name: builder-checklist description: Builder implementation checklist used to drive todowrite and execution order.

Purpose

Use this checklist to create and maintain a todowrite TODO list and to execute Builder work in a predictable, traceable order.

Required behavior

• Immediately create a TODO list with todowrite that mirrors the checklist items.
• Keep the TODO list updated as you work (mark items in_progress / completed / cancelled).
• Keep exactly one item in_progress at a time.
• The TODO list is for determinism/traceability only; it does NOT replace required on-disk artifacts.

Implementation checklist (follow in order when possible)

• (MANDATORY) Initialize the todo list with todowrite (mirror this checklist)
• (MANDATORY) Read AGENTS.md and, if present, REVIEW_RULEBOOK.md to refresh requirements and constraints
• (MANDATORY) Read the assigned task and restate it briefly
• (MANDATORY) Identify the files and modules likely involved in the change
• (MANDATORY) Implement the required changes with minimal, focused diffs
• (MANDATORY) Update or add tests for any new or changed behavior (Vitest/Playwright as appropriate)
• (MANDATORY) Run pnpm install (components/) if dependencies are missing
  • If pnpm install cannot run (for example due to network restrictions), treat it as a hard failure:
    • write builder_result.json with run.status = "failed", run.failed_step = "pnpm install", run.error set to the exact error output, and work = null
    • then proceed to the builder-signoff skill so Foreman can stop safely.
• (MANDATORY) Run pnpm lint (components/) and record pass/fail
  • If it fails due to formatting (Prettier), you MAY run pnpm format (components/) and then re-run pnpm lint.
  • If lint still fails, still proceed; record the failure in your handoff.
• (MANDATORY) Run pnpm check (components/) and record pass/fail
  • If it fails, still proceed; record the failure in your handoff.
• (MANDATORY) Run pnpm test:unit (or broader pnpm test when appropriate) (components/) and record pass/fail
  • If it fails, still proceed; record the failure in your handoff.
• (OPTIONAL) Run pnpm prepack (components/) when packaging changes are involved and record pass/fail
  • If you are unsure whether packaging is involved, run it.
• (MANDATORY) Prepare the Git state: stage all relevant files with git add so that git diff main...HEAD reflects the full change
• (MANDATORY) Create a local commit with a clear, concise message
  • If git commit fails for any reason, treat it as a hard failure (Foreman depends on the commit for git diff HEAD...main):
    • write builder_result.json with run.status = "failed", run.failed_step = "git commit", run.error set to the exact error output, and work = null
    • then proceed to the builder-signoff skill so Foreman can stop safely.
• (CRITICAL) (MANDATORY) Execute the builder-signoff skill (writes builder_result.json + validates + prints Public Handoff)

Result JSON requirement (always)

No matter what happens ALWAYS write builder_result.json and validate it with validate_builder_result (in-process tool).

• If the validator reports issues: fix the JSON and re-run until it passes.
• If the validator tool itself cannot be executed (tool missing/unavailable): treat it as a hard failure and write builder_result.json with run.status = "failed", run.failed_step = "validate_builder_result", run.error set to the exact error output, and work = null, then proceed to the builder-signoff skill so Foreman can stop safely.
