Code Health Check

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
