Lint & Validation

When to use this skill

• Setting up a new project's CI/CD or git hooks.
• Configuring ESLint, Prettier, PHP CodeSniffer, or Ruff.
• Fixing lint errors.

1. PHP

• Tools: PHP_CodeSniffer (PSR-12) or Laravel Pint.
• Command: composer lint (custom script) or ./vendor/bin/pint.
• Static Analysis: PHPStan (Level 5+) is recommended for logic errors.

2. JavaScript / TypeScript

• Tools: ESLint + Prettier.
• Config: Use strict configs (eslint:recommended, plugin:@typescript-eslint/recommended).
• Imports: Enforce sorted imports via eslint-plugin-simple-import-sort.

3. Python

• Tools: Ruff (replaces Flake8/Black/Isort).
• Config: Enable standard rules (E, F, I for imports).

4. Git Hooks

• Husky: Use Husky to run linters on pre-commit.
• Strategy: Lint only staged files (lint-staged) to keep commits fast.
