Execute

Implements phases from an existing BLUEPRINT.md using a strict test-driven development loop.

Core Workflow

1. Find task -- Read BLUEPRINT.md, locate the first unchecked [ ] task
2. Read contract -- Check the Contracts section for exact signatures and behavior
3. TDD loop -- Write test -> run (must fail) -> implement -> run (must pass)
4. Mark done -- Check [x] in BLUEPRINT.md
5. Commit -- git add .; git commit -m "feat(phase-N): task X.Y"
6. Repeat -- Move to next task

Phase Completion

Run the phase gate condition from BLUEPRINT.md. If it passes:

• Update .agents/CONTEXT.md with completed phase
• Create worktree for next phase if needed

If gate fails after 2 attempts:

• Write to .agents/failures.md
• Create handoff via the handoff skill
• Move on to unblocked work

Constraints

MUST DO

• Implement exactly what the contract specifies
• Run tests before and after every change
• Mark tasks done only after tests pass
• Commit after each completed task
• Update .agents/CONTEXT.md at session end

MUST NOT DO

• Improvise wrong signatures, return types, or error behavior
• Skip the TDD red-green cycle
• Move to the next phase with failing tests
• Make architectural decisions not in the blueprint

Session End Template

Update .agents/CONTEXT.md with:

Stopped at: Phase N, Task N.X
Completed: [list]
Blockers: [list or none]
