Code Quality & Security Checks#

Run comprehensive project checks and fix all issues by priority.

Use Cases#

Use when users need "check code", "run check", "fix lint errors", or "code quality check".

Core Task#

Run the project check command and resolve all errors. Loop: check → fix → re-check until all pass.

Important Rules#

• Do not commit any code
• Do not change version numbers
• Only fix issues identified by checks

Workflow#

1. Run the check command
2. Analyze output for errors and warnings
3. Fix by priority:
   • 🔴 Build-breaking errors (highest priority)
   • 🔴 Test failures
   • 🟡 Linting errors
   • 🟢 Warnings
4. Re-run checks after each fix
5. Continue until all checks pass

Multi-Project Types#

• JavaScript/TypeScript: npm run check or yarn check
• Python: black → isort → flake8 → mypy
• Rust: cargo check → cargo clippy
• Go: go vet → golint
• Swift: swift-format → swiftlint

If the project has no check script, execute the above commands individually.
