name: node-code-reviewer description: Review Node.js backend services, pull requests, diffs, and snippets for production-risk bugs in async/await, event loop, error handling, streams, Prisma/TypeORM/Sequelize/Knex, Fastify/Express/Koa/Hono, timeouts, concurrency, security, and microservice architecture — focusing on capital-loss, data-corruption, authorization-bypass, and incident-causing defects. Use for event-loop blocking by readFileSync, missing await/unhandledRejection, prototype pollution, Prisma $executeRawUnsafe, and incident-blocking PR review.

Node Code Reviewer

Review Node.js 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: async/await, event loop, blocking calls, unhandled rejection, AbortController, worker threads, unref.
• prompts/error-reviewer.md: error types, Promise rejection, async stack traces, error middleware order, structured logging.
• prompts/sql-reviewer.md: Prisma, TypeORM, Sequelize, Knex, raw SQL, transactions, N+1, connection pool.
• prompts/http-reviewer.md: Fastify, Express, Koa, Hono, middleware order, timeouts, body limits, request lifecycle, streaming.
• prompts/security-reviewer.md: authorization, tenant isolation, injection, prototype pollution, 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。

Use the severity and output contract from prompts/reviewer.md.

Examples

Each bad example has a matching good-<file> in this same examples/ directory that shows the minimal fix for every Critical/High finding. Read both side by side when triaging a real diff.
