+description: Use when creating implementation plans that need quality review before execution — 4-phase workflow combining plan creation with automated plan-reviewer validation
+---
+
+# Plan and Review
+
+## Overview
+
+Create implementation plans and validate them through automated review before execution. This skill combines the writing-plans methodology with plan-reviewer agent dispatch to catch quality issues (missing file paths, vague acceptance criteria, scope gaps, TDD omissions) before any code is written.
+
+**Announce at start:** "I'm using the plan-and-review skill to create and validate the implementation plan."
+
+**Core principle:** No plan reaches execution without passing review. Critical/High findings must be resolved first.
+
+## The 4 Phases
+
+```
+Phase 1: Create Plan → Phase 2: Review → Phase 3: Revise (if needed) → Phase 4: Approved
+```
+
+### Phase 1: Create Plan
+
+Use the writing-plans methodology to create the implementation plan.
+
+1. **Invoke the writing-plans skill** (superpowers:writing-plans or equivalent)
+2. Follow all writing-plans requirements:
+   - Bite-sized tasks (2-5 minutes each)
+   - Exact file paths for all changes
+   - TDD structure (Red-Green-Refactor) for core logic
+   - Complete code in plan (no placeholders)
+   - Alternatives exploration for non-trivial decisions
+3. Save plan to `docs/plans/YYYY-MM-DD-<feature-name>.md`
+
+### Phase 2: Dispatch Plan Reviewer
+
+Dispatch the plan-reviewer agent as a subAgent to review the plan.
+
+1. **Dispatch plan-reviewer** using the Agent tool:
+   ```
+   subagent_type: "general-purpose"
+   prompt: |
+     You are the Plan Reviewer agent. Review the implementation plan at
+     docs/plans/<plan-file>.md against the original spec/issue.
+
+     Review checklist:
+     - File paths: All paths valid (Modify files exist, Create paths have valid parents)
+     - Acceptance criteria: Specific, measurable, verifiable (no vague terms)
+     - Scope alignment: Plan matches spec — no scope creep, no missing items
+     - TDD compliance: Red-Green-Refactor for core logic tasks
+     - Backward compatibility: Breaking changes documented with migration steps
+
+     Output a severity-rated findings table:
+     | Finding | Location | Severity | Recommendation |
+
+     End with Review Summary showing counts per severity and verdict:
+     APPROVED (Critical=0 AND High=0) or REVISE REQUIRED.
+   ```
+2. Collect the review results
+
+### Phase 3: Revise Plan (if Critical/High findings)
+
+If the review verdict is **REVISE REQUIRED**:
+
+1. Read each Critical and High finding
+2. Revise the plan to address each finding:
+   - Fix invalid file paths
+   - Make acceptance criteria specific and testable
+   - Add missing spec requirements as tasks
+   - Add TDD structure where missing
+   - Document breaking changes with migration steps
+3. Save the revised plan (overwrite the same file)
+4. **Re-dispatch plan-reviewer** (return to Phase 2)
+5. Repeat until verdict is **APPROVED**
+
+**Maximum iterations:** 3 revision cycles. If still not approved after 3 cycles, present remaining findings to user for manual resolution.
+
+### Phase 4: Plan Approved
+
+When the review verdict is **APPROVED**:
+
+1. Announce: "Plan approved by plan-reviewer — ready for execution."
+2. Present remaining Medium/Low findings as optional improvements
+3. Offer execution choice:
+   - **Subagent-Driven (this session):** Use superpowers:subagent-driven-development
+   - **Parallel Session (separate):** Use superpowers:executing-plans
+
+## When to Use This Skill
+
+- Creating implementation plans for non-trivial features
+- Plans that will be executed by other agents or in separate sessions
+- When plan quality is critical (e.g., parallel execution with multiple workers)
+- When the spec is complex and scope alignment matters
+
+## When NOT to Use This Skill
+
+- Single-file changes or trivial fixes
+- Plans you will execute yourself immediately in the same session
+- Exploratory prototyping where the plan will evolve rapidly
+
+## Integration with Parallel Orchestrator
+
+When used within parallel execution workflows:
+
+- The conductor generates worker directives that include plan creation
+- Each worker can use this skill to self-validate their plan before ACT mode
+- The plan-reviewer findings feed into the conductor's quality gates
+
+## Key Principles
+
+- **No plan without review** — every plan gets at least one review pass
+- **Severity drives action** — Critical/High must be fixed, Medium/Low are optional
+- **Evidence-based findings** — every finding references a specific plan section
+- **Bounded iteration** — maximum 3 revision cycles to prevent infinite loops
+- **Clear verdict** — APPROVED or REVISE REQUIRED, no ambiguity
