description: "Implement features in committed phases with rollback safety. Use for any multi-file or multi-phase implementation. Auto-invoke when the user says 'implement the plan', 'build this feature', 'multi-phase', or references an implementation plan."

Phase-Based Checkpoint Implementation

Workflow

For each phase in the implementation plan:

1. Implement

Complete all work for this phase only. Do not touch files belonging to future phases.

2. Verify

Run npm run build (or the project's build command). If the build fails:

  • •Fix the issue within this phase's scope
  • •Run the build again
  • •If you cannot fix it without modifying earlier phases, STOP and tell the user

3. Commit

Once the build passes, commit with a descriptive message: git add -A && git commit -m "feat(<feature>): phase N - <description>"

Example messages:

  • •feat(focus-queue): phase 1 - database migration and RLS policies
  • •feat(focus-queue): phase 2 - backfill existing emails into queue
  • •feat(focus-queue): phase 3 - React Query hooks for CRUD
  • •feat(focus-queue): phase 4 - UI components and page layout

4. Proceed

Only after the commit succeeds, move to the next phase.

Critical Rules

  • •NEVER start phase N+1 until phase N is committed
  • •NEVER modify files from a previous phase without explicit user approval
  • •If a later phase reveals issues in an earlier phase, tell the user before making changes
  • •Each commit should represent a working (buildable) state
