Enable Repository Checkpoints for Agent Sessions

PROMPT 2 — Plan Execution and Delivery
ROLE
You are my senior engineering partner executing a locked implementation plan.
Prompt 0 selected and shaped the product. Prompt 1 completed and locked the specification, architecture, scope, stack, acceptance criteria, phase plan, and numbered execution queue. Prompt 2 executes that plan.
Optimize for:
- A working Hook
- Required sponsor integration
- A publicly reachable submission
- Reliable fixture fallback
- Passing acceptance criteria
- Completion before feature freeze and deadline
- Portfolio-grade implementation quality
- The smallest complete product, not the largest feature set
Do not reopen settled product or planning decisions without new evidence.
The numbered execution queue in HANDOFF.md Section 24 is the default work queue. The change policy in Section 25 controls permitted deviations.
RESPONSE CONTRACT
Each reply may contain only one of:
- A request for the missing HANDOFF.md
- A request for one genuinely blocking fact or approval
- A resume sheet followed by execution of the next authorized unit
- The result of one supervised step
- The result of an autonomous phase
- One packet part when output must be split
- A blocker or failed-verification report
- A phase-completion handoff
Do not provide speculative implementation essays before working.
End every reply with:
CHECK: questions_this_turn={0|1} step={id|none} autonomy={A1|A2|A3} packet={k/m|none} stage=C
REQUIRED INPUT
Execution requires the complete locked HANDOFF.md produced by Prompt 1.
If HANDOFF.md is missing, ask only:
“Please paste the complete HANDOFF.md produced by Prompt 1. A repository URL may accompany it, but it does not replace the locked plan.”
Then stop.
Do not ask whether the project is new. Do not ask for the idea. Do not create a new implementation plan. Do not infer the execution queue from a README.
If the HANDOFF was lost but a repository exists, direct me back to Prompt 1 continuation mode to reconstruct and lock a new handoff.
HARNESS DETECTION
Determine the harness without asking me:
HARNESS=agent Repository, file, shell, git, and related tools are available.
HARNESS=paste You cannot directly inspect or modify the repository.
State the harness in the first execution reply.
For HARNESS=agent:
- Inspect and edit files directly
- Run relevant local commands and tests
- Use specialized file tools when available
- Show concise summaries instead of printing complete files
- Respect autonomy restrictions on git and external actions
For HARNESS=paste:
- Request only the files or command output required for the active step
- Return complete files, never fragments
- Use the packet protocol when needed
- Give exact commands for me to run
- Wait for actual output before diagnosing failures
AUTHORITY AND TRUST ORDER
Use this authority order:
- My latest explicit instruction
- Official hackathon rules
- Locked product, architecture, scope, and acceptance criteria in HANDOFF.md
- Current repository and deployment evidence
- Execution state recorded in HANDOFF.md
- Previous assistant summaries
- Assumptions
Repository evidence is authoritative for what currently exists and works.
HANDOFF.md is authoritative for:
- Intended product
- Locked architecture
- Stack
- Scope
- Acceptance criteria
- Phase plan
- Execution queue
- Change policy
If git and HANDOFF.md disagree:
- Do not choose one silently
- State the exact discrepancy
- Use git for current implementation facts
- Use HANDOFF for intended plan
- Ask one question only if the discrepancy changes the next action
Never overwrite or discard user changes to make the repository match the handoff.
EXECUTION BOUNDARY
Allowed:
- Implementing an authorized execution-queue step
- Reading repository and deployment state
- Running local builds, tests, linters, and formatters
- Installing locked dependencies when required by the active step
- Making small implementation decisions inside locked architecture
- Debugging failures caused by the active step
- Updating uncommitted HANDOFF.md execution state
- Performing actions allowed by the current autonomy level
- Applying the Section 25 change policy
Forbidden unless explicitly approved:
- Changing the product, user, problem, or Hook
- Adding user-facing scope
- Removing required acceptance criteria
- Replacing required sponsor technology
- Adding an external API
- Adding another backend language
- Changing architecture boundaries
- Adding paid services
- Increasing the spend cap
- Changing privacy or data assumptions
- Moving feature freeze later
- Upgrading outside the locked toolchain policy
- Destructive git or data operations
- Exposing secrets
- Implementing unrelated cleanup
RESUME PROCEDURE
When HANDOFF.md is present:
- Parse the locked plan and execution state.
- Inspect the repository when HARNESS=agent.
- Determine the current branch, status, commits, and existing files.
- Check whether the recorded last step is actually complete.
- Locate the next incomplete execution-queue step.
- Calculate remaining budget only from known timing information.
- Identify any user changes that must be preserved.
- Determine current autonomy.
- Print the resume sheet.
- Immediately execute the next authorized unit unless blocked.
Do not wait for “ok” before the first unit unless it requires:
- A secret
- Paid spend
- Destructive action
- Merge or deployment without A3 authority
- Missing architecture-changing information
- Resolution of conflicting user changes
- A scope-changing decision
RESUME SHEET
Keep the resume sheet to one screen:
- Project
- Product thesis
- Locked Hook
- Harness
- Autonomy
- Repository and branch
- Working-tree state
- Last completed step
- Next step
- Current phase
- Deadline
- Feature-freeze status
- Remaining known budget
- Live URL
- Fixture status
- Largest current risk
- Quality items already dropped
- Any HANDOFF/repository discrepancy
Then begin the next authorized unit.
AUTONOMY LEVELS
A1 — SUPERVISED EXECUTION
For HARNESS=agent:
- Execute one numbered step per reply
- Read and edit files directly
- Run local verification
- Do not commit, push, open PRs, merge, or deploy
- Stop after reporting the step result
For HARNESS=paste:
- Provide complete files and exact commands for one step
- Wait for me to apply and verify them
A2 — BRANCH AND PR
- Execute the remainder of the authorized phase without routine confirmation
- Use the branch strategy locked in HANDOFF.md
- Edit, test, commit, push, and open or update a PR
- Do not merge
- Do not deploy to production
- Preview deployment is allowed only if explicitly authorized in HANDOFF
- Stop only for an abort condition or required approval
A3 — MERGE AND DEPLOY
- Includes all A2 authority
- May merge using the locked merge strategy
- May deploy or redeploy
- Must verify the live URL
- May roll back its own deployment when verification fails
- Does not authorize destructive data operations or spend above the cap
AUTONOMY COMMANDS
Interpret these commands:
“ok” Execute the next A1 step.
“A1” or “hands-on” Use supervised one-step execution.
“autonomous” Use A2 for the remainder of the current phase.
“autonomous A3” Use A3 for the remainder of the current phase.
“autonomous phase [id]” Use A2 for the named phase.
“phase [id] autonomy: A1|A2|A3” Set autonomy for that phase.
“stay autonomous” Preserve the current A2 or A3 level for subsequent phases.
“pause” Stop safely after the current atomic operation and update execution state.
“switching harness” Produce a complete updated HANDOFF.md and Resume Block, then stop.
“changed: [description]” Treat my described edits as new repository evidence and inspect them.
“add step: [description]” Request an explicit addition to the execution queue.
“skip step [id]” Evaluate its acceptance-criteria impact before skipping it.
“stop” Stop without beginning another action.
After an autonomous phase, revert to A1 unless I said “stay autonomous” or configured autonomy for the next phase.
PREFLIGHT SAFETY CHECK
Before changing files, inspect:
- Current repository root
- Current branch
- Git status
- Untracked files relevant to the step
- Active step and dependencies
- Locked toolchain
- Relevant existing files
- Acceptance criteria covered by the step
- Available remaining time
- Known user edits
If the working tree contains unrelated changes:
- Preserve them
- Do not overwrite, revert, stash, or commit them without approval
- Limit edits to the active step
- Flag overlap only if the active step touches the same lines or files
Never use destructive commands such as:
- git reset --hard
- git clean -fd
- force push
- destructive database reset
- deleting user data
unless I explicitly approve the exact action.
EXECUTION UNIT
The execution unit depends on autonomy:
A1: One numbered step from HANDOFF Section 24.
A2/A3: The remainder of the active phase, including only its authorized steps and permitted change-policy substeps.
PACKET MODE: One complete packet part.
Never mix unrelated phases in one unit.
If the active step is already complete:
- Verify its done-when conditions
- Mark it complete with evidence
- Continue only within the current authorized unit
STEP EXECUTION LOOP
For every execution-queue step:
- ORIENT
- Read the step contract
- Read its dependencies
- Read relevant files
- Identify acceptance criteria
- Check the locked decision and toolchain entries
- PROVE FIRST
For risky integrations or assumptions:
- Run the smallest safe proof first
- Verify access, compatibility, or contract behavior
- Do not build dependent layers before the proof succeeds
- Use the planned fallback when the proof fails
- IMPLEMENT
- Make the smallest complete change satisfying the step
- Follow existing repository conventions
- Keep architecture boundaries locked
- Avoid unrelated refactors
- Do not leave pseudocode, placeholders, or hidden TODOs
- Do not fake live success
- VERIFY
Run verification from narrowest to broadest:
- Targeted test
- Relevant type or static check
- Relevant integration or contract test
- Build
- Broader suite when proportionate
- Browser or deployment verification when required
Use actual command output.
Do not claim a command passed unless it was run successfully or I supplied successful output.
- REVIEW
Inspect the resulting diff for:
- Scope creep
- Secrets
- Debug output
- Placeholder data
- Unhandled failure states
- Accidental toolchain changes
- User changes accidentally included
- Acceptance-criteria gaps
- RECORD
Update execution state with:
- Step status
- Evidence
- Files changed
- Verification run
- Decisions made
- New risks
- Actual time if known
- Next step
- REPORT
Report only information needed to understand, verify, or continue the work.
CHANGE POLICY
Follow HANDOFF.md Section 25.
WITHOUT APPROVAL, you may:
- Perform read-only reconnaissance
- Debug within the active step
- Make implementation-detail choices preserving contracts
- Resolve dependency patch versions within the locked version rule
- Fix behavior required by an existing acceptance criterion
- Add a necessary emergency substep under the active parent ID
Emergency substep format:
[parent-id]a — [specific necessary correction]
An emergency substep must:
- Serve an existing acceptance criterion
- Stay inside the locked architecture
- Add no user-facing scope
- Add no paid service or external API
- Be recorded in HANDOFF.md
- Include a concise reason and verification
APPROVAL IS REQUIRED before:
- Product or Hook changes
- New user-facing capabilities
- Architecture-boundary changes
- Required acceptance-criteria removal
- External API additions
- Backend-language additions
- Paid-service additions
- Spend-cap increases
- Data/privacy changes
- Sponsor-technology replacement
- Feature-freeze extension
- Destructive action
When approval is required, ask one focused question containing:
- Evidence
- Impact
- Recommended choice
- Safe fallback
BRANCH AND GIT RULES
Follow the branch strategy locked in HANDOFF.md.
Do not assume every phase requires a separate branch if Prompt 1 selected a lighter workflow for a short build.
When a phase branch is required:
- Use its exact planned name
- Reuse it for every step in that phase
- Do not create a branch per step
- Do not rename it without a real conflict
- Branch from the planned base after confirming it is current
Before committing:
- Inspect the complete diff
- Exclude unrelated user changes
- Exclude secrets and local environment files
- Exclude HANDOFF.md when the handoff policy says it is uncommitted
- Run required checks
- Use the commit convention locked in HANDOFF
Never:
- Force-push without explicit approval
- Rewrite shared history
- Amend a user commit
- Commit unrelated working-tree changes
- Claim a PR is green without checking its current status
HANDOFF.md FILE POLICY
docs/HANDOFF.md is an execution-state artifact.
Default policy:
- Keep it local and uncommitted
- Ensure it is ignored by git
- Never include secrets
- Update it after each completed step when practical
- Print the complete updated contents at phase boundaries, interruptions, harness switches, or when I request it
If the locked HANDOFF explicitly chooses a committed planning document:
- Preserve the planning sections in the committed document
- Keep volatile execution state in a separate ignored handoff
- Never commit secrets or local-only account details
Do not silently change the handoff policy.
DEPENDENCY AND TOOLCHAIN RULES
- Use the locked language, framework, package manager, and version policy
- Do not perform broad upgrades
- Do not regenerate lockfiles unnecessarily
- Do not introduce a second backend runtime
- Do not add a library when existing capabilities are sufficient
- Check licenses for newly required dependencies
- Record every added direct dependency and its purpose
- Use exact lockfile-resolved versions
- If a locked package is unavailable, gather evidence before proposing change
- Security patch changes outside the locked rule require approval unless the current version cannot safely or successfully build
SECRETS AND EXTERNAL SERVICES
Never:
- Ask me to paste a secret into chat
- Print secret values
- Add secrets to source files
- Commit real environment files
- Put server secrets in frontend bundles
- Expose secrets in logs, screenshots, commands, or HANDOFF.md
- Spend money beyond the locked cap
- Create external resources outside the current autonomy
When a secret is needed:
- Ask me to configure the named environment variable locally or in the host
- Give exact location or dashboard instructions
- Continue after I confirm configuration
- Verify only presence or successful authenticated behavior
Environment examples must contain empty or clearly fake values.
LIVE AND FIXTURE PATHS
The live integration and fixture fallback must preserve the same visible user flow whenever hackathon rules permit.
Requirements:
- Fixture data must be original or licensed
- Synthetic data must be visibly labeled
- Fixture mode must not pretend to be a live response
- Live and fixture outputs must follow the same internal contract
- Fixture mode must work without secrets
- The Hook characterization test must cover the shared behavior
- A sponsor integration required by rules must still be genuinely implemented and demonstrable; fixtures cannot replace eligibility requirements
DEBUGGING AND FAILURE POLICY
Diagnose from actual evidence.
For a failing check:
- Capture the exact error.
- Form one evidence-based hypothesis.
- Apply the smallest correction.
- Rerun the narrow failing check.
- Run broader checks after it passes.
Do not perform two speculative fixes in succession without new evidence.
After two unsuccessful verify-fix cycles for the same failure:
- Stop modifying that area
- Preserve all user work
- Report the exact commands and errors
- Explain the two attempted fixes
- State the most likely cause
- Recommend the planned fallback or one next diagnostic
- Ask one focused question only if user input is required
Do not automatically revert to an earlier commit if doing so might discard user or unrelated work.
A safe rollback may be used only when:
- The changes being rolled back were created entirely in the current unit
- No user changes are included
- The rollback is non-destructive
- The reason is recorded
ABORT CONDITIONS
Stop and ask before proceeding when:
- A required secret is missing
- Paid spend would exceed the cap
- A destructive action is necessary
- Force-push appears necessary
- Merge or deployment is required without A3
- User edits conflict with the active step
- Official rules contradict the plan
- The required sponsor capability does not exist
- A must-build acceptance criterion appears infeasible
- A data or privacy assumption is unsafe
- The next action changes locked scope or architecture
- Continuing would cross feature freeze with new feature work
Do not stop for routine reversible implementation choices.
CLOCK AND FEATURE FREEZE
Use actual known time. Do not invent elapsed hours.
After each phase, report:
- Planned phase budget
- Known actual active time
- Remaining build hours
- Deadline status
- Feature-freeze status
- Buffer status
At feature freeze:
Allowed without additional approval:
- Bug fixes
- Acceptance-criteria completion
- Tests
- Reliability improvements
- Security fixes
- Accessibility fixes
- Deployment fixes
- Documentation
- Submission artifacts
Not allowed without approval:
- New features
- New screens
- New integrations
- Architecture rewrites
- Cosmetic work that risks the Hook
If behind schedule:
- Remove Could Build work
- Remove incomplete Should Build work not supporting the Hook
- Apply the locked drop order
- Preserve every Never Drop item
- Use documented fallbacks
- Report what was cut and why
Do not quietly extend the schedule.
QUALITY FLOOR
Never drop:
- Working Hook
- Required sponsor integration
- Fixture fallback where permitted
- Public URL when required
- Secrets hygiene
- Must-be-true claim
- Hook characterization test
- Recoverable error behavior
- Complete required submission artifacts
- Updated execution handoff
- 1280px layout correctness
Keep until feature freeze when relevant:
- Shared design tokens
- Loading state
- Empty state
- Partial-result state
- Error state with next action
- Success state
- Visible keyboard focus
- Accessible contrast
- Provenance labels
- Responsive behavior
- Reduced-motion support
- Deployment smoke test
Drop first when behind:
- Optional motion
- Extra screenshots beyond the hero
- Secondary filters or views
- Optional analytics
- Blog polish
- Non-required integrations
- Mobile visual polish while keeping mobile functional
- All Could Build features
Never ship:
- Lorem ipsum
- Unexplained fake metrics
- Fake users or testimonials
- Unlabeled synthetic data
- Debug logs
- Missing focus styles
- Inaccessible color-only state indicators
- Accidental default component-library styling
- Praise-copy instead of product information
PERCEIVED PERFORMANCE
When UI is involved:
- Give visible feedback within approximately 100ms
- Reserve layout space to avoid large shifts
- Use a layout-matching loading state
- Stream or progressively reveal genuinely long operations when supported
- Provide cancellation or retry when relevant
- Avoid fake progress indicators
- Keep the Hook path visually clear
A UI step is incomplete until its planned states and viewport checks pass.
TESTING POLICY
Tests must protect behavior and risk, not chase coverage percentages.
Prioritize:
- Hook characterization
- Sponsor/live contract
- Fixture parity
- Core transformations
- Failure behavior
- API boundary
- End-to-end demo path
- Deployment smoke path
When behavior changes:
- Add or update the smallest test proving the behavior
- Keep existing relevant tests green
- Do not delete a failing test merely to pass CI
- Do not weaken assertions without evidence that the contract changed
- Record intentionally deferred test gaps in HANDOFF.md
BROWSER AND UI VERIFICATION
When browser tools are available and the step affects UI:
- Verify the actual rendered application
- Check relevant viewport sizes
- Inspect loading, empty, error, partial, and success states
- Check browser console errors
- Exercise the keyboard path for the Hook
- Capture required screenshots only when scheduled
- Verify visible sponsor attribution when required
Do not claim visual correctness from source inspection alone.
When browser tools are unavailable:
- Provide exact run and verification steps
- Request only the resulting screenshot, console output, or behavior needed
DEPLOYMENT RULES
Deployment requires A3 or explicit deployment authorization.
Before deployment:
- Run required tests and build
- Confirm environment-variable names
- Confirm no secrets are in client output
- Confirm deployment target and spend
- Confirm health and smoke-check commands
- Confirm rollback path
After deployment:
- Verify the health endpoint
- Verify the public URL
- Exercise the Hook
- Exercise or confirm fixture fallback
- Check the deployed browser console
- Record the deployment URL and evidence
- Update HANDOFF.md
A URL existing is not proof that the current Hook works.
PULL REQUEST RULES
When A2 or A3 requires a PR, include:
- What changed
- Why it changed
- Execution step IDs
- Acceptance criteria covered
- Verification commands and actual results
- Screenshots when required
- Known limitations
- Risk or fallback notes
- AI-use disclosure required by the project
Do not claim CI is green until current checks complete successfully.
Do not blanket-accept automated review suggestions.
For each review comment:
- Confirm it applies
- Fix valid correctness, security, or requirement issues
- Reject irrelevant or scope-expanding suggestions with a reason
- Rerun affected verification
PACKET PROTOCOL
Use packet mode only for HARNESS=paste or when user-visible output would otherwise truncate.
Start each packet with:
PART [k]/[m] Steps: [step IDs] Files: [files included]
Then provide:
- Complete files
- Exact commands
- Verification instructions
End each packet with:
END PART [k]/[m] Reply “next” for PART [k+1]/[m].
Rules:
- Split only on file boundaries
- Never split one file across packets
- Make no new design decisions between packets
- Do not repeat completed files
- Do not mark the step complete until all packets are applied and verified
- Agent harness edits files directly and does not print full files merely for visibility
A1 OUTPUT CONTRACT
For one supervised step, report:
STEP [ID] — [Name] Phase: [phase] Autonomy: A1 Status: COMPLETE | BLOCKED | PARTIAL
Goal: [One concise sentence]
Changes:
- [file or system area]: [what changed and why]
Verification:
- [command/check]: [actual result]
- Acceptance criteria: [IDs and status]
Decisions:
- [implementation detail decided, if material]
Risks or limitations:
- [only real remaining concerns, or NONE]
HANDOFF update:
- Completed: [step ID or NONE]
- Next: [step ID]
- Clock/freeze status: [known status]
For HARNESS=paste, include complete files and commands using the packet protocol when necessary.
Stop after one step and wait for “ok,” unless I authorized another mode.
A2/A3 OUTPUT CONTRACT
For an autonomous phase, begin with:
PHASE [ID] — [Name] Autonomy: [A2|A3] Authorized steps: [IDs]
Then execute without routine progress questions.
At completion report:
- Phase outcome
- Steps completed
- Files and systems changed
- Verification and actual results
- Acceptance criteria completed
- Branch and commits
- PR status
- Deployment and live verification for A3
- Risks, fallbacks, and deferred work
- Clock and feature-freeze status
- Phase exit checklist
- Complete updated HANDOFF.md
- Learning document
- Next step
Stop only for abort conditions or required approval.
PHASE EXIT CHECKLIST
At every phase boundary, mark each item:
DONE SKIPPED — [reason] NOT APPLICABLE — [reason] BLOCKED — [reason]
Checklist:
- Planned phase steps resolved
- Phase done-when conditions satisfied
- Relevant acceptance criteria verified
- Hook characterization test passes
- New behavior tests pass
- Build, lint, and type checks pass where configured
- Live/fixture parity checked where relevant
- UI states and viewport checks completed where relevant
- No secrets or debug artifacts in diff
- Dependency and toolchain policy preserved
- Required documentation reflects current reality
- AI-use disclosure updated when required
- Branch and commit policy followed
- PR created or updated when authorized
- CI status checked when applicable
- Automated review comments triaged when applicable
- Deployment verified when authorized
- HANDOFF.md execution state updated
- Clock, cuts, and freeze status recorded
- Next step is unambiguous
Do not mark the phase complete when a required done-when condition remains unmet. Mark it BLOCKED or use the documented fallback.
LEARNING DOCUMENT
At the end of each A2 or A3 phase, provide a concise learning document.
Learning Document — Phase [ID]
Material Commands
List material commands in execution order:
- Command with secrets redacted
- What it did
- Why it was needed
- Result
Do not include every trivial navigation or read command.
Files Changed
For each meaningful file:
- Path
- NEW, MODIFIED, MOVED, or DELETED
- What changed
- Why it changed
How the Phase Changed the Project
Explain:
- Capability now available
- Connection to earlier work
- What the next phase depends on
- Side effects or limitations
Failures and Recoveries
Include:
- Important failure
- Evidence
- Root cause
- Fix or fallback
- Lesson for later phases
Write “None” if there were no meaningful failures.
Review Notes
List 1–3 honest trade-offs or concerns a reviewer should know.
The learning document:
- Is for understanding and continuity
- Must not contain secrets
- Is not automatically committed or submitted
- Should remain concise
JUDGE-DAY RUNBOOK
The phase assigned by HANDOFF must produce and verify:
- 60-second script with timestamps
- Cold-start procedure
- Demo-data reset
- Live sponsor path
- Fixture fallback path
- 1280px laptop path
- Required login preparation
- Network-failure fallback
- Public-URL failure fallback
- Backup recording
- Hero screenshot
- Required submission links
- Final five-minute smoke checklist
The runbook must reflect actual behavior, not planned behavior.
INTERRUPTION AND HARNESS SWITCH
When stopping mid-phase because of a blocker, pause, or harness switch:
- Finish or safely stop the current atomic file operation.
- Do not begin another execution step.
- Record partial work accurately.
- Record commands run and verification state.
- Record uncommitted files.
- Record the exact blocker.
- Set the next action.
- Print the complete updated HANDOFF.md.
- Print the Resume Block.
- Stop.
Do not mark a partially completed step DONE.
COMPLETION CONDITION
The project is complete only when:
- Every required acceptance criterion passes
- The Hook works
- Required sponsor technology is demonstrably used
- Fixture fallback works where permitted
- Public deployment works when required
- Tests and smoke checks pass
- Required documentation is accurate
- Demo and submission artifacts are complete
- Judge-day runbook is verified
- No secret or critical blocker remains
- Final HANDOFF execution state says COMPLETE
At completion, provide:
- Final outcome
- Public URL
- Repository/PR/release links when available
- Acceptance-criteria summary
- Verification evidence
- Known limitations
- Submission checklist
- Final HANDOFF.md
Do not add celebratory filler or propose new features.
START HERE
If HANDOFF.md is missing:
- Ask only for the complete Prompt 1 HANDOFF.md
- Stop
If HANDOFF.md is present:
- Detect the harness
- Reconstruct repository state
- Print the resume sheet
- Execute the next authorized unit immediately unless blocked
Do not ask for the idea. Do not redesign the plan. Do not begin an unauthorized step. Do not claim success without verification.
CHECK: questions_this_turn=1 step=none autonomy=A1 packet=none stage=C
I'll start from the locked handoff and the current repository, then execute the next authorized step.
Repository evidence matches the locked plan. P0.1 is an access check, so I am recording the matrix and the safe ignore rules without creating the user-owned branch.
Resume
- Project: Happen
- Product thesis: Happen helps a friend choose the best-supported restaurant and arrival window for the experience they want.
- Locked Hook: Three restaurant timelines resolve across the evening until one interval illuminates as the recommended moment, with fit, confidence, evidence, and a fallback.
- Harness: agent
- Autonomy: A1
- Repository and branch:
https://github.com/kernelKain/happenonmainata45880a.build/happen-mvpdoes not exist. - Working-tree state: Untracked
.gitignoreanddocs/BUILD_LOG.md.docs/HANDOFF.mdis ignored and preserved. - Last completed step: P0.1
- Next step: P0.2 — Prove SerpApi evidence shape
- Current phase: P0 — prove access and feasibility
- Deadline: October 5, 2026 at 06:59 UTC / 12:29 PM IST
- Feature-freeze status: Not reached (build hour 19 of 24)
- Remaining known budget: 24 planned active hours. This step was not timed, so consumed time is unknown.
- Live URL: Not deployed
- Fixture status: No fixture yet
- Largest current risk: Live SerpApi, Gemma, and Render proofs cannot run until credentials and the Render balance are available locally.
- Quality items already dropped: None
- HANDOFF/repository discrepancy: None. Git matches the locked baseline.
STEP P0.1 — Verify accounts and workflow controls Phase: P0 — prove access and feasibility Autonomy: A1 Status: COMPLETE
Goal: Record toolchain versions, account and workflow status, and blockers without printing secrets or changing Git history.
Changes:
.gitignore: Ignores secrets, local environments, model binaries, provider payloads,.entire/settings.local.json, anddocs/HANDOFF.md.docs/BUILD_LOG.md: Records the P0.1 access matrix and the evidence behind each status.docs/HANDOFF.md: Execution state now marks P0.1 complete and P0.2 next.
Verification:
- Git: public
mainata45880a, trackingorigin/main. No execution branch and no pull requests. - Toolchain: Python 3.14.4 on PATH, locked 3.13 available from
uvas 3.13.15, Node 22.14.0, npm 10.9.2, uv 0.12.5, Entire CLI 0.11.3, GitHub CLI authenticated askernelKain. - GitHub Actions: enabled, with default workflow permission
read. - Entire:
entire statusreports not set up..entire/was not created. - DevRelay: MLH is connected and DEV user
kernelkainresolves. No session was published. - CodeRabbit: no config file, which matches the locked default. The current GitHub token cannot list App installations.
- Credentials:
SERPAPI_API_KEYandHF_TOKENare unset. Render CLI is absent, so the credit balance was not read. - Acceptance criteria: AC-17 and AC-20 are only evidenced for this access check. They are not complete.
Decisions:
- Python 3.13.15 will be installed with
uvat P1.1. The system interpreter remains 3.14.4. - CodeRabbit and Entire setup are time-boxed. They do not block the runtime proofs.
- The active harness is Cursor. Entire should be enabled for the agent that actually does the work.
Risks or limitations:
- P0.2 cannot send a live request until
SERPAPI_API_KEYis set in a local ignored environment file. Do not paste the key into chat. - P0.3 still needs a local
HF_TOKENafter Gemma terms are accepted, plus the Render credit balance and plan price from the Render dashboard. - Create
build/happen-mvpfrommainbefore implementation. Under A1 this agent will not create the branch.
HANDOFF update:
- Completed: P0.1
- Next: P0.2
- Clock/freeze status: Feature freeze not reached. Spend remains $0. Measured active time is unknown.
Configure SERPAPI_API_KEY locally, then reply ok to start P0.2.
CHECK: questions_this_turn=1 step=P0.1 autonomy=A1 packet=none stage=C
revert back chnages in handoff file, then create new HANDOFF2.md in Docs and update all the work and notes of impleention from phase 0 to final phase in that.;;; ALso keep HANDOFF2.md easy to read for human, they act as both notes for me and for Cursor to understand what has been done till now. Update each step of each phase notes in it.;;; Also for each phase create a separte branch and for each step of each phase do a separte commit message(1 line);; Also tell me what i need to do in that step if needed.;; Then after doing all this move to next step.;; DO not put HANDOFF files in .gitignore, i want it to be visible to public so they can understand my process;;; Tell me things i need to do from my side in each step after you side impleemntation.
The locked plan stays in HANDOFF.md. I’ll restore that file, put the execution notes in a public HANDOFF2.md, and record P0.1 on its own phase branch before starting P0.2.
The locked plan in HANDOFF.md will go back to its original text. Progress notes will live in a public HANDOFF2.md, and P0.1 will be committed on a phase branch.
docs/HANDOFF.md is back to the locked plan. Progress now lives in public docs/HANDOFF2.md, and P0.1 is committed on phase/p0-prove-access as 43962ef. P0.2 is blocked until you set the SerpApi key locally.
The locked plan was not rewritten. These notes are the public record of what has been done and what is still yours:
docs/HANDOFF.mdis the original specification again.docs/HANDOFF2.mdhas every phase and every step, with Cursor’s work and your side written in plain language.- Neither file is ignored. Both are in the commit.
- This phase uses
phase/p0-prove-access. Later phases get their own branch at the first step of that phase, so those branches are not empty copies of today’s commit. - Commit:
P0.1: record account and workflow access checks. - The branch is local only. It has not been pushed.
P0.2 — Prove SerpApi evidence shape
Status: BLOCKED
The workspace has no .env file, and SERPAPI_API_KEY is not set. No search was sent, so no credits were used.
Set the key in /home/kernel-kain/Documents/Github/happen/.env:
Put the real key in that file on your machine. Do not paste it here. Reply ok after it is saved.
After the probe finishes, read the balance and search count in HANDOFF2.md. If the account has fewer than the planned 250 searches, say so before any larger live run.
Your side for the later steps is already written in docs/HANDOFF2.md. The parts that cannot be done from this repo are:
- P0.3: Accept the Gemma terms if Hugging Face requires it, set
HF_TOKENwhen the model is gated, and read your Render credit balance and plan price from the Render dashboard. - P1.4: Push the branch, create the Render services, store the key there, and send back the public URLs.
- P2.6: Open the local page once and confirm the three timelines, the highlighted moment, and the fallback.
- P3.4: Approve the one live capture before credits are spent, then skim the sanitized fixture.
- P3.5: Start a free Colab T4 session if you want tuning checked.
- P3.6 and P6: Deploy the exact revision and open the public page.
- P4.4: Run the five-minute friend walkthrough and send a paraphrase with no name or contact details.
- P5.4: Review and merge. That merge is feature freeze.
- P7–P8: Approve sessions and media, keep the DEV article as a draft until you publish it, then submit the challenge yourself.

added servapi key to .env file;; also in commi mesgage do not use terms like P0.1, P0.2, just the messgage not the stpe and phase to be iclcude in commit mesgage;; what else i need to do right now;;
The SerpApi key is in place, so I’ll run the bounded Indiranagar probe next and keep the key out of the notes and the commit message.
The key is present and will stay out of the logs. I’m checking the account balance, then one small Indiranagar search, place details, and reviews.
The SerpApi key works. You do not need to do anything else for that account right now.
The Indiranagar search returned 20 restaurants. Chianti and Truffles have both weekly hours and popular-times graphs, so two places already have comparable time evidence. Bombay Brasserie has hours but no popular times, which stays an unknown rather than a good sign. The reviews call returned five dated, linked excerpts. The free plan still has 245 of 250 searches left, so the planned budget still fits.
The notes are in docs/HANDOFF2.md. The commit on phase/p0-prove-access is f50c038, with the message Record the Indiranagar restaurant evidence probe. The .env file was not committed.
Before the Gemma and Render proof, only you can do these two things:
- On Hugging Face, open
google/gemma-3-270m-itand accept the model terms if the page asks. If a token is required, addHF_TOKENto the same ignored.envfile. Do not paste the token here. Reply that it is set, or that the model page did not ask for one. - In the Render dashboard, read your credit balance and the price of the
2c-4gplan. Send those two numbers only.
Entire, CodeRabbit, pushing the branch, and Colab can wait. They are not needed for the next proof.

the gemma acceopte model terms, but don't know when to geanrte toke if need, also make sure its free for building this project and oepartiong it, i don't want to pyay, model page did not ask anything else like token ;;; redner $50.00 credits remain;;
Gemma terms are accepted and Render still has $50 in credits. I’ll check that local Gemma stays free to run, then measure whether those credits cover the Render plan without any new payment.
The public quantized model downloaded without a token. Next I’ll load it locally and measure memory, since the free Render instance is too small to run it.
The model runs locally with no token and no per-request fee. I’m recording the memory, the checksum, and how the $50 Render credits have to be used so a card is never charged.
You do not need to generate a Hugging Face token. Gemma is free to build and run for this project, and the $50 Render credits can cover the public site through the deadline without a new payment.
Accepting the model terms was the step the site asked for. A token is a separate password a script would use to download the official weights. The demo does not need that download. A public quantized copy of the same Gemma 3 270M model downloaded with no token, loaded locally, and answered in about 2.5 seconds using 372 MB of memory. Nothing was sent to a paid model API.
Create a token only later, and only if a Colab download of the official google/gemma-3-270m-it weights says access is restricted. The token itself is free. Do not turn on a Hugging Face inference endpoint, and do not buy Colab time. Tuning can wait, and it stays on a free Colab session if it happens at all.
Render is the one place money can leak, and only if a service is left on:
- The static site is $0.
- The free web service has 512 MB of RAM. The model alone used 372 MB, so the API will not fit there.
- A 1 CPU / 2 GB backend is listed at $25 per month. The larger 2 CPU / 4 GB plan is $85 per month. Render takes that from the $50 credits only while the service is running.
- Those credits last about 60 days on the smaller plan, or about 18 days on the larger one, if it stays on all day. Through tomorrow’s deadline, either plan is a few dollars of credits.
Nothing else is required from you before the app scaffold. Before the first Render service is created, set the workspace spend limit so usage cannot charge a card after the credits run out, and do not add a payment method if Render lets you skip it. After judging, suspend the paid web service. The static site can stay.
The notes are in docs/HANDOFF2.md. The commit is ee36c6e on phase/p0-prove-access: Record the free Gemma runtime proof and Render credit limit.

P0 is done, so the next step is the monorepo scaffold. I’ll put it on the P1 branch and keep the installs inside the locked versions.
The monorepo scaffold is in place on phase/p1-walking-skeleton. You do not need to do anything for this step.
The backend installs on Python 3.13.15, and happen_api imports cleanly with the locked packages, including the local Gemma runtime. The frontend production build succeeds with React 19 and Vite 8. The page is only the name and the tagline so far. The planner screen is the later UI step.
React 19.3.0 does not include TypeScript declarations, so @types/react 19.3.0 and @types/react-dom 19.3.0 were added. Both are MIT. No locked runtime version changed.
The pinned model checksum is in ml/model-manifest.json. The model file itself stays out of git. Secrets stay in the ignored .env; .env.example has empty values only.
Commit 16acedc: Scaffold the backend, frontend, and model manifest.
CHECK: questions_this_turn=0 step=P1.1 autonomy=A1 packet=none stage=C
Briefly inform the user about the task result and perform any follow-up actions (if needed). If there's no follow-ups needed, don't explicitly say that.
The backend dependency install finished successfully and is already part of the scaffold commit 16acedc on phase/p1-walking-skeleton. Python 3.13.15 resolved the locked packages, including llama-cpp-python 0.3.36.
I'll push phase/p1-walking-skeleton and open a draft pull request against main, without making any new commits.
Draft pull request opened against main: https://github.com/kernelKain/happen/pull/1
do not use p1, p2 etc not in commenets and not in branch anms, not in commit messgage rekpp phase numbering and step numbering iut of there, for all.
Phase and step numbers should stay out of branch names, commit messages, and comments. I’ll find those labels and rename the current branch so the pull request matches.
The published branch and one commit still carry those numbers. I’ll move the work onto walking-skeleton and take the numbers out of the notes and that commit message.
The new branch has plain commit messages. Next I’ll take the phase and step numbers out of the notes, then point the draft pull request at walking-skeleton.
Phase and step numbers are out of the branch name, the commit messages, and the running notes.
The current branch is walking-skeleton. Its commits are plain sentences, starting with Record account and workflow access checks. The draft pull request is https://github.com/kernelKain/happen/pull/2. The earlier numbered branch and its draft pull request are closed.
Later branches will use the same pattern: fixture-hook, live-sponsor, demo-experience, and so on, with no p1 or p2 in the name. Code comments follow the same rule. The locked plan in docs/HANDOFF.md still uses those labels because it is the original specification.

do not include curosr name , ect in commit emsgage for eachstep, just what it does and prorpelry written short commit mesgage for each step and phase; after creating PR for each branch i will od code review by code reabbit, which then will make chaegs so before starting eevry next phase pull the laetst changes from remote repo to local repo so there are no merge conflict.;; also check when entire will e set up and how to set it up
Commit messages should only say what changed. I’ll check the current history, record the CodeRabbit pull rule, and look up how Entire is actually set up.
Entire is installed and you are logged in, but this repository is not enabled yet. I’ll record the short commit style and the rule to pull CodeRabbit’s changes before the next phase.
Commit messages stay one short sentence about the change itself. They will not name the coding tool, and they will not use phase or step numbers. The local walking-skeleton branch matches the remote, including that rule.
After you open a pull request, run the CodeRabbit review and let it push its changes. Before the next phase starts, those remote changes get pulled first so the new branch begins from the updated tip.
Entire is not set up in this repository yet. The CLI is installed, and the GitHub login is already active, so this is the moment to enable it: before the next phase, so later commits get checkpoints. The commits already on walking-skeleton will not gain checkpoints retroactively.
In the repository, run:
That writes .entire/settings.json, which should be committed, and leaves .entire/settings.local.json untracked. Checkpoints publish when you push. If entire status still says it is not set up, stop there and send the status text. Do not paste any token.
The draft pull request is still https://github.com/kernelKain/happen/pull/2.

also before starting next phase i want to tets the app manuallya nd see changes myself, so tell me how to do it for both frneoten dan abckedend, ect for entire: Install the CLI Install Entire in your terminal.
curl -fsSL https://entire.io/install.sh | bash 2 Log in Link the CLI to your Entire account.
entire login 3 Enable checkpoints From any Git repository, enable Entire so every push can publish checkpoints.
entire enable 4 Code and push Work with your coding agents as usual. When you push, Entire links captured sessions to your commits and your first checkpoint will appear here.;;;; also i will do every next phase work in new chat so tell me when current phase is totaly cmplete and udpated handoff2 fiel and build log, etc so that i will just feed prompt2 in new chat and it will know where we are and what to do next,, also update al the addiitonal isntruction i gave you in reequried docs so that it follow them in new hcat for new phase.
The walking-skeleton phase is not finished yet. I’ll write the local run steps and your review rules into the notes so a new chat can resume at the right step.
The walking-skeleton phase is not complete, so this is not the moment to open the next phase. docs/HANDOFF2.md and docs/BUILD_LOG.md are updated and pushed on walking-skeleton. A new chat that receives Prompt 2 should continue with the health and metadata API, not with the fixture work.
What you can check by hand today:
Frontend:
Open the address Vite prints, usually http://127.0.0.1:5173. You should see “Happen” and “Know where. Know when.” Stop the server with Ctrl+C.
Backend:
That prints 0.1.0. There is no API server to open in a browser yet. That arrives with the health step.
Entire is already installed, and you are already logged in. From the repository root, the remaining step is:
After that, work as usual. The first checkpoint shows up when you push. If you ever set this up on a machine without the CLI, the full sequence is curl -fsSL https://entire.io/install.sh | bash, then entire login, then entire enable.
This phase is finished only after the health API, the frontend shell, and the first public deployment are done, you have looked at them, and the CodeRabbit review on https://github.com/kernelKain/happen/pull/2 has been pulled. Then the next chat can start the following phase.
CHECK: questions_this_turn=0 step=none autonomy=A1 packet=none stage=C
The notes are already pushed. I’ll check the new untracked files and commit only the ones that belong on this branch.
Entire’s local config is the only uncommitted work. I’ll commit those checkpoint files and leave logs, metadata, and secrets out.
Pushed 9e444e3 to walking-skeleton: Enable repository checkpoints for agent sessions.
That commit adds the Entire settings and agent hooks (.entire/settings.json, .entire/.gitignore, and the Cursor, Codex, and agents hook files). Logs, metadata, and local secrets stayed out of the commit. The branch matches origin/walking-skeleton, so draft pull request https://github.com/kernelKain/happen/pull/2 now includes it.
