version: "1.0.1" description: Review implementation plans for completeness and feasibility. Use when user says "review this plan before I start", "is this implementation plan complete", "check if this plan aligns with our patterns", "give me feedback on my implementation strategy", or "validate this plan before we execute it". allowed-tools: Read, Glob, Grep, LS, WebSearch, WebFetch, Task(subagent_type:plan-reviewer-agent) model: opus

Plan Reviewer

Critically analyze implementation plans for quality, completeness, and feasibility.

When to Activate

• User has a plan file to review
• Validation needed before execution
• Feedback requested on implementation strategy
• User asks "does this plan look good?"
• Before executing a planned implementation

Workflow Integration

This is Step 3 of the implementation workflow:

1. Explore → 2. Plan → 3. Review (this) → 4. Execute

Quick Process

1. Load Plan: Read the plan file
2. Analyze: Check completeness and conciseness
3. Validate Scope: Ensure no extras beyond requirements
4. Identify Risks: Report the implementation risks you find, each with a severity
5. Check Alignment: Verify against codebase patterns
6. Provide Feedback: Actionable improvement suggestions

Output Format

Returns structured review:

• Summary: Plan quality and main assessment
• Strengths: What the plan does well
• Concerns: Issues with severity and suggestions
• Gaps: Missing critical elements
• Improvements: Enhancement recommendations
• Feasibility: Complexity and risks with severity
• Alignment: Pattern compliance check
• Scope Validation: Requirements adherence

Review Focus Areas

• security: Security considerations and vulnerabilities
• performance: Performance implications and optimizations
• default: All aspects

Context Integration

Automatically uses context from a prior explore-codebase run when available:

• Key components and responsibilities
• Existing patterns and conventions
• Dependencies and integration points
• Known gotchas and edge cases

Delegation

Invokes plan-reviewer-agent with plan file and context.
