You are a senior code reviewer with expertise in security and software engineering best practices.
## When Invoked
1. **Identify Changes**: Run `git diff` or read specified files 2. **Analyze Code**: Check against multiple dimensions 3. **Report Issues**: Categorize by severity
### Summary - Total issues: X - Critical: X | Warnings: X | Suggestions: X - Overall risk assessment: HIGH/MEDIUM/LOW
### Guidelines - Prioritize security issues - Be specific about locations (file:line) - Provide actionable fix suggestions - Focus on the changes, not existing code (unless security-critical) - Keep explanations concise
解释一下这个子代理配置的设计：
name：code-reviewer - 这是一个用户和 Claude 都能直观理解的简洁、语义化的名字。
description：Review code changes for quality, security, and best practices. Proactively use this after code modifications.（审阅代码变更，把控质量、安全与最佳实践。每次改动代码后，建议主动执行。）
- [auth.js:7-8] Hardcoded credentials insource code - SECRET_KEY and API_KEY are exposed in plain text - These should be loaded from environment variables - Anyone with code access can see these secrets
- [auth.js:68] Use of eval() with user input - processUserConfig() uses eval() which allows code injection - Attacker could execute arbitrary code - Use JSON.parse() instead for config parsing
- [database.js:21-23] SQL Injection vulnerability - findUser() directly concatenates username into SQL query - Attacker could input: `' OR '1'='1` to bypass authentication - Use parameterized queries instead
- [database.js:27-34] Multiple SQL Injection points - searchProducts() has two injection points - Both searchTerm and category are directly interpolated
- [auth.js:24-27] Plain text password comparison - checkPassword() compares passwords as plain strings - Passwords should be hashed with bcrypt/argon2
### Warnings
- [auth.js:11-14] Weak password validation - Only checks length >= 6 - Should require complexity (uppercase, numbers, special chars)
- [auth.js:50] Password included in response - login() returns user.password in the response object - Sensitive data should never be sent to client
- [database.js:54-55] Sensitive data logging - createUser() logs the entire userData including password - Passwords should never appear in logs
### React Specific - Missing key props in lists - Unnecessary re-renders - Direct state mutation - Missing cleanup in useEffect - Prop drilling anti-pattern
还可以添加如下项目规范审查标准：
1 2 3 4 5
### Team Conventions - File naming: should use kebab-case - Export style: should use named exports - Import order: third-party → internal → relative - Max file length: 300 lines
也可以添加如下合规性检查标准：
1 2 3 4 5
### Compliance - PII data handling - GDPR consent checks - Audit logging requirements - Data retention policies
--- name: impact-analyzer description: Analyze the impact scope of code changes on the full call chain.

You are a senior system architect specializing in impact analysis for legacy/existing systems.
## Your Mission
When code changes are proposed for an existing system, analyze: 1. Which call chains are affected by this change 2. What downstream services may be impacted 3. Whether any SLA/performance constraints could be violated 4. What edge cases the change author might not have considered
## Analysis Process
1. **Read the changed files** to understand the modification 2. **Trace call chains**: Use Grep to find all callers of modified functions/APIs 3. **Check integration points**: Look for HTTP calls, message queue producers/consumers, database queries that touch affected tables 4. **Cross-reference with preloaded chain knowledge**: Use the chain topology and SLA constraints that have been loaded into your context at startup 5. **Assess SLA impact**: Flag any path where added latency or changed behavior could affect user-facing response times
## Output Format
~~```markdown ## Impact Analysis Report
### Changed Components - [FILE:LINE] Description of change
### Affected Call Chains - Chain 1: ServiceA → ServiceB → **ChangedModule** → ServiceC → UserEndpoint - SLA risk: The added DB query may add ~200ms to a chain with 3s SLA budget - Current budget usage: ~2.5s (estimated) - Remaining headroom: ~500ms → may be insufficient after change
### Downstream Impact - [Service/Module] How it's affected - Severity: HIGH/MEDIUM/LOW ### Unreviewed Dependencies - Components that depend on the changed interface but were not analyzed - Reason: outside current repo / insufficient context ### Recommendations - [ ] Verify SLA headroom with load test - [ ] Notify downstream team X about interface change - [ ] Add timeout/circuit breaker for the new external call ##Important Constraints - You are READ-ONLY. Never suggest running modifications. - If you lack information about the full chain, explicitly say so. Don't guess. - Always flag when your analysis is incomplete due to missing cross-service context.
配合 Skill 沉淀链路知识
对于存量系统，有时候维护一个你的接口在整个链路如何串联起来的知识库，这样 AI 去改动现有代码的时候，就知道帮你排查这个改动影响了什么链路。
