Linting

Linter detection

Check package.json devDependencies:

• @biomejs/biome → npm run check / fix: npm run check --write
• oxlint → npm run lint / fix: npm run lint --fix
• eslint (default) → npm run lint / fix: npm run lint:fix

Workflow

1. Detect linter from devDependencies
2. Run lint command
3. For fixes: run fix variant (only when requested)
4. Report file:line references for all errors

Rules

• Use project's package.json scripts
• Never use npx directly
• Don't auto-fix unless requested

Error Handling

• If no lint script found in package.json → check scripts for alternative names (check, lint:check); report if none exist
• If linter exits with parse errors → report each file-level parse error separately with file:line
• If linter config file is missing → report which config file is expected and stop
