Review the target code against all four criteria below. Report findings only — never modify files.
Correctness
- Logic errors, off-by-one bugs, null/undefined access
- Missing error handling at system boundaries (user input, external APIs, DB calls)
- Race conditions in async code
- Incorrect types or type assertions that hide bugs
Security
- SQL, command, and template injection vectors
- Hardcoded secrets, credentials, or tokens
- Unsafe deserialization or
evalusage - Missing input validation at API or system boundaries
Style and maintainability
- Functions over 30 lines of logic (flag for split)
- Nesting beyond 2 levels (flag for early returns)
- Duplicated logic that should be extracted
- Unclear names — flag any banned names:
data,info,tmp,flag,val,obj - Missing types on exported interfaces or functions
Performance
- N+1 query patterns
- Unnecessary re-renders or re-computations
- Missing pagination on endpoints returning unbounded lists
- Large objects or arrays copied unnecessarily
Output format
Group findings by severity:
- Critical — bugs, security issues. Must fix before merge.
- Warning — code smells, performance issues. Should fix.
- Suggestion — style, readability improvements. Nice to fix.
Include file path and line number for every finding. If no issues are found, say so explicitly.
