Code Quality Enforcement

Canonical configuration patterns for JavaScript/TypeScript and Python code quality tooling. Auto-detect project type, generate config files, and integrate with CI.

When to Use This Skill

• Setting up linting and formatting for a new project
• Reviewing or upgrading existing code quality configs
• Generating ESLint, Prettier, Ruff, or mypy configuration files
• Adding lint/format steps to GitHub Actions CI
• Diagnosing why a linter isn't catching issues (wrong config, missing rules)
• Migrating from legacy tooling (TSLint → ESLint, Black/flake8/isort → Ruff)

Auto-Detection

Identify the project stack from these markers before generating configs:
