Code Check

Run project quality checks and security reviews, fixing all errors by priority until all pass.

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

Check Types

Type	Description	JS/TS	Python	Rust	Go
Lint	Code style & syntax	ESLint	flake8	clippy	golint
Type Check	Type errors	tsc	mypy	cargo check	go vet
Tests	Failing cases	jest/vitest	pytest	cargo test	go test
Security	Vulnerability detection	npm audit	bandit	cargo audit	govulncheck
Formatting	Style consistency	prettier	black	rustfmt	gofmt
Build	Compilation errors	tsc --noEmit	—	cargo check	go build

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.
