Code Quality Audit

Find code quality issues. **NOT for security (use security-auditor) or runtime bugs (use bug-auditor).**

Output to `.claude/audits/AUDIT_CODE.md`.

Status Block (Required)

Every output MUST start with:

---
agent: code-auditor
status: COMPLETE | PARTIAL | SKIPPED | ERROR
timestamp: [ISO timestamp]
duration: [seconds]
findings: [count]
files_scanned: [count]
any_count: [count]
console_log_count: [count]
errors: []
skipped_checks: []

Scope (NON-OVERLAPPING)

**code-auditor checks:**

• Type safety (any usage, unsafe assertions)
• Code complexity (function length, nesting depth)
• Maintainability (file size, code duplication)
• Consistency (naming, patterns, API shapes)
• Dead code and unused imports
• Console.log/debug statements
• TODO/FIXME accumulation
• DRY violations

**Does NOT check (use other agents):**

• SQL injection, XSS, secrets → security-auditor
• Empty catch blocks, resource leaks → bug-auditor
• Performance, bundle size → perf-auditor

Check

**Type Safety**

• any usage (should be near zero)
• Unsafe type assertions (as unknown as X)
• Missing return types on public functions
• Implicit any from untyped imports
• Non-null assertions (!) overuse

**Complexity**

• Functions over 50 lines
• Nesting over 3 levels deep
• Cyclomatic complexity > 10
• Too many parameters (>4)
• Complex conditionals

**Maintainability**

• God files (>500 lines)
• Duplicate logic across files
• Magic numbers/strings
• Unused exports/imports
• Dead code paths

**Consistency**

• Inconsistent naming conventions
• Mixed async patterns (callbacks vs promises)
• API response shape inconsistency
• Inconsistent error shapes
• Mixed import styles

**Code Hygiene**

• Console.log in production code
• TODO/FIXME accumulation (>20)
• Commented-out code
• Unused variables
• Debug code left in

Grep Patterns

# Type safety
grep -rn ": any\|: any\[\]" src --include="*.ts" --include="*.tsx" | wc -l
grep -rn "as unknown as\|as any" src --include="*.ts" --include="*.tsx" | head -10
grep -rn "!\." src --include="*.ts" --include="*.tsx" | head -10

# Complexity - long files
find src -name "*.ts" -o -name "*.tsx" | xargs wc -l 2>/dev/null | sort -n | tail -10

# Code hygiene
grep -rn "console.log\|console.debug\|console.info" src --include="*.ts" --include="*.tsx" | wc -l
grep -rn "TODO\|FIXME\|HACK\|XXX" src --include="*.ts" --include="*.tsx" | wc -l
grep -rn "// .*import\|// .*const\|// .*function" src --include="*.ts" --include="*.tsx" | head -10

# Consistency
grep -rn "async.*callback\|\.then.*async" src --include="*.ts" | head -5

# Duplicate patterns
grep -rn "email.*@.*\." src --include="*.ts" | head -10
grep -rn "\.test\s*(" src --include="*.ts" | head -10

# Magic numbers
grep -rn "[^0-9a-zA-Z_][0-9]\{3,\}[^0-9a-zA-Z_]" src --inc
