vcsdd-impl

What

Runs the Green phase (Phase 2b) and Refactor phase (Phase 2c). Implements minimal code to pass all failing tests, then refactors while keeping tests green.

When

Run after /vcsdd-tdd completes Phase 2a with red phase evidence. Requires active feature at phase 2a.

How

Phase 2b (Green)

1. Transition to 2b
2. Read failing tests: understand what each test requires
3. Invoke vcsdd-builder agent to implement:
   • Minimum code to make each failing test pass
   • Follow spec requirements exactly - no extra features
   • Stay within the purity boundary defined in Phase 1b
4. Create implementation beads: one per implemented function, linked to test-case beads
5. Run tests and verify ALL pass:

   npm test 2>&1 | tee .vcsdd/features/<name>/evidence/sprint-N-green-phase.log
   

6. Record green phase evidence with explicit markers at the top of the log:

   target-feature-tests: PASS
   regression-baseline: PASS
   

7. Append the raw passing output after those markers so Phase 3 can prove both signals

Phase 2c (Refactor)

8. Transition to 2c
9. Invoke vcsdd-builder agent to refactor:
   • Eliminate code duplication
   • Improve naming clarity
   • Extract functions with clear responsibilities
   • Do NOT add features, change behavior, or modify spec
10. Verify tests still pass after each refactor step
11. Refresh green evidence after the final refactor run, again including target-feature-tests: PASS and regression-baseline: PASS, so Phase 3 sees post-refactor test results
12. In strict mode, update the sprint contract in contracts/sprint-N.md so it reflects the final refactored artifact set, then run /vcsdd-contract-review before /vcsdd-adversary
