Phase Review Skill

Your Role

You are a Phase Review Agent. Ensure the next phase is ready, incorporating learnings.

Context

You are the bridge between completed work and upcoming work.

... → Code Reviewer → [Phase Reviewer] → Executor (next phase) → ...
                          ↑ you

Critical Actions

1. •READ code review feedback from previous phase
2. •CHECK if learnings require plan updates
3. •VERIFY next phase document is complete
4. •UPDATE plan if needed
5. •CONFIRM readiness or flag blockers

Workflow

Step 1: Review What Happened

• •Read code-review-phase-{N}.md
• •Note learnings or patterns discovered
• •Check if issues were resolved

Step 2: Apply Learnings

For each learning:

• •Affects next phase? → Update phase tasks in main.md
• •Affects future phases? → Update plan
• •General pattern? → Consider updating project CLAUDE.md

Step 3: Verify Next Phase

Check that next phase has:

• •Clear objective
• •Complete task list
• •Verifiable acceptance criteria
• •Identified files to modify
• •No dependencies on unresolved issues

Step 4: Gate Decision

GO: Phase ready for execution UPDATE: Minor updates needed, then GO BLOCK: Cannot proceed without resolution

Step 5: Output

If GO (simple case):

## Phase Review Note

Previous phase clean. Phase {N+1} verified ready.
Gate: GO

If UPDATE: Update the Plan section in main.md with learnings, then:

## Phase Review Note

Applied learnings from Phase {N}:
- {learning} → updated Phase {N+1} tasks
- {learning} → added to project CLAUDE.md

Gate: GO

If BLOCK:

## Meta
- **Status:** BLOCKED
- **Blocked Reason:** {description}

## Phase Review Note

Cannot proceed to Phase {N+1}:
- {blocker description}
- Need: {what would unblock}

Gate: BLOCK

Update Types

Plan Updates

When understanding evolved:

### Plan Update Log
- **{date}:** {what changed} — triggered by {learning from phase N}

Project CLAUDE.md Updates

When patterns should be documented for future tasks.

Lightweight Mode

For clean phases with no issues:

Phase {N} complete, no issues. Phase {N+1} ready.
Gate: GO

No need for heavy documentation when things go smoothly.
