# Lint And Fix > 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. Use when this capability is needed. - Skill: `tomevault-io/lint-and-fix-3` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/lint-and-fix-3` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/lint-and-fix-3/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/lint-and-fix-3 --- # Lint and Fix Loop: Trunk ## Purpose An autonomous loop for the agent to identify, fix, and verify linting and formatting violations using [Trunk](https://trunk.io). ## Loop Logic 1. **Format**: Run `pnpm format` (which executes `trunk fmt`) to automatically fix trivial formatting issues. 2. **Identify**: Run `pnpm lint` (which executes `trunk check`) to list any remaining violations. 3. **Analyze**: Examine the output from Trunk, focusing on the file path, line number, and error message. Refer to [../common-references/troubleshooting.md](../common-references/troubleshooting.md) for environment or runtime issues. 4. **Fix**: Apply the minimum necessary change to the source code to resolve the reported linting violations. 5. **Verify**: Re-run the loop (starting from **Format**) until all issues are resolved. - If `pnpm lint` passes: Finish. - If it fails: Analyze the new failure and repeat the loop. ## Termination Criteria - No more errors reported by `pnpm lint`. - Reached max iteration limit (default: 5). ## Examples ### Scenario: Fixing violations in a modified file 1. Agent runs `pnpm format` to ensure consistent style. 2. Agent runs `pnpm lint` and finds a linting violation in `src/index.ts`. 3. Agent analyzes the error and applies a manual fix. 4. Agent runs `pnpm format` again (part of the loop). 5. Agent runs `pnpm lint` and it now passes. ## Resources - [Trunk CLI Reference](../common-references/trunk-commands.md): Common commands for linting and formatting. - [Trunk Documentation](https://docs.trunk.io/): Official documentation for the Trunk CLI. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/yu-iskw) — claim your Tome and manage your conversions.
