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

Return a structured report in this exact format:

markdown
