Code Health Check
SkillAI & modelsPerform a comprehensive code health check on a directory. Use when the user asks to analyze code quality, find issues, or get a health report.
Available today. Use it from your connected AI after setup.
No other account needed.
Connect ahel once, and every AI you use reads what you have installed.
Then ask your AI: use the Code Health Check skill
What this skill tells your AI
The instructions your AI receives, as published by huangjia2019/claude-code-engineering in 04-Skills/projects/07-skill-fork-demo/.claude/skills/code-health-check/SKILL.md and read by ahel’s review.
Analyze the codebase at $ARGUMENTS and produce a structured health report.
Checks to Perform
1. File Organization
- Are files reasonably sized? (Flag files > 200 lines)
- Is the directory structure logical?
- Any files that look misplaced?
2. Error Handling
- Are async operations wrapped in try/catch?
- Are errors propagated correctly (not swallowed)?
- Is there a global error handler?
3. Security Basics
- Any hardcoded secrets, API keys, or passwords?
- Any use of
eval()or similar dangerous functions? - Are user inputs validated before use?
4. Code Quality
- Any obvious code duplication (similar blocks in multiple files)?
- Any unused variables or imports?
- Are function signatures reasonable (not too many parameters)?
5. Dependency Hygiene
- Are all imported modules actually used?
- Any circular dependencies?
Severity Levels
Use these to categorize issues:
| Severity | Meaning | Example |
|---|---|---|
| CRITICAL | Must fix immediately | Hardcoded secrets, SQL injection |
| WARNING | Should fix soon | Missing error handling, large files |
| INFO | Nice to improve | Minor duplication, naming conventions |
Output Format
Return a structured report in this exact format:
# Code Health Report: {directory}

## Critical Issues
{list each with file:line and description}
## Warnings
{list each with file:line and description}
## Info
{list each with file:line and description}
## Recommendations
{top 3 actionable recommendations}
