vcsdd-impl

name	vcsdd-impl
description	Run Phase 2b (implementation, Green phase) and Phase 2c (refactor) for the active VCSDD feature. Invokes vcsdd-builder to implement minimal code to pass failing tests, then refactor.

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
