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 make lint (which executes trunk check -a) to list current violations.
2. Analyze: Examine the output from Trunk, focusing on the file path, line number, and error message.
3. Fix:
   • For formatting issues, run make format (which executes trunk fmt -a).
   • For linting violations, apply the minimum necessary change to the source code to resolve the error.
4. Verify: Re-run make lint.
   • 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 make lint.
• Reached max iteration limit (default: 5).

Examples

Scenario: Fixing a formatting violation

1. make lint reports formatting issues in src/your_package/main.py.
2. Agent runs make format.
3. make lint now passes.
