Lint And Fix

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.
