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
