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.
