Lint And Validate

name: lint-and-validate description: Automatic quality control, linting, and static analysis procedures. Use after every code modification to ensure syntax correctness and project standards. Triggers onKeywords: lint, format, check, validate, types, static analysis.

Lint and Validate Skill

MANDATORY: Run appropriate validation tools after EVERY code change. Do not finish a task until the code is error-free.

Automated Quality Audit (V2)

Maestro includes a comprehensive audit script that covers style, logic, and security:

python scripts/lint_check.py <file_path>

Procedures by Ecosystem

Node.js / TypeScript

1. Lint/Fix: npm run lint or npx eslint "path" --fix
2. Types: npx tsc --noEmit
3. Security: npm audit --audit-level=high

Python

1. Linter (Ruff): ruff check "path" --fix (Fast & Modern)
2. Security (Bandit): bandit -r "path" -ll
3. Types (MyPy): mypy "path"

The Quality Loop

1. Write/Edit Code
2. Run Audit: python scripts/lint_check.py <path>
3. Analyze Report: Check the "FINAL AUDIT REPORT" section.
4. Fix & Repeat: Submitting code with "FINAL AUDIT" failures is NOT allowed.

Error Handling

• If lint fails: Fix the style or syntax issues immediately.
• If tsc fails: Correct type mismatches before proceeding.
• If no tool is configured: Check the project root for .eslintrc, tsconfig.json, pyproject.toml and suggest creating one.

Strict Rule: No code should be committed or reported as "done" without passing these checks.
