lint-and-validate
Automatic code quality checks and validation across Node.js, TypeScript, and Python projects.
- Runs linting, type checking, and security audits with ecosystem-specific tools (ESLint/TypeScript for Node.js, Ruff/MyPy/Bandit for Python)
- Enforces a mandatory quality loop: write code, run audit, analyze report, fix issues, and repeat until all checks pass
- Includes helper scripts for unified lint checking and type coverage analysis across project paths
- Blocks code submission until all validation checks pass, preventing errors from reaching production
Lint and Validate Skill
MANDATORY: Run appropriate validation tools after EVERY code change. Do not finish a task until the code is error-free.
Procedures by Ecosystem
Node.js / TypeScript
- Lint/Fix:
npm run lintornpx eslint "path" --fix - Types:
npx tsc --noEmit - Security:
npm audit --audit-level=high
Python
- Linter (Ruff):
ruff check "path" --fix(Fast & Modern) - Security (Bandit):
bandit -r "path" -ll - Types (MyPy):
mypy "path"
The Quality Loop
- Write/Edit Code
- Run Audit:
npm run lint && npx tsc --noEmit
