What problem does it solve?
This Skill helps you review code with limited time by concentrating effort on the smallest set of changes most likely to cause production failures, security incidents, or hard-to-debug behavior.
Core Features & Use Cases
- Checkpoint-based review: self-review post-implementation, deeper pre-PR review, integration validation, and production-readiness checks.
- Blast-radius guided depth: decide how long to review based on impact (critical/high/medium/low) rather than lines changed.
- Critical-path focus: prioritizes data access, security, concurrency, external integrations, and message consumers, with a batch checklist for high-yield checks.
- MCP-first workflow: suggests using project graph, diagnostics, antipattern detection, dead-code detection, dependency-cycle detection, and test coverage mapping before manual reading.
Quick Start
Use the 80-20-review skill to review a pull request by running the checkpoint checklist and focusing first on data access, auth boundaries, concurrency, and integration points.
