aget-lint-code

Run code linting and formatting checks on files or directories. Auto-detects linter configuration and reports issues by severity.

Instructions

When this skill is invoked:

1. Detect Linter Configuration

   • Python: ruff, flake8, pylint (pyproject.toml, setup.cfg)
   • JavaScript: eslint (.eslintrc.*)
   • Go: golangci-lint (.golangci.yml)
   • YAML: yamllint

2. Execute Linter

   • Use project configuration
   • Target specified files or all
   • Capture output

3. Process Results

   • Categorize by severity (error, warning, info)
   • Extract file locations
   • Count issues

4. Report Findings

   • Summary by severity
   • Issue details with locations
   • Fix suggestions if available

Execution Commands

# Python (ruff)
ruff check [path] --output-format=text

# Python (flake8)
flake8 [path]

# JavaScript (eslint)
npx eslint [path] --format stylish

# Go
golangci-lint run [path]

# YAML
yamllint [path]

Output Format

## Lint Results

### Summary

| Severity | Count |
|----------|-------|
| Errors | [N] |
| Warnings | [N] |
| Info | [N] |
| **Total** | [N] |

### Status: [CLEAN/ISSUES FOUND]

### Issues by File

#### [filename.py]

| Line | Severity | Rule | Message |
|------|----------|------|---------|
| [N] | Error | [E001] | [Description] |
| [N] | Warning | [W002] | [Description] |

### Auto-fixable

[N] issues can be auto-fixed with `--fix` flag.

### Recommended Actions

1. [Fix critical errors first]
2. [Address warnings]

Constraints

• C1: NEVER apply auto-fixes without explicit --fix flag — lint is read-only by default
• C2: NEVER ignore configuration files — project configuration must be respected
• C3: NEVER fail silently when linter is misconfigured — configuration errors must be surfaced
