fetch path). The prereq deliberately calls these "intentional v1-pinning, not deferred" because at prereq-merge time, v1 is the primary and the durable identifier for fetches — so inlining v1 was correct for the prereq's scope. The prereq explicitly says topology inversion is out of its scope and notes those call sites will move when topology inverts.

Our refactor is the topology-inversion enabler, so the right place to migrate them is here:

  • resume.go × 4 (fetch chain + bootstrap promotion): three become refs.Primary-bound via GetMetadataRefTree(repo, refs.Primary); the fourth (the committedReadRef == v1Branch bootstrap gate) becomes refs.PrimaryFetchableFromOrigin().
  • explain.go × 1 (loadV1MetadataRootTree): becomes GetMetadataRefTree(repo, refs.Primary).

Runtime behavior today is identical — refs.Primary == v1Branch in both v1-only and v1.1-canary modes, so the inlined v1 and refs.Primary resolve to the same value. Zero behavior change at refactor-merge time; milestone 3 (the write-target flip) then automatically picks up the fetch chain.

C. Acknowledge the prereq's accepted trade-off. Cleanup orphan detection can false-flag under v1.1 mirror staleness; the prereq accepted that. Our refactor doesn't change the cleanup write path's mirror policy, so we inherit the same accepted risk without re-litigating it. Worth one sentence in our error-handling section.

D. File-level impact updates:

  • Remove cleanup.go ListOrphanedSessionStates from our touch list (already done by prereq).
  • Add resume.go (× 4 callsite migrations) and explain.go (× 1) to our touch list with their new role: route the fetch chain through refs.Primary.
  • strategy.GetMetadataBranchTree row → renamed to GetMetadataRefTree. Our refactor's use of this helper in getSessionsBranchTree's v1 fallback path picks it up as-is.

E. Testing addition: the prereq adds a v1.1-only-read test for the picker (pre-points v1 backward, points v1.1 at the data). When our refactor lands, the picker's call goes through the new GitStore constructor — that test needs a mechanical update for the new signature. Worth noting in section 5 so the implementation doesn't miss it.

Things that don't change:

  • CommittedRefs{Primary, Read, Mirror, Push} shape.
  • Keep-Read-separate decision.
  • Future-flip story / milestone sequence.
  • Best-effort vs. strict mirror policy split.
  • AdvanceCommittedPrimary helper.
  • Resolver test table.

One genuine open question the prereq surfaces:

The prereq's "v1 is the durable identifier" language is bound to "v1 is what's pushed." Once milestone 2 ships and v1.1 is also pushed, "durable identifier" stops being a single ref. The prereq is internally consistent — but for our spec to be self-contained, we should pick consistent terminology. I'd propose dropping "durable identifier" in favor of "primary" / "what's in refs.Push" so the wording survives the rollout phases.

Want me to apply A–E to the spec and use the simpler terminology, or push back on any of them first?

Yes

Spec written and self-reviewed at docs/superpowers/specs/2026-06-03-checkpoints-v1.1-streamline-mirroring-design.md. Self-review removed the speculative Pushable(ref) public method that had no in-scope caller.

The spec captures:

  • Topology and rollout phase table
  • CommittedRefs.Push + PrimaryFetchableFromOrigin additions
  • GitStore constructor collapse to NewGitStore(repo, refs)
  • AdvanceCommittedPrimary helper and the ~10 callsites it subsumes
  • Push/fetch generalization to any plumbing.ReferenceName
  • The five prereq-inlined v1 callsites migrated to refs.Primary
  • Mirror-policy split kept (best-effort in hooks, strict in attach/explain)
  • Recommended answers (with rationale) for the three deferred questions
  • File-level impact table, testing list, verification per logical step
  • Out-of-scope items mapped to milestones 2/3/4

Writing Plans

Overview

Write comprehensive implementation plans assuming the engineer has zero context for our codebase and questionable taste. Document everything they need to know: which files to touch for each task, code, testing, docs they might need to check, how to test it. Give them the whole plan as bite-sized tasks. DRY. YAGNI. TDD. Frequent commits.

Assume they are a skilled developer, but know almost nothing about our toolset or problem domain. Assume they don't know good test design very well.

Announce at start: "I'm using the writing-plans skill to create the implementation plan."

Context: If working in an isolated worktree, it should have been created via the superpowers:using-git-worktrees skill at execution time.

Save plans to: docs/superpowers/plans/YYYY-MM-DD-<feature-name>.md

  • (User preferences for plan location override this default)

Scope Check

If the spec covers multiple independent subsystems, it should have been broken into sub-project specs during brainstorming. If it wasn't, suggest breaking this into separate plans — one per subsystem. Each plan should produce working, testable software on its own.

File Structure

Before defining tasks, map out which files will be created or modified and what each one is responsible for. This is where decomposition decisions get locked in.

  • Design units with clear boundaries and well-defined interfaces. Each file should have one clear responsibility.
  • You reason best about code you can hold in context at once, and your edits are more reliable when files are focused. Prefer smaller, focused files over large ones that do too much.
  • Files that change together should live together. Split by responsibility, not by technical layer.
  • In existing codebases, follow established patterns. If the codebase uses large files, don't unilaterally restructure - but if a file you're modifying has grown unwieldy, including a split in the plan is reasonable.

This structure informs the task decomposition. Each task should produce self-contained changes that make sense independently.

Bite-Sized Task Granularity

Each step is one action (2-5 minutes):

  • "Write the failing test" - step
  • "Run it to make sure it fails" - step
  • "Implement the minimal code to make the test pass" - step
  • "Run the tests and make sure they pass" - step
  • "Commit" - step

Plan Document Header

Every plan MUST start with this header:

Task Structure

No Placeholders

Every step must contain the actual content an engineer needs. These are plan failures — never write them:

  • "TBD", "TODO", "implement later", "fill in details"
  • "Add appropriate error handling" / "add validation" / "handle edge cases"
  • "Write tests for the above" (without actual test code)
  • "Similar to Task N" (repeat the code — the engineer may be reading tasks out of order)
  • Steps that describe what to do without showing how (code blocks required for code steps)
  • References to types, functions, or methods not defined in any task

Remember

  • Exact file paths always
  • Complete code in every step — if a step changes code, show the code
  • Exact commands with expected output
  • DRY, YAGNI, TDD, frequent commits

Self-Review

After writing the complete plan, look at the spec with fresh eyes and check the plan against it. This is a checklist you run yourself — not a subagent dispatch.

1. Spec coverage: Skim each section/requirement in the spec. Can you point to a task that implements it? List any gaps.

2. Placeholder scan: Search your plan for red flags — any of the patterns from the "No Placeholders" section above. Fix them.

3. Type consistency: Do the types, method signatures, and property names you used in later tasks match what you defined in earlier tasks? A function called clearLayers() in Task 3 but clearFullLayers() in Task 7 is a bug.

If you find issues, fix them inline. No need to re-review — just fix and move on. If you find a spec requirement with no task, add the task.

Execution Handoff

After saving the plan, offer execution choice:

"Plan complete and saved to docs/superpowers/plans/<filename>.md. Two execution options:

1. Subagent-Driven (recommended) - I dispatch a fresh subagent per task, review between tasks, fast iteration

2. Inline Execution - Execute tasks in this session using executing-plans, batch execution with checkpoints

Which approach?"

If Subagent-Driven chosen:

  • REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development
  • Fresh subagent per task + two-stage review

If Inline Execution chosen:

  • REQUIRED SUB-SKILL: Use superpowers:executing-plans
  • Batch execution with checkpoints for review

Task 1 complete. Stopping for review.

What changed:

  • cmd/entire/cli/checkpoint/committed_refs.go — added Push []plumbing.ReferenceName field; added PrimaryFetchableFromOrigin() method (using slices.Contains); resolver populates Push = [v1Branch] in both topologies; minor docstring update.
  • cmd/entire/cli/checkpoint/committed_refs_test.go — extended both resolver test tables with Push; new TestCommittedRefs_PrimaryFetchableFromOrigin with three cases (in-push, not-in-push, empty-push).

Verification:

  • go test -count=1 ./cmd/entire/cli/checkpoint/... — PASS (3 packages).
  • New tests run; existing tests run.
  • gofmt -s -w . clean.

Behavior change today: None. The new field is populated identically in both topologies; nothing reads it yet.

Commit and continue

3mo ago·5m

Task 2 done. Stopping per "continue means the next step, not all remaining steps."

What changed:

  • committed_refs.go — added DefaultV1Refs() constructor returning the v1-only topology; committedRefsFor now calls it as the base, then layers the v1.1 mirror on top when opted in.
  • committed_refs_test.go — added TestDefaultV1Refs asserting the v1-only shape.

Verification:

  • go test -count=1 ./cmd/entire/cli/checkpoint/... — PASS.

Ready to commit Task 2 and proceed to Task 3 (the wide GitStore constructor collapse)?

Commit and continue

3mo ago·22m

Task 3 complete. Stopping for review.

What changed:

  • checkpoint/store.go — rewritten. Single constructor NewGitStore(repo, refs CommittedRefs). New Refs() accessor. Removed defaultCommittedReadRef, NewGitStoreWithRef, the committedReadRef-only field.
  • checkpoint/committed_read_store.go — deleted.
  • checkpoint/committed.go — in-package NewGitStore(repo) call updated; getSessionsBranchTree fallback gated on Read == Primary && PrimaryFetchableFromOrigin(); getCheckpointAuthorFromRef call uses s.refs.Read; remote-tracking fallback uses refs.Primary.Short().
  • strategy/manual_commit.gogetCheckpointStore(repo) becomes getCheckpointStore(ctx, repo), resolves via ResolveCommittedRefs. getCommittedReadStore delegates.
  • strategy/{cleanup,common,manual_commit_*}.go — call-site updates to new constructor / ctx-aware getter.
  • resume.gopromoteRemoteTrackingMetadataBranch renamed to promoteRemoteTrackingPrimary(ctx, repo, refs); the committedReadRef == v1Branch bootstrap gate replaced with Read == Primary && PrimaryFetchableFromOrigin(); getMetadataTree resolves refs once and uses refs.Primary at all four tree-read sites; readCheckpointInfoFromRef and checkRemoteMetadata take CommittedRefs instead of a bare ref.
  • attach.goensureCheckpointAvailable and checkpointPresentLocally take CommittedRefs; store constructed from opts.committedRefs(ctx). Removed two now-unused imports.
  • Remaining production callers (benchutil, dispatch, explain, head_checkpoint_flags, review_context, rewind) updated to the new signature.
  • All test callers (~27 files) updated mechanically; the two TestNewCommittedReadStore_* tests renamed to TestNewGitStore_* and rewired through ResolveCommittedRefs.

Verification:

  • go build ./... clean.
  • go vet ./... clean.
  • go test -count=1 ./cmd/entire/cli/checkpoint/... ./cmd/entire/cli/strategy/... ./cmd/entire/cli/ — PASS.
  • mise run lint — 0 issues.

Behavior change today: None. Every site that previously resolved through old constructors now resolves through NewGitStore(repo, ResolveCommittedRefs(ctx)) (production) or DefaultV1Refs() (tests). Both produce the same topology as before.

Ready to commit Task 3 and start Task 4 (route committed writes through refs.Primary)?

Commit and continue

3mo ago·35m

Task 4 complete. Stopping for review.

What changed:

  • cmd/entire/cli/checkpoint/committed.go — replaced five plumbing.NewBranchReferenceName(paths.MetadataBranchName) write-site literals with s.refs.Primary.
  • cmd/entire/cli/checkpoint/parse_tree.gogetSessionsBranchRef (a write-path helper that resolves the parent commit/tree) now reads from s.refs.Primary; error message names the ref. Removed unused paths import.
  • cmd/entire/cli/checkpoint/committed_read_store_test.go — added TestGitStore_WriteCommittedTargetsPrimary proving the property: synthetic Primary advances, v1 branch is untouched.

Verification:

  • New test passes; full checkpoint/strategy/CLI test suites green.
  • mise run lint — 0 issues.

Behavior change today: None. refs.Primary resolves to the v1 branch in both v1-only and v1.1-canary modes.

Ready to commit Task 4 and start Task 5 (AdvanceCommittedPrimary helper + collapse the ~12 scattered SetReference + MirrorBestEffort pairs)?

commit and continue

3mo ago·9m

Task 5 complete. Stopping for review.

What changed:

  • cmd/entire/cli/strategy/v1_custom_ref_mirror.go — added AdvanceCommittedPrimary(ctx, repo, refs, hash); renamed exported MirrorCommittedMetadataRefBestEffort to unexported mirrorCommittedMetadataRefBestEffort(ctx, repo, refs) that takes refs explicitly. MirrorCommittedMetadataRef (strict) stays exported for attach/explain summary writes.
  • Strategy package collapse sites:
    • common.go EnsureMetadataBranch — 3 SetReference+MirrorBestEffort pairs collapsed into AdvanceCommittedPrimary calls; resolves refs once at function top.
    • metadata_reconcile.go ReconcileDisconnectedMetadataBranch — 2 pairs collapsed.
    • cleanup.go DeleteOrphanedCheckpoints — pair collapsed.
    • manual_commit_condensation.go, manual_commit_hooks.go (×2), checkpoint_remote.go, push_common.go mirrorSyncedMetadataBranch — mirror-only sites switched to the unexported best-effort helper.
  • cmd/entire/cli/git_operations.goMirrorCommittedMetadataRefBestEffort removed; since the helper is now unexported, this site calls the strict strategy.MirrorCommittedMetadataRef and logs failures.
  • Tests: extended v1_custom_ref_mirror_test.go with three AdvanceCommittedPrimary cases (no mirror, both refs advance, mirror failure best-effort via a selective storer).

Verification: full test suite green; mise run lint 0 issues.

Note: the four mirrorSyncedMetadataBranch call sites in push_common.go still go through the helper (which now uses the unexported best-effort under the hood). Folding them fully into AdvanceCommittedPrimary is bundled into Task 6's push/fetch generalization since that pass restructures the same call sites.

Ready to commit Task 5 and start Task 6 (push/fetch generalization)?

commit and continue

3mo ago·7m

Task 6 complete. Stopping for review.

What changed:

  • cmd/entire/cli/strategy/push_common.go:
    • pushBranchIfNeeded(target, branchName string)pushRefIfNeeded(target string, ref plumbing.ReferenceName). Branch refs keep the hasUnpushedSessionsCommon optimization; non-branch refs skip it and let git handle no-op pushes.
    • doPushBranchdoPushRef. Display strings use refDisplayName(ref) (short name for branches, full ref otherwise).
    • tryPushSessionsCommon builds a refspec — bare branch name for branches; +<ref>:<ref> force refspec for non-branch refs.
    • fetchAndRebaseSessionsCommon(target string, ref plumbing.ReferenceName) — refspecs generalized to use ref.String(). Non-branch refs always use a temp fetch ref since there's no remote-tracking shadow.
    • mirrorSyncedMetadataBranch deleted; the inner loop's 4 SetReference+mirror sites collapse into one advance(hash) closure → setLocalAfterSync, which routes through AdvanceCommittedPrimary when ref == refs.Primary and falls back to a plain SetReference (no mirror) otherwise.
  • cmd/entire/cli/strategy/manual_commit_push.go:
    • PrePush resolves CommittedRefs and iterates refs.Push, calling pushRefIfNeeded per ref. Today's one-element loop pushes the v1 branch unchanged.
  • Test files: pushBranchIfNeeded/doPushBranch call sites mechanically renamed; fetchAndRebaseSessionsCommon callers wrap branchName in plumbing.NewBranchReferenceName. New test TestPushRefIfNeeded_NonBranchRef proves the non-branch wiring against a local bare repo.

Verification:

  • New non-branch smoke test passes.
  • Full test suite green: ./cmd/entire/cli/checkpoint/..., ./cmd/entire/cli/strategy/..., ./cmd/entire/cli/.
  • mise run lint — 0 issues.

Behavior change today: None. refs.Push = [v1Branch] in both topologies, so PrePush pushes exactly the v1 branch as before.

3mo ago·2m

Task 7 complete. Stopping for review.

What changed:

  • cmd/entire/cli/explain.go:
    • loadV1MetadataRootTree(repo) renamed to loadPrimaryMetadataRootTree(repo, refs) — reads from refs.Primary, falls back to origin's remote-tracking ref only when reads are bootstrappable from origin (Read == Primary && PrimaryFetchableFromOrigin()). Error messages name the primary ref.
    • prefetchCheckpointBlobs resolves refs once and wraps the loader in a closure that captures them; label changed from "v1" to "primary".

Verification: full test suite green; lint clean.

Behavior change today: None. refs.Primary is the v1 branch in both topologies.

Note: most of plan Task 7 (the four resume.go migrations + bootstrap gate + promoteRemoteTrackingPrimary rename + attach.go checkpointPresentLocally) was already absorbed by Task 3, so this commit is a small follow-up just for the explain.go blob-prefetch path.

Task 8 complete. Stopping for review.

What changed:

  • cmd/entire/cli/strategy/common.go:
    • EnsureMetadataBranch(ctx, repo) renamed to EnsurePrimaryRef(ctx, repo).
    • Function now operates on refs.Primary instead of the v1 branch literal. Local ref lookup, remote-tracking ref name, and user-facing output strings all use refs.Primary / refs.Primary.Short().
    • The origin remote-tracking lookup is gated on refs.PrimaryFetchableFromOrigin() — when Primary isn't in Push, skip the bootstrap and go straight to "create empty orphan."
    • Orphan commit message generalized: "Initialize metadata ref" / "This ref stores session metadata."
  • Test files (common_test.go, metadata_reconcile_test.go, resume_test.go):
    • Callers renamed to EnsurePrimaryRef.
    • Test functions renamed (TestEnsureMetadataBranch_*TestEnsurePrimaryRef_*).
    • Descriptive strings/comments updated.

Verification: full test suite green; lint clean.

Behavior change today: None. refs.Primary == v1Branch and refs.PrimaryFetchableFromOrigin() is true in v1-only mode, so the function takes exactly the same paths as before.

Ready to commit and start Task 9 (final audit + manual_commit_logs.go trailer formatters)?

commit and continue

3mo ago·7m

Task 9 complete. The refactor is done.

What changed in this final pass:

  • strategy/common.go:
    • GetRemoteMetadataBranchTree(repo)GetRemotePrimaryTree(ctx, repo). Reads origin/<refs.Primary.Short()>, errors when Primary isn't in Push.
    • PromoteTmpRefSafely docstring example uses refs.Primary instead of the v1 literal.
  • strategy/manual_commit_logs.go:
    • GetMetadataRef / GetSessionMetadataRef commit-trailer formatters now use refs.Primary.Short(). Caller-visible trailer strings follow Primary.
  • strategy/cleanup.go: DeleteOrphanedCheckpoints reads from refs.Primary instead of the v1 literal.
  • strategy/metadata_reconcile.go:
    • IsMetadataDisconnected reads refs.Primary for the local-side check.
    • WarnIfMetadataDisconnected resolves refs once and skips entirely when Primary isn't in Push (origin doesn't track it).
    • ReconcileDisconnectedMetadataBranch operates on refs.Primary.
    • Removed unused paths import.
  • checkpoint/temporary.go: ListTemporary filters out the primary metadata branch via s.refs.Primary.IsBranch() && branchName == s.refs.Primary.Short() instead of the v1 literal.
  • doctor.go: checkDisconnectedMetadata resolves refs and gates on PrimaryFetchableFromOrigin; user-facing branch name uses refs.Primary.Short().
  • explain.go: loadPrimaryMetadataRootTree takes ctx (needed by the renamed remote-tree helper).
  • resume.go: caller of the renamed remote-tree helper updated.

Final audit of production references to paths.MetadataBranchName:

  • committed_refs.go:29 — the resolver itself (the chokepoint; required).
  • cleanup.go:68IsShadowBranch's structural v1 filter (legitimate v1 identifier check per spec).

Everything else now flows through CommittedRefs.

Verification: mise run check passed (fmt + lint + full unit + integration + E2E canary).

All 9 plan tasks complete. Branch is ready.

Summary of the work

9 commits on feat/checkpoints-v1.1-streamline-mirroring:

  1. checkpoint: add Push and PrimaryFetchableFromOrigin
  2. checkpoint: add DefaultV1Refs constructor
  3. checkpoint: collapse GitStore constructors into NewGitStore(repo, refs) — 38 files
  4. checkpoint: route committed writes through refs.Primary
  5. strategy: extract AdvanceCommittedPrimary helper
  6. strategy: generalize push and fetch to any ref
  7. explain: route metadata-blob prefetch through refs.Primary
  8. strategy: rename EnsureMetadataBranch to EnsurePrimaryRef
  9. strategy: finish refs.Primary migration

End state

  • CommittedRefs{Primary, Read, Mirror, Push} is the single source of truth. committed_refs.go is the only production code that names a specific version.
  • GitStore constructor takes CommittedRefs; writes target refs.Primary, reads target refs.Read.
  • AdvanceCommittedPrimary subsumes all SetReference + best-effort-mirror pairs.
  • Push and fetch helpers accept any plumbing.ReferenceName; PrePush iterates refs.Push.
  • A non-branch smoke test (TestPushRefIfNeeded_NonBranchRef) gates future v1.1-push work.
  • Every fallback-to-origin path is gated on Read == Primary && PrimaryFetchableFromOrigin(), so the local-only mirror keeps skipping origin correctly.

Behavior change today: None. All resolver outputs preserved.

Final verification: mise run check passed (fmt, lint, unit, integration, E2E canary).

The branch is ready to push and open as a PR whenever you'd like.

Code Review

1. Determine Diff Against origin/main

Always review changes against origin/main directly. Do not use local main, git merge-base, a PR base branch, or a user-specified alternate base.

Get the CURRENT diff — never use cached results from earlier in the conversation. Include both committed and uncommitted changes (staged + unstaged):

Note: git diff origin/main (not origin/main...HEAD) diffs origin/main against the working tree, capturing committed changes, staged changes, and unstaged changes in one pass.

Show the user the file list and total count. If there are 0 changed files, report that to the user and stop — there is nothing to review. Otherwise, immediately proceed to the review agents. Do NOT wait for confirmation.

Before launching agents, build a concise review context and pass it to every agent. Show the context as a table before launching agents so assumptions are visible:

ContextSourceValue
User goalConversationOne-line summary, or not provided
Implementation planConversation / docsOne-line summary, or not provided
PR contextPR title/bodyOne-line summary, or no PR found
Commitsgit log --oneline origin/main..HEADOne-line summary of commit intent
Changed surfacediff file listMain packages/files touched
Inferred behaviorcommits/tests/docs/user textIntended behavior change, or diff-only inference
  • The user's request and any implementation plan, design notes, or acceptance criteria provided in the conversation.
  • Branch commit messages from git log --oneline origin/main..HEAD.
  • PR title/body when a PR exists for the branch.
  • The changed-file list and any obvious intended behavior changes inferred from commits, tests, docs, or user-facing text.

Treat this context as the statement of intent. If no implementation plan or PR context exists, say that intent is inferred from the diff and commits only.

2. Spawn Parallel Review Agents

Review Philosophy

Pass these rules to every agent:

  • It is OK to find nothing. A clean review is a valid outcome. Do NOT manufacture findings to justify the review. Only flag issues you are confident are real problems.
  • Be opinionated and consistent. If a pattern is acceptable, don't flag it. If you flag something, commit to that position — don't suggest the opposite approach on a re-review.
  • Don't flag trade-offs with no clear winner. If there are two reasonable approaches and neither is clearly better, don't flag it. The author already made a choice.
  • High confidence only. Every finding must pass the bar: "I am confident this is a problem, and I can explain specifically what goes wrong if it's not fixed." Vague unease is not a finding.
  • Permission-friendly reads. Avoid shell pipelines, command separators, subshells, and output filters for read-only investigation because they create extra permission prompts and block background review agents. Do not run commands like git show HEAD:path | sed -n '10,40p'. Use workspace file range reads, rg with path limits, path-scoped git diff $BASE -- <path>, or one standalone git show <rev>:<path> only when the output is acceptably small.
  • Intent-aware review. Review changed code against the review context, not against the old behavior alone. Do not classify an intentional behavior change as Required merely because it differs from origin/main. A Required finding must either contradict stated intent, break an existing contract that the intent did not change, introduce a concrete bug/security issue, or leave the intended behavior unverified in a way that would likely fail.

Launch four baseline sub-agents in parallel using the Agent tool. Pass each agent origin/main as the base ref, the full list of changed files, the review context, and the review philosophy above.

When the repository is a Go project and the diff includes Go-related files (*.go, go.mod, or go.sum), also launch Agent 5 in the same batch. Do not run the Go-specific agent for non-Go diffs.

Agent 1: Security & Adversarial

Review git diff $BASE for:

  • Injection — command injection, SQL injection, path traversal
  • TOCTOU and race conditions — check-then-act patterns, concurrent access without synchronization
  • Unvalidated input at system boundaries — user input, API parameters, external data
  • Auth/authz gaps — missing permission checks, privilege escalation paths
  • Secrets or credentials — hardcoded tokens, leaked keys, credentials in code or config

For EACH finding: read the actual source file and trace whether the code path is reachable in production. Discard any finding you cannot confirm with a concrete code reference.

Agent 2: Correctness & Quality

Review git diff $BASE for:

  • Logic errors — off-by-one, wrong comparison, inverted conditions
  • Nil/null handling — unchecked nil dereferences, missing error checks (especially unchecked errors in Go)
  • Edge cases in concurrency — goroutine leaks, missing locks, channel misuse, deferred unlock ordering
  • Redundant state — state that duplicates existing state, cached values that could be derived
  • Production test seams — mutable function variables, package-wide settings, reset hooks, or exported knobs added only so tests can swap behavior instead of using dependency injection or a higher-scope test
  • Parameter sprawl — adding new parameters instead of restructuring
  • Leaky abstractions — exposing internal details, breaking existing abstraction boundaries
  • Stringly-typed code — using raw strings where constants or typed values already exist in the codebase
  • Test coverage and scope gaps — changed behavior, edge cases, or error paths not exercised by meaningful tests; tests that prove implementation details instead of behavior; or unit tests used where integration/e2e coverage is the right confidence boundary
  • Test helper over-abstraction — helpers that hide the behavior, expected values, or assertions and make the test harder to understand than a small amount of duplication

For EACH finding: verify the claim by reading the source. Check call sites to confirm the issue is real, not hypothetical.

Agent 3: Simplification & Efficiency

Review git diff $BASE for:

  • Dead code — unreachable branches, unused functions, struct fields that are never read
  • Code reuse — search for existing utilities and helpers that could replace newly written code; flag duplicated functionality
  • Copy-paste with variation — near-duplicate blocks that should be unified
  • Unnecessary abstractions — wrapper types, indirection, or overly defensive fallbacks that mask errors
  • Unnecessary work — redundant computations, repeated file reads, duplicate API calls, N+1 patterns
  • Missed concurrency — independent operations run sequentially when they could be parallel
  • Hot-path bloat — blocking work added to startup or per-request paths
  • Unnecessary existence checks — pre-checking file/resource existence before operating (TOCTOU anti-pattern); operate directly and handle the error
  • Unnecessary comments — comments explaining WHAT the code does (well-named identifiers already do that); keep only non-obvious WHY

For EACH suggestion: verify it does not break existing behavior by checking call sites and usages. Discard cosmetic-only suggestions (renames, formatting).

Agent 4: Readability & Go Idioms

Review git diff $BASE for code that is hard to read, maintain, or reason about:

  • Poor factoring — functions doing multiple jobs, tangled control flow, or missing helper extraction where a small local helper would clarify behavior
  • Mixed abstraction levels — high-level orchestration mixed with low-level IO, parsing, protocol, or data-structure details; low-level helpers that also make workflow or policy decisions
  • Generated-code smell — repetitive pasted logic, shallow wrappers, generic names, or code that reads like it was assembled without domain intent
  • Data-flow opacity — values transformed across too many steps, unclear ownership, hidden mutation, pass-through helper chains, or state threaded through unrelated code
  • Control-flow complexity — deeply nested conditionals, boolean flag plumbing, early returns used inconsistently, or error paths that obscure the main path
  • Naming clarity — names that hide domain meaning or force callers to inspect implementation to understand usage
  • Go API readability — ambiguous (result, bool) returns outside clear comma-ok/presence checks, oversized interfaces, unnecessary pointer indirection, or cleverness where explicit Go would be clearer
  • Error readability — errors that lose operation/context, wrap inconsistently, or make call sites branch on strings/booleans instead of clear errors or typed status

For EACH finding: explain the readability cost in concrete maintenance terms. Prefer small, local refactor suggestions. Discard formatting-only, gofmt-only, or personal taste comments.

Agent 5: Clean Go & Modern Go (Go diffs only)

Use the local pfleidi:clean-go skill as the source of truth: skills/pfleidi/clean-go/SKILL.md.

Review only changed Go code plus surrounding source, tests, interfaces, and call sites needed to verify findings. Apply the skill's Clean Go checks and version-gated Modern Go checks. This includes the modern-go guidance incorporated from JetBrains' use-modern-go skill: detect the relevant go.mod target version, only suggest features available for that version, and do not perform blanket modernization.

Focus on concrete changed-code findings around composable functions, abstraction level, function size/signatures, errors, pointers, small interfaces, any/interface{}, testing guidance from skills/pfleidi/testing/SKILL.md, and modern standard-library helpers. Discard findings that would merely restyle existing code or require a broad rewrite unrelated to the current diff.

Second-Pass Coverage Sweep

After the first-pass agents complete, run a second independent review pass before synthesis. The goal is recall: catch high-confidence findings that the lens-specific agents may have missed.

Launch one fresh coverage agent with origin/main as the base ref, the full list of changed files, the review context, and the review philosophy above. Do not pass the first-pass findings to this agent.

Ask the coverage agent to:

  • Re-read the changed files and the surrounding code needed to understand each changed path.
  • Trace changed behavior through callers, callees, tests, configuration, migrations, generated interfaces, and user/API entry points where relevant.
  • Search the repository for related patterns, duplicated logic, and existing helpers that affect the changed code.
  • Look across all lenses together: security, correctness, tests, simplification, readability, performance, and Go cleanliness when applicable.
  • Prioritize missed Required findings over optional improvements.
  • Return only high-confidence findings with concrete file:line evidence and a short explanation of the traced path.

Then compare the second-pass findings with the first-pass findings. Deduplicate overlaps, verify any new claim by reading source yourself, and discard anything that cannot be confirmed.

3. Synthesize Report

After all launched agents complete:

  1. Collect findings from both the first-pass agents and the second-pass coverage sweep
  2. Deduplicate — merge findings from different agents that point to the same underlying issue
  3. Verify — for any finding where the agent did not cite a specific file:line with evidence, read the source and confirm or discard it
  4. Group by file
  5. Sort by severity within each file: Critical > High > Medium > Low

Severity Definitions

  • Critical — Must fix before merge. Bugs, security vulnerabilities, data loss risk, race conditions with observable impact.
  • High — Should fix before merge. Missing error handling, meaningful test gaps, performance issues on hot paths.
  • Medium — Worth fixing. Code reuse opportunities, unnecessary complexity, readability problems that make future changes error-prone, minor efficiency improvements.
  • Low — Optional. Minor readability improvements or cosmetic suggestions.

Relevance Classification

For each finding, classify as:

  • Required — The change does not work correctly without this fix in light of the review context. Bugs, missing error handling that causes failures, security vulnerabilities, race conditions, contradictions of stated intent, or missing tests for intended behavior that would likely fail. The branch should not merge without addressing these.
  • Improvement — Valid finding, but the change works correctly without it. Better factoring, clearer Go APIs, using existing helpers, code reuse, unnecessary complexity, style. Worth addressing in a follow-up, not in this branch.

Autofix Eligibility

Mark each Required finding as Autofix eligible or Needs decision:

  • Autofix eligible — source-backed, high confidence, minimal fix is clear, no new dependencies, no shared/public interface change, no product/design choice, no broad refactor, and the directly related verification path is clear.
  • Needs decision — any Required finding that fails one of the autofix checks, including intentional behavior questions, API shape changes, cross-cutting refactors, or fixes where multiple reasonable approaches exist.

Present findings as compact tables, not prose blocks. Use one summary table for scanning and one details table for evidence and fixes.

Summary table format:

#SeveritySourcesLocationClassificationAutofixIssueImpact
1Mediumcorrectness + coveragecmd/entire/cli/checkpoint/v2_committed.go:234RequiredEligibleOne-sentence problem.Concrete consequence if not fixed.

Details table format:

#EvidenceSuggested fixTrade-offs
1Source-backed confirmation from code path, call site, or test gap.Concrete code change, not vague advice.One sentence, or None if strictly better.

Keep table cells short and scannable. Put the smallest useful quote or evidence in the table rather than full paragraphs. Escape | characters inside code or text so the table remains valid Markdown. Use n/a for Autofix on Improvements. The Sources column lists the agents that independently found or confirmed the issue, such as security, correctness, readability, clean-go, or coverage.

If no findings exist at a severity level, omit that section.

If there are 0 findings across all agents, report that the review is clean and stop.

4. Present Report and Proceed With Default Fixes

Present findings in two sections:

Required

Table of findings classified as Required, sorted by severity. Include the Autofix value for each finding. Follow it with the details table for those same Required findings.

Improvements (follow-up)

Table of findings classified as Improvement, continuing the numbering. These are presented for awareness but are NOT included in the fix cycle by default. Follow it with the details table for those same Improvement findings.

End with a one-paragraph summary: total required vs improvement findings, overall merge-readiness assessment, and any patterns across files.

Before editing, present a planned-autofix table for Autofix eligible Required findings:

#LocationPlanned changeRelated test/verificationFiles expected
1path/file.go:42Minimal code change to address the finding.Focused test or lint/build command.path/file.go, path/file_test.go

Do not ask the user to choose a mode. Immediately proceed to Step 5 for Autofix eligible Required findings after showing the planned-autofix table. Do not fix Improvements by default.

If there are Required findings but none are Autofix eligible, stop after the report and list the exact decisions needed.

5. Fix Cycle

Scope Rules

  • Make the MINIMAL change that addresses the finding
  • Keep the diff limited to files and lines directly required by the finding
  • First decide whether the finding is local or systemic. Fix at the narrowest correct level; do not add a local workaround that hides a shared/root-cause bug.
  • If the finding requires a behavior-changing code fix, add or update the directly related test in the same fix step. Prefer TDD, but complete the focused red-to-green cycle before stopping: write/update the failing test, confirm it fails, implement the fix, confirm the focused test passes. Do not stop after only adding the failing test unless the user explicitly asks.
  • Do NOT rename variables, reformat code, or touch lines outside the finding scope
  • Do NOT refactor adjacent code, even if it looks related
  • Do NOT create any git commits — code changes only

Default Batched Fixes

Fix all Autofix eligible Required findings in report order by default. Do not ask which findings to fix.

Choose an artifact directory using the AGENTS.md temporary artifact rule with agent name pfleidi-review:

  • Use ./tmp/pfleidi-review/ only when ./tmp/ already exists and is already ignored.
  • If no project-local artifact directory is available, do not create file artifacts by default; keep ledger/log/cache information in the response and mark file paths n/a. Ask before using /tmp/pfleidi-review/ or modifying ignore files.

When an artifact directory is available, create a temporary fix ledger at <artifact-dir>/review-<repo-name>-<timestamp>.md before editing. If no artifact directory is available, keep the same ledger fields in the final summary table instead. Update the ledger after each finding with:

  • Finding number, status, and source location.
  • Files touched.
  • What changed and why.
  • Related tests or verification commands.
  • Rollback notes sufficient for the user to understand how to revert the finding-specific change manually.

For each Autofix eligible finding:

  • Read the relevant code to confirm the fix approach
  • Re-check eligibility before editing; if the fix is no longer clearly eligible, mark it Needs decision and continue to the next finding
  • Implement the fix — ONLY the code changes for that single finding
  • Add or update the directly related test in the same diff when the fix changes behavior; if using TDD, complete red-to-green before moving on; if no test is added, state why
  • Keep the diff limited to files and lines directly required by that finding
  • If a fix would require changing a function signature in a shared interface, adding a dependency, expanding scope outside the finding, or making an ambiguous product/design choice, skip that finding as Needs decision and continue
  • Track the exact files changed, what changed, and why the change addresses the finding

If a skipped finding has partial edits, remove only your own partial edits for that finding before continuing. If you cannot safely isolate those partial edits, stop and explain the conflict.

After all eligible fixes are applied, proceed directly to Step 6 (Verify Fixes). Do NOT show a diff yet.

6. Verify Fixes

Run the project's lint and test commands scoped to only the changed files and their directly related tests. Use safe background batches for independent validators instead of running every command sequentially.

When selecting verification commands, reuse <artifact-dir>/verification-<repo-name>.md if an artifact directory is available and the cache is fresh under the cache rules from pfleidi:pr; otherwise discover the smallest relevant lint/test/build commands. Update the cache only when an artifact directory is available.

  • Lint / static analysis — run the project's documented lint task, scoped to the files that were modified by the fixes when the task supports scoping. Prefer lint-specific task wrappers such as make lint or mise run lint over invoking linter binaries directly. Do not use aggregate check, ci, or verify tasks unless you have confirmed they only run lint/static analysis. If the documented lint task cannot be scoped, run the smallest relevant project lint task.
  • Tests — run only the test files that cover the modified code (same package, same module, co-located test files). Do NOT run the full test suite.

If no project lint task exists, state that explicitly instead of assuming an unavailable linter binary.

Run formatters, generators, snapshot updates, or other mutating commands alone before validators that depend on their output. Run independent read-only validators concurrently when they do not require the same exclusive service, port, database, fixture directory, or generated output. Keep integration/e2e/service-backed commands separate unless the project documents that they are parallel-safe.

For each background batch, start every command from the same working-tree state, capture stdout/stderr/exit status from the tool, do not edit files while the batch is running, and wait for every command to finish. Run each selected validator directly, for example mise run lint, go test ..., or npm test -- .... Do not wrap validators in sh -c, shell redirection, tee, command separators, or pipelines solely to write logs; that defeats command-prefix approvals and causes extra permission prompts. If an artifact directory is available and file logs can be written after the command completes without rerunning through a shell wrapper, save them under <artifact-dir>/logs-<repo-name>-<timestamp>/; otherwise mark the full-log path as n/a. If files change after a failed batch, none of that batch's successful results count as current verification.

Show verification as a compact table:

CommandExitRelevant outputFull log
go test ./pkg/foo -run TestBar -count=10Short success excerpt.<artifact-dir>/logs-.../go-test-pkg-foo.log or n/a

For failures or short outputs, show complete output in the relevant-output column or immediately below the table. For long successful outputs, show the relevant excerpt and log path.

On Failure: Auto-Fix

If lint or tests fail due to issues introduced by the review fixes:

  1. Read the error output and identify every failure
  2. Fix all issues — apply the minimal changes needed
  3. Re-run the failing commands using the same safe batching rules
  4. Show the complete output again

Cap at 2 fix attempts. If still failing after 2 rounds, present the remaining failures to the user with full output.

7. Present Results

Once verification passes (or the user has seen the remaining failures), present a summary table. Do NOT show a diff — the Edit tool already showed each change inline.

#FindingFileStatusWhat changedWhy
1Descriptionpath:lineFixedAdded nil check in fooPrevents panic on missing config
3Descriptionpath:lineFixedAdded focused test for invalid inputVerifies intended error path
6Descriptionpath:lineNeeds decisionNoneAPI shape has two reasonable options

Also present a rollback/traceability table and the ledger path:

#Files touchedRollback notes
1path/file.go, path/file_test.goRevert the nil-check and focused test added for finding #1.

Ledger: <artifact-dir>/review-<repo-name>-<timestamp>.md, or n/a when no project-local artifact directory was available.

STOP and wait. The user decides what to commit.

8. Post-Fix

  • If the user asks for changes, apply them
  • If the user asks to revert specific fixes, revert ONLY those changes using surgical git checkout of the affected lines
  • Do NOT commit. The user handles commits on their own terms.

Commit: ab023acb5c address review feedback for streamline-mirroring refactor

Ledger: tmp/pfleidi-review/review-cli-2026-06-04.md

ab023acaddress review feedback for streamline-mirroring refactor Required: - explain.loadPrimaryMetadataRootTree: drop the Read != Primary clause from the origin-fallback gate. The function reads Primary's tree, so whether reads bootstrap from origin is irrelevant. - strategy: inline getCommittedReadStore (one-line wrapper) into its sole caller in manual_commit_condensation. Improvements: - CommittedRefs.PrimaryFetchableFromOrigin: require Primary.IsBranch(). Non-branch refs don't get refs/remotes/origin/<name> shadows. - CommittedRefs.ReadBootstrappableFromOrigin: extract the predicate used at three sites (resume bootstrap gate, resume remote-metadata check, GitStore fallback) so the gate has a name. - attach, explain: drop the redundant outer HasMirror() guard around MirrorCommittedMetadataRef; the function already short-circuits. - push_common: inline setLocalAfterSync into fetchAndRebaseSessionsCommon and resolve refs once at the top instead of per advance step. - cleanup: pass already-resolved refs into the final AdvanceCommittedPrimary call instead of re-resolving. - v1_custom_ref_mirror_test: populate Push in v1CustomRefsForTest so the helper matches what the resolver actually produces. - push_common_test: add TestFetchAndRebase_NonBranchRef. - attach.checkpointPresentLocally: route the read through a Primary-bound store so the result reflects the write target, not the configured read ref. - push_common.pushRefIfNeeded: log a Debug when OpenRepository fails instead of silently returning nil.

Create Pull Request

1. Understand the Branch

Use origin/main as the comparison base for understanding branch scope. Do not use local main, a local PR target branch, or direct tree diffs such as git diff main or git diff origin/main for scope checks; those can include upstream-only changes and make this branch look like it reverted unrelated work.

Read the commit history to understand the full scope of changes on this branch.

Review the changed file list from the merge base to the current working tree and confirm every changed file belongs to the PR's stated goal:

If unrelated files or commits are present, STOP and report them. Do not create a PR that bundles unrelated work.

2. Discover Project Verification Commands

Inspect the project to determine how to build, lint, and test. Collect candidate commands from these sources, then deduplicate them before running anything:

  1. Makefile — look for build, lint, check, test, ci, verify targets. Read the target recipes to understand what they run.
  2. mise — check for .mise.toml or .mise/*.toml. Look for [tasks] definitions covering build, lint, test. If found, use mise run <task>.
  3. CI workflows — read .github/workflows/*.yml (or .gitlab-ci.yml, etc.) to understand required coverage. CI is the ground truth for what must pass, but CI matrix shards and CI-only wrappers are not automatically local verification commands.
  4. README.md — look for "Development", "Contributing", "Building", or "Testing" sections that document how to run checks.
  5. Package manager conventions — detect from project files:
    • go.modgo build ./..., go vet ./..., go test ./...; do NOT infer a lint command from Go alone
    • package.json → check scripts for build, lint, test
    • Cargo.tomlcargo build, cargo clippy, cargo test
    • pyproject.toml / setup.py → check for configured linters, pytest

If no lint command exists after checking all sources, state that explicitly instead of assuming an unavailable linter binary.

Reuse Cached Verification Discovery

Before rediscovering commands from scratch, choose an artifact directory using the AGENTS.md temporary artifact rule with agent name pfleidi-pr:

  • Use ./tmp/pfleidi-pr/ only when ./tmp/ already exists and is already ignored.
  • If no project-local artifact directory is available, do not use a verification cache by default. Ask before using /tmp/pfleidi-pr/ or modifying ignore files.

When an artifact directory is available, check for a verification cache at <artifact-dir>/verification-<repo-name>.md. The cache is only an input-token optimization; never commit it and never trust it blindly. If no artifact directory is available, perform normal discovery and skip writing the cache.

Reuse the cache only when all of these are true:

  • It names the same worktree root and remote.
  • It lists the verification source files it was based on, such as Makefile, .mise.toml, .mise/*.toml, CI workflow files, README files, and package manifests.
  • Those source files still exist or are still intentionally absent.
  • git diff --name-only origin/main -- <source files> shows no branch changes to those source files.

If the cache is missing, stale, or incomplete, perform normal discovery. After discovery, update the cache with:

  • Repository root and remote.
  • Verification source files inspected.
  • Selected command plan grouped by coverage area.
  • Commands intentionally skipped as duplicates, aggregate/subtask overlaps, CI-only jobs, or too-slow shard matrices.
  • Any assumptions, such as "no documented lint task found."

Deduplicate Verification Commands

Build a command plan by coverage area, not by source. Do not run every command discovered.

  • Run at most one command for each coverage area: build/compile, lint/static analysis, unit/core tests, integration tests, e2e/smoke tests.
  • Prefer documented local developer tasks over CI-specific commands when they cover the same area.
  • Do not run both an aggregate task and its constituent tasks. For example, if mise run check runs lint and tests, either run mise run check alone or run the narrower lint/test tasks, not both.
  • Treat CI matrix shards as duplicated slices of one suite. Do not run every *:shard:* command locally when an unsharded local task covers the suite.
  • If CI has only sharded commands and no local equivalent, ask before running all shards. Otherwise, run the smallest representative or changed-scope test command and note that the full shard matrix remains for CI.
  • Do not run CI-only canary/e2e jobs locally by default. Run them only when the PR changes that surface, when the user asks, or when the project documents them as required local PR verification.

Log which sources you used, which duplicate/CI-only commands you skipped, and what commands you will run. If the deduplication rules require asking before slow CI-only coverage, STOP for confirmation; otherwise immediately proceed to step 3.

3. Run Verification and Auto-Fix

Run the deduplicated command plan in the fewest safe batches. Prefer background processing for independent validation tasks instead of running everything sequentially.

The commands should cover, at minimum:

  • Build — the project compiles without errors
  • Lint / static analysis — no lint warnings or static analysis failures
  • Tests — the selected local test coverage passes without duplicating CI shards or aggregate/subtask combinations

Use the exact commands, flags, and build tags found in step 2 for the commands you selected. Do not invent your own flags.

Parallel Verification Rules

Partition the selected commands into dependency-safe batches before running them:

  • Run mutating commands alone and before validators that depend on their output. This includes formatters, generators, codegen, migrations, package installation, or commands known to update snapshots, lockfiles, generated files, caches in the repo, or test fixtures.
  • Run dependent commands after their prerequisite batch passes. For example, do not start tests that require generated code until generation succeeds.
  • Run independent read-only validation commands concurrently in the same background batch. Build, lint/static analysis, typecheck/vet, and unit tests can usually share a batch when they do not mutate the working tree and do not require the same exclusive service, port, database, or fixture directory.
  • Keep integration, e2e, or service-backed commands separate unless the project documents that they are parallel-safe.
  • If unsure whether two commands are independent, run them sequentially. Correctness of validation beats speed.

For each background batch:

  1. Start every command from the same working-tree state.

  2. Run each selected validator directly, for example mise run lint, go test ..., or npm test -- .... Do not wrap validators in sh -c, shell redirection, tee, command separators, or pipelines solely to capture logs; that defeats command-prefix approvals and causes extra permission prompts.

  3. Capture each command's stdout, stderr, exit status, and command line from the tool output separately.

  4. While the batch is running, do not edit files, start auto-fixes, or treat partial output as a result.

  5. Wait for every command in the batch to finish, then show verification as a compact table:

    CommandExitRelevant output
    go test ./pkg/foo -run TestBar -count=10Short success excerpt.
  6. For failures or short outputs, show complete output in the relevant-output column or immediately below the table. For long successful outputs, show the relevant excerpt and state that the rest was truncated.

  7. If any command in the batch fails, treat the whole batch as failed for the fix loop. Results from other commands in that stale batch may help diagnose, but they do not count as passing verification after files change.

On Failure: Fix and Re-verify

If any command fails, do NOT stop. Instead:

  1. Read the error output and identify every failure
  2. Fix all issues — apply the minimal changes needed to make the failing command pass
  3. Re-run the deduplicated verification plan from the top, using the same safe batching rules (not just the previously failing command — fixes can introduce new issues)
  4. Show the updated verification table again, including complete failure output for any command that still fails

Repeat this cycle until all commands pass. Cap at 3 fix attempts. If verification still fails after 3 rounds, STOP and present the remaining failures to the user with full failure output — do not keep looping.

4. Prompt for Commit

After all verification passes, check for uncommitted changes:

If there are uncommitted changes (from auto-fixes in step 3):

  1. Show the diff of all uncommitted changes
  2. Propose a semantically correct commit message using the subject-plus-context style from AGENTS.md. The message must describe the net fix (e.g., "fix lint warnings in config parser" not "fix issues found during PR prep").
  3. STOP and wait for user approval. The user may edit the message, split the changes, or commit themselves.

If the user approves the commit, do not rerun the full verification suite before committing unless files changed after step 3. If another sanity check is needed, use the commit-time verification scope from AGENTS.md: lint tasks, a fast compile/build check, and tests directly related to the changed code only.

If there are no uncommitted changes, proceed directly to step 5.

5. Push the Branch

If the branch has no upstream yet, use git push -u origin HEAD.

6. Create the PR

Determine a concise PR title (under 70 characters) from the commit history and diff.

Use the same branch-only comparison from step 1 ($MERGE_BASE to the current working tree) when deriving the title, PR body, changed-file list, and mostly-Markdown detection. Do not use local main or direct git diff origin/main output for PR description decisions.

Write the PR body with:

  • What this PR does and why
  • How it was implemented (brief, not exhaustive)
  • Any migration, deployment, or reviewer notes if applicable
  • For mostly Markdown PRs, a Rendered Markdown section linking to the changed Markdown files rendered on GitHub

Create the PR:

Create a ready-for-review PR only when the user explicitly asks for it with wording such as "non-draft", "ready for review", or "publish it as ready". In that case, omit --draft.

Show the PR URL and STOP.

Rules

  • Do NOT add "Generated with Claude Code" or any AI attribution anywhere
  • Do NOT summarize what you just did after showing the URL
  • Treat a PR as "mostly Markdown" when more than half of changed files are Markdown (.md, .mdx, .markdown) or the main review target is Markdown documentation. In that case, include GitHub rendered links for the changed Markdown files using the pushed branch, e.g. https://github.com/<owner>/<repo>/blob/<branch>/<path>.md. Link all changed Markdown files when the list is short; for large docs PRs, link the main entry points or most important changed files.
  • If the user provides a title or description, use it verbatim instead of generating one, but append rendered Markdown links for mostly Markdown PRs unless the user explicitly says not to modify the description.
  • If the PR description contains checklist items (- [ ]), check them (- [x]) if and only if the corresponding step was actually verified during this workflow (e.g., build passed, tests passed, lint passed). Do NOT check items that were not verified. Do NOT leave items unchecked if they were verified.

There are uncommitted changes I didn't make — looks like in-progress user edits to attach.go (replacing the ReadSessionContentByID defense-in-depth guard with a new checkpointHasSessionMetadata helper) and a new test in attach_test.go. These are unrelated to my mirroring refactor.

The changes have just been comitted

Pushed. Step 6 — Create the PR.

Can you add a bit more details in regard to why this change was made and what problems it's trying to solve etc?

3mo ago·55.7s

Before creating the PR, two things to surface:

  1. Expanded PR body — I've drafted a version with more "why" context (see below). Confirm or edit before I run gh pr create.
  2. Uncommitted changes — 12 files are modified locally but not yet committed/pushed (metadata_reconcile.go, checkpoint_remote.go, doctor.go, explain.go, several tests, the design doc). The PR I'd open from the pushed tip won't include them. Do you want to commit and push those first, or open the PR as-is and roll those in as a follow-up commit?

Proposed PR body:

Let me know which option for the uncommitted changes and whether the body above is good (or what to tweak).

Can you improve the description a bit more given these parameters:

  • The reaoning behind a change and why it exists is often very sparse
  • Especially for bot reviews, some decisions being made during the implementation aren't clear so bots will often flag the same issues over and over again.
  • The description should create tradeoffs and considerations. If it applies, we should also list options we considered and decided against.
  • There's large sections with test plans that lists cli commands and newly added tests that's not helpful for a reviewer at all. We should skip that.
3mo ago·1m

Same two open questions:

  1. Approve / edit this body?
  2. The 12 uncommitted local edits (metadata_reconcile.go, checkpoint_remote.go, doctor.go, explain.go, tests, design doc) — commit and push first, or open the PR off the pushed tip and follow up?

The feat/checkpoints-v1.1-rewind-clean has been merged already so the note about the commits beloging to it don't apply anymore.

3mo ago·2m

Origin/main has been advanced — the merge-base is 0eb285c (the old prereq tip), my branch is 11 commits ahead, only my refactor changes show up in the proper merge-base diff. GitHub's PR view uses that scope, so the prereq references can come out of the body cleanly.

Revised PR body (removed prereq mentions):

Still pending: 12 files modified locally but not pushed (metadata_reconcile.go, checkpoint_remote.go, doctor.go, explain.go, several tests, the design doc). Commit and push before the PR, or PR off the current pushed tip and follow up?

Feel free to open the PR now. The other modified files will be committed in a different terminal soon

Can you pull in main and resolve the merge conflicts and then push again?

3mo ago·6m

Pushed. PR https://github.com/entireio/cli/pull/1376 now contains the merged tree.

Merge summary:

  • One content conflict in cmd/entire/cli/strategy/v1_custom_ref_mirror.go. Main added MirrorStatus/MirrorDiagnosis/DiagnoseCommittedMetadataMirror (used by doctor.go and doctor_bundle.go); my branch added AdvanceCommittedPrimary. Resolved by keeping both — additive merge.
  • One test from main needed a signature update (resume_test.go:982 used the old NewGitStore(repo) API). Fixed.
  • Pre-existing unrelated test failure on main: TestRunAuthStatus_RendersSessionsTable has hardcoded "2026-01-01" dates that aged out (today is 2026-06-04). Not in this PR's scope.

Lint clean. Refactor's packages (checkpoint/..., strategy/...) all green.

Base directory for this skill: /Users/pfleidi/.agents/skills/pfleidi/skills/pr-feedback

PR Feedback

1. Identify the PR

If the user provided a PR number or URL, use that. Otherwise, detect from the current branch:

If no PR exists for the current branch, stop and tell the user.

2. Fetch Review Comments

Fetch PR metadata first so comment decisions have intent context:

Also collect branch commits and changed files for context:

Show the PR context as a table before classifying comments:

ContextSourceValue
PRtitle/bodyOne-line PR intent
BranchcommitsOne-line commit summary
Changed surfacediff file listMain packages/files touched
Base/headPR metadatabase <- head

Fetch unresolved review threads with GraphQL as the primary source of truth. Group work by thread, not by individual REST comment:

Filter to unresolved threads only. If there are no unresolved threads, report that to the user and stop — there is nothing to fix.

If GraphQL pagination indicates more review threads or thread comments are available, paginate before classifying. Do not classify a partial thread set as complete.

Use REST pull-review comments only as a fallback when GraphQL data is incomplete or a thread cannot be mapped to a review comment ID:

When REST fallback is used, deduplicate by GraphQL thread ID first, then by file/line/body/author. Do not present or fix the same review request twice.

3. Parse, Classify, and Group

Use permission-friendly reads while investigating comments. Avoid shell pipelines, command separators, subshells, and output filters for read-only source inspection because they create extra permission prompts and can block background work. Do not run commands like git show HEAD:path | sed -n '10,40p'. Use workspace file range reads, rg with path limits, path-scoped diffs, or one standalone git show <rev>:<path> only when the output is acceptably small.

For each comment, extract:

  • Author — who left it
  • Author type — bot, automated reviewer, human reviewer, or maintainer
  • File and line — where it points
  • Body — the actual feedback (verbatim, not paraphrased)
  • Thread context — any replies in the same thread (to understand if it was already discussed or resolved conversationally)
  • Thread ID and comment ID — the GraphQL review thread ID and original comment ID needed to reply and resolve

Group each unresolved review thread into a single finding. If multiple comments in one thread refine or supersede each other, use the latest unresolved reviewer request as the finding and retain the earlier messages as context.

Classify each finding source:

  • Bot — GitHub bot, CI system, or linter/static-analysis account such as github-actions[bot] or codecov[bot]
  • Automated reviewer — review-assistant accounts that produce natural-language suggestions, such as Copilot or CodeRabbit
  • Human reviewer — non-bot reviewer
  • Maintainer — repository owner/member/maintainer when that can be inferred from GitHub metadata

4. Present Findings

Present two separate sections:

Human Comments

Table ordered by:

  1. Bugs / correctness issues — reviewer identified broken logic or missing error handling
  2. Design / architecture feedback — structural changes, API shape, naming of public interfaces
  3. Style / nits — formatting, naming of local variables, minor readability

Use this table format:

#PriorityLocationReviewerRequestKey quoteAutofix
1Bugfile.go:42reviewerOne-line summary of what the reviewer is asking for.Short verbatim excerpt.Eligible, or Needs decision with the exact decision needed.

For automated reviewers, use the same table and set Reviewer to the tool account, with Priority based on the substance of the request.

Bot Comments (batched)

Table continuing the numbering from above, grouped by tool/bot:

#BotLocationRequired fixAutofix
8linter-namefile.go:42One-line summary of the required fix.Eligible, or Needs decision with the exact decision needed.

Keep table cells short and scannable. Use the smallest useful verbatim quote, not the full comment body. Escape | characters inside code or text so the table remains valid Markdown.

End with a summary: total human comments, total bot comments, overall assessment of effort.

Do not stop for mode selection. Proceed by default with bot comments and human comments marked Autofix eligible. Mark a human comment Autofix eligible only when the requested change is source-backed, high confidence, minimal, unambiguous, does not require a product/design decision, does not add a dependency, does not change a shared/public interface, and has a clear verification path.

Leave all other human comments unresolved as Needs decision, with the exact decision needed. Do not reject a reviewer comment by default; rejection requires a user-provided public rationale.

Before applying any fixes, record the starting commit:

Choose an artifact directory using the AGENTS.md temporary artifact rule with agent name pfleidi-pr-feedback:

  • Use ./tmp/pfleidi-pr-feedback/ only when ./tmp/ already exists and is already ignored.
  • If no project-local artifact directory is available, do not create file artifacts by default; keep ledger/log/cache information in the response and mark file paths n/a. Ask before using /tmp/pfleidi-pr-feedback/ or modifying ignore files.

When an artifact directory is available, create a temporary thread ledger at <artifact-dir>/pr-feedback-<pr-number>.md. If no artifact directory is available, keep the same ledger fields in the final summary table instead. Update the ledger after each thread with:

  • Thread ID, source category, reviewer, location, and status.
  • Files touched.
  • What changed and why.
  • Related tests or verification commands.
  • Planned public reply, if any.
  • Resolve decision: yes/no and why.

5. Fix Bot Comments (batched)

Fix all bot comments first — these are mechanical and clearing them reduces noise before the human-comment phase.

  1. For each bot finding:
    • Read the relevant code
    • Implement the fix — ONLY the changes needed for that single finding
    • Track the files changed for this finding so the final PR reply can identify the commit that contains the fix
    • If a fix is ambiguous or would conflict with a human-comment fix already applied, mark it Needs decision and continue
  2. After all bot fixes are applied, present a summary table. Do NOT show a diff — the Edit tool already showed each change inline.
#FindingFileBotStatus
8Descriptionpath:linelinter-nameFixed
9Descriptionpath:linelinter-nameFixed
11Descriptionpath:linelinter-nameSkipped — conflicts with #3
  1. Proceed directly to Step 6.

6. Fix Human Comments (batched)

After bot fixes, work through Autofix eligible human comments in report order:

  1. State which finding you are addressing (number and one-line description)
  2. Read the relevant code and the full comment thread to understand intent
  3. Re-check eligibility before editing; if the fix is no longer clearly eligible, mark it Needs decision and continue
  4. Implement the fix — ONLY the changes needed for that single finding
  5. Track the files changed for this finding so the final PR reply can identify the commit that contains the fix
  6. If a comment needs a product/design decision, shared/public interface change, dependency, broad refactor, or has multiple reasonable fixes, mark it Needs decision and continue
  7. If the user rejects the comment instead of fixing it, record the specific rationale to use in the final PR reply

Scope Rules

  • Make the MINIMAL change that addresses the reviewer's feedback
  • Keep the diff limited to files and lines directly required by the feedback
  • First decide whether the feedback points to a local or systemic issue. Fix at the narrowest correct level; do not add a local workaround that hides a shared/root-cause bug.
  • If the feedback requires a behavior-changing code fix, add or update the directly related test in the same fix. Prefer TDD, but complete the focused red-to-green cycle before stopping: write/update the failing test, confirm it fails, implement the fix, confirm the focused test passes. Do not stop after only adding the failing test unless the user explicitly asks.
  • Do NOT rename variables, reformat code, or touch lines outside the feedback scope
  • Do NOT refactor adjacent code, even if it looks related
  • If the reviewer's comment is ambiguous, mark it Needs decision and continue with unrelated unambiguous comments
  • Do NOT create any git commits during the fix cycle. Commits are handled only in the publish step, and only with explicit user approval when needed.

7. Verify Fixes

After all fixes are applied, run the project's lint and test commands scoped to only the changed files and their directly related tests. If no code changed, skip verification and proceed to Step 8. Use safe background batches for independent validators instead of running every command sequentially.

When selecting verification commands, reuse <artifact-dir>/verification-<repo-name>.md if an artifact directory is available and the cache is fresh under the cache rules from pfleidi:pr; otherwise discover the smallest relevant lint/test/build commands. Update the cache only when an artifact directory is available.

  • Lint / static analysis — run the project's documented lint task, scoped to the files that were modified when the task supports scoping. Prefer lint-specific task wrappers such as make lint or mise run lint over invoking linter binaries directly. Do not use aggregate check, ci, or verify tasks unless you have confirmed they only run lint/static analysis. If the documented lint task cannot be scoped, run the smallest relevant project lint task.
  • Tests — run only the test files that cover the modified code (same package, same module, co-located test files). Do NOT run the full test suite.

If no project lint task exists, state that explicitly instead of assuming an unavailable linter binary.

Run formatters, generators, snapshot updates, or other mutating commands alone before validators that depend on their output. Run independent read-only validators concurrently when they do not require the same exclusive service, port, database, fixture directory, or generated output. Keep integration/e2e/service-backed commands separate unless the project documents that they are parallel-safe.

For each background batch, start every command from the same working-tree state, capture stdout/stderr/exit status from the tool, do not edit files while the batch is running, and wait for every command to finish. Run each selected validator directly, for example mise run lint, go test ..., or npm test -- .... Do not wrap validators in sh -c, shell redirection, tee, command separators, or pipelines solely to write logs; that defeats command-prefix approvals and causes extra permission prompts. If an artifact directory is available and file logs can be written after the command completes without rerunning through a shell wrapper, save them under <artifact-dir>/logs-<pr-number>-<timestamp>/; otherwise mark the full-log path as n/a. If files change after a failed batch, none of that batch's successful results count as current verification.

Show verification as a compact table:

CommandExitRelevant outputFull log
go test ./pkg/foo -run TestBar -count=10Short success excerpt.<artifact-dir>/logs-.../go-test-pkg-foo.log or n/a

For failures or short outputs, show complete output in the relevant-output column or immediately below the table. For long successful outputs, show the relevant excerpt and log path.

If lint or tests fail due to issues introduced by the fixes:

  1. Read the error output and identify every failure
  2. Fix all issues — apply the minimal changes needed
  3. Re-run the failing commands using the same safe batching rules
  4. Show the complete output again

Cap at 2 fix attempts. If still failing after 2 rounds, present the remaining failures to the user with full output.

Once verification passes, show a summary: how many comments were addressed, rejected, intentionally left unresolved, or still blocked. Do NOT show a diff — the Edit tool already showed each change inline.

Proceed to Step 8 for threads that were addressed or intentionally rejected. Leave Needs decision threads unresolved and do not reply to them unless the user provided a public rejection rationale. Do not block publishing addressed threads just because unrelated threads still need a decision.

8. Publish PR Updates

After addressed/rejected threads are ready to publish:

  1. Check branch state:

  2. If there are uncommitted fix changes, STOP and ask the user whether to commit them now or let the user commit manually. Do not push until the fixes are committed. If the user approves committing, stage only files changed for the PR feedback fixes and write the commit message from the actual diff using the subject-plus-context style from AGENTS.md.

  3. Push the committed changes for the current branch:

    If the branch has no upstream and the push fails for that reason, use:

    Never force-push.

  4. Map each addressed finding to the commit or commits that contain its fix. Use the recorded starting commit, changed-file tracking, ledger, and git log / git show to identify the relevant short SHA(s). If one commit fixes multiple comments, reference the same commit in each reply.

  5. Build and show a reply plan table before calling the API:

    ThreadStatusReply bodyResolve
    PRRT_...AddressedAddressed in abc1234 by adding the nil check before dereferencing.Yes
    PRRT_...Needs decisionn/aNo

    Proceed without asking when every actionable reply row is either addressed or a user-approved rejection. Needs decision rows with Reply = n/a and Resolve = No do not block publishing addressed threads. Stop before API calls if a rejection lacks a public rationale or if any reply body is uncertain.

  6. Reply to each original PR review thread:

    • For addressed comments, state what changed and the commit SHA(s), e.g. Addressed in abc1234 by adding the nil check before dereferencing.

    • For rejected comments, state why it was not changed, e.g. Not changed: this path already returns before allocation failure can be observed.

    • Keep replies concise but specific. Do not over-explain or repeat the diff.

    • Do not reply to comments the user explicitly chose to leave unresolved.

    • Prefer replying with the review thread ID:

      If the thread cannot be replied to by GraphQL, use the original review comment ID with the REST reply endpoint.

  7. Resolve each thread after replying:

    Do not resolve a thread that was not replied to, is still ambiguous, or still needs user approval.

  8. Present a final summary table:

    ThreadReviewerLocationStatusReplyResolved
    PRRT_...reviewerfile.go:42AddressedYesYes
    PRRT_...reviewerfile.go:99Needs decisionNoNo

    Include push result, branch, ledger path, rejected comments and rationale, and any comments intentionally left unresolved or not resolvable via API.

9. Post-Publish

  • If the user asks for adjustments, apply them
  • If the user asks to revert specific fixes, revert ONLY those changes
  • Do NOT commit or push additional changes unless explicitly asked

Fix #1 — Cursor BugBot: review-attach guard reads via Mirror

One sec. Can we talk about these issues more thoroughly?

3mo ago·10.9s

Of course. What questions do you have? I haven't applied the helper signature change yet (the call site is updated but the helper isn't, hence the compile error you just saw) — so we're at a natural pause point on #1. Let me know what you'd like to dig into.

I'm wondering if comment #1 is actually valid: We're accepting the potential for the mirror to lag behind in a bunch of situations and that's intentional because we don't want to hide errors. Why is this one special?

3mo ago·1m

Fair pushback. Let me walk through why I think this guard is materially different from the other mirror-lag-accepted sites, and then you decide.

The general "mirror lag is OK" cases share a property: failure mode is stale display.

  • entire status / entire list: mirror lags → user sees fewer checkpoints → user re-runs after the mirror catches up. No data loss.
  • Resume bootstrap, blob prefetch, doctor warning: mirror lags → operation succeeds slightly later or surfaces a fixable error.

The mirror-best-effort policy is correct for these because nothing irreversible happens — and importantly, the failures are visible to the user.

This guard is different — failure mode is silent data overwrite, not stale display.

The code path under --review with an existing HEAD checkpoint is:

  1. Outer guards (this one + the existingState.LastCheckpointID check above it) try to detect "session is already in the checkpoint."
  2. If both miss, runAttach proceeds to WriteCommitted.
  3. WriteCommitted internally calls findSessionIndex(summary, sessionID). That function returns the index of an existing session with matching SessionIDand the new write reuses that slot, overwriting the original session's metadata.

So if the guard reads via refs.Read (the v1.1 mirror) and the mirror is stale, the guard misses the existing session, WriteCommitted finds it via findSessionIndex (which reads from Primary's tree via getSessionsBranchRef), the slot is reused, and the original session's metadata is gone. Silent. No error to surface.

The guard exists specifically to convert "would silently overwrite" into "return error to user." Reading it via the lagging mirror defeats the entire purpose.

Why does WriteCommitted's internal lookup not have the same problem?

getSessionsBranchRef (in parse_tree.go, the write path) reads from s.refs.Primary, not s.refs.Read. That's deliberate: writes operate on the write target, not the read target. So findSessionIndex sees Primary's reality. The asymmetry is intentional — the read side is allowed to lag, the write side is not.

The guard is structurally a read-time check (store.ReadCommitted + store.ReadSessionMetadata), so it inherits the read-side ref by default. That's the actual bug: the guard is asking a write-side question but using a read-side API.

Precedent in this PR.

The earlier review caught the same class of issue in checkpointPresentLocally and we fixed it by constructing a Primary-bound store inline. The fix here is the same pattern. So treating this one consistently lines up with what we already did one floor down.

Counter-arguments worth taking seriously.

  • "v1.1 is internal-only; the lag window is microseconds in steady state." True. The bug is reachable but unlikely. If you're comfortable saying "the lag window is small enough that we accept the risk during the canary phase," that's a defensible position.
  • "There's still an upstream guard (existingState.LastCheckpointID)." Also true. The new guard exists for cases where session state is missing/stale, so it's not pure defense-in-depth — it's the only check for some scenarios.
  • "WriteCommitted should error instead of overwriting." That's the root-cause fix. The guard is a layered defense; the real fix would be inside WriteCommitted to never silently reuse a slot for a different write context. That's a bigger change.

My read:

The pattern is "read-side mirror lag is OK; write-side guards must not read via the mirror." This one is structurally a write-side guard. Worth fixing for consistency with the earlier review and because the failure mode is data loss, not display lag.

But it's also defensible to reject the bot's finding with rationale like "the lag window is small enough during the canary phase and the data loss is recoverable from the agent's transcript file." If that's where you land, I'll write up the public rejection.

Which way do you want to go?

Okay, fix all three comments, then

Fix #2 — push_common.go tmpRef collision

Can you re-read the CLAUDE.md file and take a look at my instructions about comments before making anymore changes?

3mo ago·56.6s

Comment trimmed to the non-obvious invariant only.

Two related cleanups before continuing — both my comments from earlier in this PR have the same issue. Want me to fix them in the same pass?

  1. attach.go:checkpointPresentLocally — mentions "e.g. v1.1 mirror" as an example. Same version-specific rot risk.
  2. committed.go:getSessionsBranchTree — docstring mentions "local-only mirror" as the case where fallback skips. Less explicit than the others; arguably accurate description of current state.

Otherwise I'll continue with fix #2 (push_common.go tmpRef collision) — that one needs no comment change, just the code fix. And fix #3 is a docstring rewrite that I'll keep version-agnostic.

xhigh effort → 5 angles × 8 candidates → 1-vote verify → sweep → ≤15 findings

You are reviewing for recall at extra-high effort: catch every real bug. At this level, catching real bugs matters more than avoiding false positives — a missed bug ships. Err on the side of surfacing.

Phase 0 — Gather the diff

Run git diff @{upstream}...HEAD (or git diff main...HEAD / git diff HEAD~1 if there's no upstream) to get the unified diff under review. If there are uncommitted changes, or the range diff is empty, also run git diff HEAD and include the working-tree changes in scope — the review often runs before the commit. If a PR number, branch name, or file path was passed as an argument, review that target instead. Treat this diff as the review scope.

Phase 1 — Find candidates (5 angles, up to 8 each)

Run 5 independent finder angles via the Agent tool. Each surfaces up to 8 candidate findings. Do NOT let one angle's conclusions suppress another's — if two angles flag the same line for different reasons, record both.

Angle A — line-by-line diff scan

Read every hunk in the diff, line by line. Then Read the enclosing function for each hunk — bugs in unchanged lines of a touched function are in scope (the PR re-exposes or fails to fix them). For every line ask: what input, state, timing, or platform makes this line wrong? Look for inverted/wrong conditions, off-by-one, null/undefined deref, missing await, falsy-zero checks, wrong-variable copy-paste, error swallowed in catch, unescaped regex metachars.

Angle B — removed-behavior auditor

For every line the diff DELETES or replaces, name the invariant or behavior it enforced, then search the new code for where that invariant is re-established. If you can't find it, that's a candidate: a removed guard, a dropped error path, a narrowed validation, a deleted test that was covering a real case.

Angle C — cross-file tracer

For each function the diff changes, find its callers (Grep for the symbol) and check whether the change breaks any call site: a new precondition, a changed return shape, a new exception, a timing/ordering dependency. Also check callees: does a parallel change in the same PR make a call unsafe?

Angle D — language-pitfall specialist

Scan for the classic pitfalls of the diff's language/framework — for example: JS falsy-zero, == coercion, closure-captured loop var; Python mutable default args, late-binding closures; Go nil-map write, range-var capture; SQL injection; timezone/DST drift; float equality. Flag any instance the diff introduces.

Angle E — wrapper/proxy correctness

When the PR adds or modifies a type that wraps another (cache, proxy, decorator, adapter): check that every method routes to the wrapped instance and not back through a registry/session/global — e.g. a caching provider holding a delegate field that resolves IDs via session.get(...) instead of delegate.get(...) will re-enter the cache or recurse. Also check that the wrapper forwards all the methods the callers actually use.

Phase 2 — Verify (1-vote, 3-state)

Dedup candidates that point at the same line/mechanism, keeping the one with the most concrete failure scenario. For each remaining candidate, run one verifier via the Agent tool: give it the diff, the relevant file(s), and the candidate, and have it return exactly one of:

  • CONFIRMED — can name the inputs/state that trigger it and the wrong output or crash. Quote the line.
  • PLAUSIBLE — mechanism is real, trigger is uncertain (timing, env, config). State what would confirm it.
  • REFUTED — factually wrong (code doesn't say that) or guarded elsewhere. Quote the line that proves it.

Keep candidates where the vote is CONFIRMED or PLAUSIBLE.

This is recall mode — a single non-REFUTED vote carries the finding. Do NOT drop on uncertainty.

Phase 3 — Sweep for gaps

Run one more finder as a fresh reviewer who has the verified list. Re-read the diff and enclosing functions looking ONLY for defects not already listed. Do not re-derive or re-confirm anything already there — the job is gaps. Focus on what the first pass tends to miss: moved/extracted code that dropped a guard or anchor; second-tier footguns (dataclass default evaluated once, hash() non-determinism, lock-scope shrink, predicate methods with side effects); setup/teardown asymmetry in tests; config defaults flipped.

Surface up to 8 additional candidates, each naming a defect not already on the list. If nothing new, return an empty sweep — do not pad.

Output

Return findings as a JSON array of at most 15 objects:

Ranked most-severe first. If more than 15 survive, keep the 15 most severe. If nothing survives verification, return [].

/simplify → 4 cleanup agents in parallel → apply the fixes

You are improving the quality of the changed code, not hunting for bugs. Review it for reuse, simplification, efficiency, and altitude issues, then fix what you find. Do not look for correctness bugs — that is what /code-review is for.

Phase 0 — Gather the diff

Run git diff @{upstream}...HEAD (or git diff main...HEAD / git diff HEAD~1 if there's no upstream) to get the unified diff under review. If there are uncommitted changes, or the range diff is empty, also run git diff HEAD and include the working-tree changes in scope — the review often runs before the commit. If a PR number, branch name, or file path was passed as an argument, review that target instead. Treat this diff as the review scope.

Phase 1 — Review (4 cleanup agents in parallel)

Launch 4 independent review agents via the Agent tool, all in a single message so they run concurrently. Pass each agent the diff and one of the four angles below. Each returns its findings with file, line, a one-line summary, and the concrete cost (what is duplicated, wasted, or harder to maintain).

Reuse

Flag new code that re-implements something the codebase already has — Grep shared/utility modules and files adjacent to the change, and name the existing helper to call instead.

Simplification

Flag unnecessary complexity the diff adds: redundant or derivable state, copy-paste with slight variation, deep nesting, dead code left behind. Name the simpler form that does the same job.

Efficiency

Flag wasted work the diff introduces: redundant computation or repeated I/O, independent operations run sequentially, blocking work added to startup or hot paths. Name the cheaper alternative.

Altitude

Check that each change is implemented at the right depth, not as a fragile bandaid. Special cases layered on shared infrastructure are a sign the fix isn't deep enough — prefer generalizing the underlying mechanism over adding special cases.

Phase 2 — Apply the fixes

Wait for all four agents to complete, dedup findings that point at the same line or mechanism, and fix each remaining one directly. Skip any finding whose fix would change intended behavior, require changes well outside the reviewed diff, or that you judge to be a false positive — note the skip rather than arguing with it. Finish with a brief summary of what was fixed and what was skipped (or confirm the code was already clean).

Summary

Fixed:

#WhatFiles
1Added CommittedRefs.PrimaryAsRead(); the two write-side guards in attach.go now use it instead of the 3-line primaryRefs := refs; primaryRefs.Read = refs.Primary; cpkg.NewGitStore(...) dance.committed_refs.go, attach.go
2Added AdvanceLocalRef(ctx, repo, refs, ref, hash); the duplicated if ref == refs.Primary { AdvanceCommittedPrimary } else { SetReference } closures in push_common.go and metadata_reconcile.go collapse to one-liners.v1_custom_ref_mirror.go, push_common.go, metadata_reconcile.go
3Added (s *GitStore) setPrimaryRef(hash); the 5 refName := s.refs.Primary; SetReference; Errorf write sites in committed.go collapse.store.go, committed.go
4+5Split mirror into setMirrorTo(refs, hash) (known hash) and MirrorCommittedMetadataRef (reads Primary first). AdvanceCommittedPrimary uses the known-hash path via the new setMirrorToBestEffort — saves one repo.Reference lookup on every committed write. Also moved HasMirror guard above WithoutCancel.v1_custom_ref_mirror.go
6Replaced redundant ResolveCommittedRefs(ctx) calls with store.Refs() at the 4 sites where a store already exists: condensation finalize, attribution finalize, transcript finalize, explain getBranchCheckpoints temp-checkpoint lookup. Each call was a settings.Load disk hit + git subprocess.manual_commit_condensation.go, manual_commit_hooks.go, explain.go
7Replaced hand-built v1-only CommittedRefs literal in test with checkpoint.DefaultV1Refs().v1_custom_ref_mirror_test.go

Skipped (with reasons in the planning table above): findings whose fixes would undo refactor design intent (refDisplayName dead else, advance single-branch), came from main rather than this PR (MirrorPrimaryMissing label), or were too invasive for /simplify scope (threading refs through explain --generate chain, WriteCommitted returning hash, checkpointHasSessionMetadata N+1 cleanup).

Verification: build, vet, mise run lint (0 issues), focused tests on checkpoint/..., strategy/..., and TestAttach|TestExplain in cmd/entire/cli/ — all green. Pre-existing TestRunAuthStatus_RendersSessionsTable (date-dependent, came in via the merge) still fails; unrelated.

Diff: 11 files changed, +90 / -81. Net structural simplification with the new helpers absorbing ~25 lines of duplicated patterns. Changes uncommitted, ready for review.

PR Feedback

1. Identify the PR

If the user provided a PR number or URL, use that. Otherwise, detect from the current branch:

If no PR exists for the current branch, stop and tell the user.

2. Fetch Review Comments

Fetch PR metadata first so comment decisions have intent context:

Also collect branch commits and changed files for context:

Show the PR context as a table before classifying comments:

ContextSourceValue
PRtitle/bodyOne-line PR intent
BranchcommitsOne-line commit summary
Changed surfacediff file listMain packages/files touched
Base/headPR metadatabase <- head

Fetch unresolved review threads with GraphQL as the primary source of truth. Group work by thread, not by individual REST comment:

Filter to unresolved threads only. If there are no unresolved threads, report that to the user and stop — there is nothing to fix.

If GraphQL pagination indicates more review threads or thread comments are available, paginate before classifying. Do not classify a partial thread set as complete.

Use REST pull-review comments only as a fallback when GraphQL data is incomplete or a thread cannot be mapped to a review comment ID:

When REST fallback is used, deduplicate by GraphQL thread ID first, then by file/line/body/author. Do not present or fix the same review request twice.

3. Parse, Classify, and Group

Use permission-friendly reads while investigating comments. Avoid shell pipelines, command separators, subshells, and output filters for read-only source inspection because they create extra permission prompts and can block background work. Do not run commands like git show HEAD:path | sed -n '10,40p'. Use workspace file range reads, rg with path limits, path-scoped diffs, or one standalone git show <rev>:<path> only when the output is acceptably small.

For each comment, extract:

  • Author — who left it
  • Author type — bot, automated reviewer, human reviewer, or maintainer
  • File and line — where it points
  • Body — the actual feedback (verbatim, not paraphrased)
  • Thread context — any replies in the same thread (to understand if it was already discussed or resolved conversationally)
  • Thread ID and comment ID — the GraphQL review thread ID and original comment ID needed to reply and resolve

Group each unresolved review thread into a single finding. If multiple comments in one thread refine or supersede each other, use the latest unresolved reviewer request as the finding and retain the earlier messages as context.

Classify each finding source:

  • Bot — GitHub bot, CI system, or linter/static-analysis account such as github-actions[bot] or codecov[bot]
  • Automated reviewer — review-assistant accounts that produce natural-language suggestions, such as Copilot or CodeRabbit
  • Human reviewer — non-bot reviewer
  • Maintainer — repository owner/member/maintainer when that can be inferred from GitHub metadata

4. Present Findings

Present two separate sections:

Human Comments

Table ordered by:

  1. Bugs / correctness issues — reviewer identified broken logic or missing error handling
  2. Design / architecture feedback — structural changes, API shape, naming of public interfaces
  3. Style / nits — formatting, naming of local variables, minor readability

Use this table format:

#PriorityLocationReviewerRequestKey quoteAutofix
1Bugfile.go:42reviewerOne-line summary of what the reviewer is asking for.Short verbatim excerpt.Eligible, or Needs decision with the exact decision needed.

For automated reviewers, use the same table and set Reviewer to the tool account, with Priority based on the substance of the request.

Bot Comments (batched)

Table continuing the numbering from above, grouped by tool/bot:

#BotLocationRequired fixAutofix
8linter-namefile.go:42One-line summary of the required fix.Eligible, or Needs decision with the exact decision needed.

Keep table cells short and scannable. Use the smallest useful verbatim quote, not the full comment body. Escape | characters inside code or text so the table remains valid Markdown.

End with a summary: total human comments, total bot comments, overall assessment of effort.

Do not stop for mode selection. Proceed by default with bot comments and human comments marked Autofix eligible. Mark a human comment Autofix eligible only when the requested change is source-backed, high confidence, minimal, unambiguous, does not require a product/design decision, does not add a dependency, does not change a shared/public interface, and has a clear verification path.

Leave all other human comments unresolved as Needs decision, with the exact decision needed. Do not reject a reviewer comment by default; rejection requires a user-provided public rationale.

Before applying any fixes, record the starting commit:

Choose an artifact directory using the AGENTS.md temporary artifact rule with agent name pfleidi-pr-feedback:

  • Use ./tmp/pfleidi-pr-feedback/ only when ./tmp/ already exists and is already ignored.
  • If no project-local artifact directory is available, do not create file artifacts by default; keep ledger/log/cache information in the response and mark file paths n/a. Ask before using /tmp/pfleidi-pr-feedback/ or modifying ignore files.

When an artifact directory is available, create a temporary thread ledger at <artifact-dir>/pr-feedback-<pr-number>.md. If no artifact directory is available, keep the same ledger fields in the final summary table instead. Update the ledger after each thread with:

  • Thread ID, source category, reviewer, location, and status.
  • Files touched.
  • What changed and why.
  • Related tests or verification commands.
  • Planned public reply, if any.
  • Resolve decision: yes/no and why.

5. Fix Bot Comments (batched)

Fix all bot comments first — these are mechanical and clearing them reduces noise before the human-comment phase.

  1. For each bot finding:
    • Read the relevant code
    • Implement the fix — ONLY the changes needed for that single finding
    • Track the files changed for this finding so the final PR reply can identify the commit that contains the fix
    • If a fix is ambiguous or would conflict with a human-comment fix already applied, mark it Needs decision and continue
  2. After all bot fixes are applied, present a summary table. Do NOT show a diff — the Edit tool already showed each change inline.
#FindingFileBotStatus
8Descriptionpath:linelinter-nameFixed
9Descriptionpath:linelinter-nameFixed
11Descriptionpath:linelinter-nameSkipped — conflicts with #3
  1. Proceed directly to Step 6.

6. Fix Human Comments (batched)

After bot fixes, work through Autofix eligible human comments in report order:

  1. State which finding you are addressing (number and one-line description)
  2. Read the relevant code and the full comment thread to understand intent
  3. Re-check eligibility before editing; if the fix is no longer clearly eligible, mark it Needs decision and continue
  4. Implement the fix — ONLY the changes needed for that single finding
  5. Track the files changed for this finding so the final PR reply can identify the commit that contains the fix
  6. If a comment needs a product/design decision, shared/public interface change, dependency, broad refactor, or has multiple reasonable fixes, mark it Needs decision and continue
  7. If the user rejects the comment instead of fixing it, record the specific rationale to use in the final PR reply

Scope Rules

  • Make the MINIMAL change that addresses the reviewer's feedback
  • Keep the diff limited to files and lines directly required by the feedback
  • First decide whether the feedback points to a local or systemic issue. Fix at the narrowest correct level; do not add a local workaround that hides a shared/root-cause bug.
  • If the feedback requires a behavior-changing code fix, add or update the directly related test in the same fix. Prefer TDD, but complete the focused red-to-green cycle before stopping: write/update the failing test, confirm it fails, implement the fix, confirm the focused test passes. Do not stop after only adding the failing test unless the user explicitly asks.
  • Do NOT rename variables, reformat code, or touch lines outside the feedback scope
  • Do NOT refactor adjacent code, even if it looks related
  • If the reviewer's comment is ambiguous, mark it Needs decision and continue with unrelated unambiguous comments
  • Do NOT create any git commits during the fix cycle. Commits are handled only in the publish step, and only with explicit user approval when needed.

7. Verify Fixes

After all fixes are applied, run the project's lint and test commands scoped to only the changed files and their directly related tests. If no code changed, skip verification and proceed to Step 8. Use safe background batches for independent validators instead of running every command sequentially.

When selecting verification commands, reuse <artifact-dir>/verification-<repo-name>.md if an artifact directory is available and the cache is fresh under the cache rules from pfleidi:pr; otherwise discover the smallest relevant lint/test/build commands. Update the cache only when an artifact directory is available.

  • Lint / static analysis — run the project's documented lint task, scoped to the files that were modified when the task supports scoping. Prefer lint-specific task wrappers such as make lint or mise run lint over invoking linter binaries directly. Do not use aggregate check, ci, or verify tasks unless you have confirmed they only run lint/static analysis. If the documented lint task cannot be scoped, run the smallest relevant project lint task.
  • Tests — run only the test files that cover the modified code (same package, same module, co-located test files). Do NOT run the full test suite.

If no project lint task exists, state that explicitly instead of assuming an unavailable linter binary.

Run formatters, generators, snapshot updates, or other mutating commands alone before validators that depend on their output. Run independent read-only validators concurrently when they do not require the same exclusive service, port, database, fixture directory, or generated output. Keep integration/e2e/service-backed commands separate unless the project documents that they are parallel-safe.

For each background batch, start every command from the same working-tree state, capture stdout/stderr/exit status from the tool, do not edit files while the batch is running, and wait for every command to finish. Run each selected validator directly, for example mise run lint, go test ..., or npm test -- .... Do not wrap validators in sh -c, shell redirection, tee, command separators, or pipelines solely to write logs; that defeats command-prefix approvals and causes extra permission prompts. If an artifact directory is available and file logs can be written after the command completes without rerunning through a shell wrapper, save them under <artifact-dir>/logs-<pr-number>-<timestamp>/; otherwise mark the full-log path as n/a. If files change after a failed batch, none of that batch's successful results count as current verification.

Show verification as a compact table:

CommandExitRelevant outputFull log
go test ./pkg/foo -run TestBar -count=10Short success excerpt.<artifact-dir>/logs-.../go-test-pkg-foo.log or n/a

For failures or short outputs, show complete output in the relevant-output column or immediately below the table. For long successful outputs, show the relevant excerpt and log path.

If lint or tests fail due to issues introduced by the fixes:

  1. Read the error output and identify every failure
  2. Fix all issues — apply the minimal changes needed
  3. Re-run the failing commands using the same safe batching rules
  4. Show the complete output again

Cap at 2 fix attempts. If still failing after 2 rounds, present the remaining failures to the user with full output.

Once verification passes, show a summary: how many comments were addressed, rejected, intentionally left unresolved, or still blocked. Do NOT show a diff — the Edit tool already showed each change inline.

Proceed to Step 8 for threads that were addressed or intentionally rejected. Leave Needs decision threads unresolved and do not reply to them unless the user provided a public rejection rationale. Do not block publishing addressed threads just because unrelated threads still need a decision.

8. Publish PR Updates

After addressed/rejected threads are ready to publish:

  1. Check branch state:

  2. If there are uncommitted fix changes, STOP and ask the user whether to commit them now or let the user commit manually. Do not push until the fixes are committed. If the user approves committing, stage only files changed for the PR feedback fixes and write the commit message from the actual diff using the subject-plus-context style from AGENTS.md.

  3. Push the committed changes for the current branch:

    If the branch has no upstream and the push fails for that reason, use:

    Never force-push.

  4. Map each addressed finding to the commit or commits that contain its fix. Use the recorded starting commit, changed-file tracking, ledger, and git log / git show to identify the relevant short SHA(s). If one commit fixes multiple comments, reference the same commit in each reply.

  5. Build and show a reply plan table before calling the API:

    ThreadStatusReply bodyResolve
    PRRT_...AddressedAddressed in abc1234 by adding the nil check before dereferencing.Yes
    PRRT_...Needs decisionn/aNo

    Proceed without asking when every actionable reply row is either addressed or a user-approved rejection. Needs decision rows with Reply = n/a and Resolve = No do not block publishing addressed threads. Stop before API calls if a rejection lacks a public rationale or if any reply body is uncertain.

  6. Reply to each original PR review thread:

    • For addressed comments, state what changed and the commit SHA(s), e.g. Addressed in abc1234 by adding the nil check before dereferencing.

    • For rejected comments, state why it was not changed, e.g. Not changed: this path already returns before allocation failure can be observed.

    • Keep replies concise but specific. Do not over-explain or repeat the diff.

    • Do not reply to comments the user explicitly chose to leave unresolved.

    • Prefer replying with the review thread ID:

      If the thread cannot be replied to by GraphQL, use the original review comment ID with the REST reply endpoint.

  7. Resolve each thread after replying:

    Do not resolve a thread that was not replied to, is still ambiguous, or still needs user approval.

  8. Present a final summary table:

    ThreadReviewerLocationStatusReplyResolved
    PRRT_...reviewerfile.go:42AddressedYesYes
    PRRT_...reviewerfile.go:99Needs decisionNoNo

    Include push result, branch, ledger path, rejected comments and rationale, and any comments intentionally left unresolved or not resolvable via API.

9. Post-Publish

  • If the user asks for adjustments, apply them
  • If the user asks to revert specific fixes, revert ONLY those changes
  • Do NOT commit or push additional changes unless explicitly asked
