## Coverage Summary
| Category | Documented | Missing | Coverage |
|----------|------------|---------|----------|
| Functions | X | X | X% |
| API Routes | X | X | X% |
| Types | X | X | X% |

## Missing Documentation

### High Priority (Public APIs)

#### `src/lib/auth.ts`
- `verifyToken()` - Missing JSDoc
- `createSession()` - Missing param descriptions
- `refreshToken()` - Missing return type docs

### Medium Priority (Internal)
...

### Outstanding TODOs
| File | Line | Comment | Age |
|------|------|---------|-----|
| src/api/users.ts | 42 | TODO: Add rate limiting | Unknown |

## Recommendations
1. Add JSDoc to all exported functions
2. Create API.md with endpoint documentation
3. Address X high-priority TODOs

Execution Logging

After completing, append to `.claude/audits/EXECUTION_LOG.md`:

| [timestamp] | doc-auditor | [status] | [duration] | [findings] | [errors] |

Output Verification

Before completing:

1. Verify .claude/audits/AUDIT_DOCS.md was created
2. Verify file has content beyond headers
3. If no issues found, write "No documentation issues detected" (not empty file)
