/configure:linting

Check and configure linting tools against modern best practices.

When to Use This Skill

Use this skill when...	Use another approach when...
Setting up modern linting (Biome, Ruff, Clippy)	Just running linter (use /lint:check skill)
Migrating from ESLint/Prettier to Biome	Linters already properly configured
Validating linter configuration	Fixing specific lint errors (run linter and fix)
Ensuring language-specific best practices	Simple script with no linting needs
Configuring pre-commit lint integration	Debugging linter issues (check linter logs)

Context

• Project root: !pwd
• Biome config: !find . -maxdepth 1 -name 'biome.json' -o -name 'biome.jsonc'
• Ruff config: !find . -maxdepth 1 -name 'pyproject.toml' -exec grep -l 'tool.ruff' {} +
• Clippy config: !find . -maxdepth 1 -name 'Cargo.toml' -exec grep -l 'lints.clippy' {} +
• Legacy linters: !find . -maxdepth 1 \( -name '.eslintrc*' -o -name '.flake8' -o -name '.pylintrc' \)
• Package files: !find . -maxdepth 1 \( -name 'package.json' -o -name 'pyproject.toml' -o -name 'Cargo.toml' \)
• Pre-commit config: !find . -maxdepth 1 -name '.pre-commit-config.yaml'
• CI workflows: !find . -path '*/.github/workflows/*' -maxdepth 3 -name '*.yml'

Parameters

Parse from $ARGUMENTS:

• --check-only: Report linting compliance status without modifications
• --fix: Apply all fixes automatically without prompting
• --linter <biome|ruff|clippy>: Override auto-detection and force specific linter

Modern linting preferences:

• JavaScript/TypeScript: Biome (unified linter + formatter, fast)
• Python: Ruff (replaces flake8, isort, pyupgrade)
• Rust: Clippy with workspace lints
