Matrix Code Review

Perform a comprehensive, context-aware code review using Matrix's review pipeline with full index integration.

Tip: This skill runs in a forked context for an unbiased perspective - similar to how a human reviewer would approach the code for the first time.

Usage

Parse user arguments from the skill invocation (text after the trigger phrase).

Expected format: <target> [mode]

• target: File path, PR number, or "staged" for staged changes
• mode (optional): default | lazy (default: from config or default)

Modes

Default Mode (Comprehensive)

Full 5-phase review pipeline with maximum index utilization:

• Blast radius analysis via matrix_find_callers
• Symbol lookup via matrix_find_definition and matrix_search_symbols
• Memory recall via matrix_recall for relevant past solutions
• Deep security and edge case analysis
• ~10+ comments, thorough coverage

Lazy Mode (Quick)

Single-pass review for fast feedback:

• Direct code inspection only
• No index queries (faster)
• Main issues only
• ~2-3 comments

Review Pipeline

Follow the 5-phase review pipeline detailed in references/review-phases.md:

1. Phase 1: Context Mapping - Calculate blast radius, find callers, build dependency graph
2. Phase 2: Intent Inference - Classify change type, summarize purpose
3. Phase 3: Socratic Questioning - Generate probing questions about edge cases, errors, security
4. Phase 4: Targeted Investigation - Check patterns, verify assumptions, research
5. Phase 5: Reflection & Consolidation - Generate final review with confidence score

Examples

/matrix:review src/utils/auth.ts          # Default mode (comprehensive)
/matrix:review staged                     # Review staged changes
/matrix:review staged lazy                # Quick review of staged changes
/matrix:review 123                        # Review PR #123
/matrix:review 123 lazy                   # Quick review of PR #123
