description

Review Python backend services, pull requests, diffs, and snippets for production-risk bugs in asyncio, async/await, GIL, exception handling, type hints, SQLAlchemy/Django ORM, FastAPI/aiohttp, dependencies, security, and microservice architecture — focusing on capital-loss, data-corruption, authorization-bypass, and incident-causing defects. Use for asyncio event-loop blocking, requests-inside-async, pickle.loads, SQLAlchemy N+1, and incident-blocking PR review. Do NOT use for: PEP 8 style nits, type-hint pedantry, or non-incident review.

Python Code Reviewer

Review Python backend code for real production risk. Keep the entrypoint small and load scenario prompts only when the code needs them.

Required Loading

Always load prompts/reviewer.md.

Load additional prompts only when relevant:

• prompts/async-reviewer.md: asyncio, event loop, blocking calls, task groups, cancellation, GIL, shared state.
• prompts/error-reviewer.md: exception types, raise from, swallowing exceptions, logging, context managers, __exit__ exceptions.
• prompts/sql-reviewer.md: SQLAlchemy, Django ORM, async sessions, N+1, transactions, connection pool.
• prompts/web-reviewer.md: FastAPI, aiohttp, Django, middleware, timeouts, request lifecycle, streaming.
• prompts/security-reviewer.md: authorization, tenant isolation, injection, deserialization, secrets, SSRF.

Review Contract

• Find concrete bugs, not generic advice.
• Bind every finding to code evidence and an execution path.
• Mark uncertain findings as 需要结合上下文确认.
• Do not output style comments unless they hide a real defect.
• If no clear high-risk issue is found, output exactly:

未发现明确高风险问题。
