lint-and-fix

name: lint-and-fix description: Run linters and fix violations, formatting errors, or style mismatches using Trunk. Use when code quality checks fail, before submitting PRs, or to repair "broken" linting states.

Lint and Fix Loop: Trunk

Purpose

An autonomous loop for the agent to identify, fix, and verify linting and formatting violations using Trunk.

Loop Logic

1. Identify: Run pnpm lint (which executes trunk check -y and eslint .) to list current violations. For a comprehensive check across the entire project, use pnpm lint:all (executes trunk check --all and eslint .). You can also run pnpm lint:eslint for focused ESLint checks.
2. Analyze: Examine the output from Trunk or ESLint, focusing on the file path, line number, and error message. Refer to ../common-references/troubleshooting.md for environment or runtime issues.
3. Fix:
   • For formatting issues, run pnpm format (which executes trunk fmt). To format all files in the project, use pnpm format:all.
   • For linting violations, apply the minimum necessary change to the source code to resolve the error. You can use pnpm format:eslint to automatically fix many ESLint violations.
   • For security-specific checks, you can run pnpm run lint:security.
4. Verify: Re-run pnpm lint (or pnpm lint:all or pnpm lint:eslint depending on what you used initially).
   • If passed: Move to the next issue or finish if all are resolved.
   • If failed: Analyze the new failure and repeat the loop.

Termination Criteria

• No more errors reported by pnpm lint, pnpm lint:all, or pnpm lint:eslint.
• Reached max iteration limit (default: 5).

Examples

Scenario: Fixing a formatting violation

1. pnpm lint reports formatting issues in src/index.ts.
2. Agent runs pnpm format.
3. pnpm lint now passes.

Scenario: Performing a full project cleanup

1. Agent runs pnpm lint:all to check every file.
2. Several formatting issues are found.
3. Agent runs pnpm format:all to fix them all at once.
4. pnpm lint:all now passes.

Scenario: Fixing ESLint violations

1. pnpm lint:eslint reports several linting errors.
2. Agent runs pnpm format:eslint.
3. pnpm lint:eslint now passes or shows fewer errors that require manual fixing.
