What problem does it solve? Reviewing Python patches by hand often misses subtle defects in exception propagation, resource cleanup, concurrency, and security boundaries. This Skill provides a structured, read-only review workflow that produces severity-ordered, evidence-grounded findings instead of vague style opinions. ## Core Features & Use Cases - Security Review: Traces interpolated SQL, subprocess arguments, file path containment, and exposed secrets through the changed code. - Correctness Review: Checks exception handling, resource lifetimes, type contracts, shared mutable state, and async/concurrency hazards. - Framework Checks: Covers Django, FastAPI, and Flask specifics such as transaction invariants, Pydantic model separation, and CSRF handling. - Use Case: A teammate submits a pull request touching database access and async handlers. Ask for a review and receive findings with file/line, trigger, consequence, and fix direction, plus a list of evidence gaps. ## Quick Start Review this Python patch for security, typing, exception handling, and concurrency defects and report severity-ordered findings.
