Installation

No separate download: the skill runs the in-repo tool .claude/tools/cli/security-lint.cjs.

• Ensure Node.js (v18+) is installed: nodejs.org or winget install OpenJS.NodeJS.LTS (Windows), brew install node (macOS).
• From the project root, the script is invoked automatically; no extra install steps.

Cheat Sheet & Best Practices

AST-based validation: Use ESLint (or equivalent) with selectors/patterns; rules listen for specific node types. Prefer existing community rules before writing custom ones; custom rules need meta (type, fixable, schema) and create.

Process: Check naming (camelCase/PascalCase/snake_case), indentation, import order, function/class structure, comment style. Run in pre-commit and CI; provide auto-fix where possible.

Hacks: Use --fix for auto-fixable rules; combine with security-lint for policy. Define rule metadata clearly for docs and tooling. Use AST selectors for precise pattern matching (node type, attributes, child/sibling).

Certifications & Training

ESLint: Use in project, custom rules, selectors. No cert; skill data: AST-based validation, pre-commit/CI, auto-fix, naming/indent/imports.
