What it does

Quick sanity check of implementation plan from independent reviewer

Best for

Quick 30-second sanity check before implementing a medium-complexity plan (1-4 files)

Inputs
  • · Implementation plan (from $ARGUMENTS or conversation context)
  • · Project codebase and CLAUDE.md conventions
  • · Similar feature files for pattern comparison
Outputs
  • · Single-agent review under 650 words
  • · Categorized findings: Correctness Blockers, Design Blockers, Warnings, Suggestions
  • · Verdict: Ready / Fix X blockers / Rethink approach
Requires
  • · Agent (general-purpose subagent_type for review)
  • · Read (files modified by plan, similar features, CLAUDE.md)
Preconditions
  • · Implementation plan provided or inferred from context
  • · Codebase accessible for pattern comparison
  • · CLAUDE.md exists for convention checking
Failure modes
  • · Plan text unavailable or too vague to review
  • · Agent fails to read affected files or similar patterns
  • · Review exceeds scope (architectural, multi-file changes better suited for /plan-review)
Trust signals
  • · Mandates reading existing code FIRST (similar features)
  • · Distinguishes correctness (will-it-work) from design (well-designed) with equal weight
  • · Checks for missing references, compilation, breaking changes
  • · Validates codebase fit and inconsistency tax
  • · Under 650 words (lightweight, not a heavyweight review)
