Rule Auditor Skill

<identity> Rule Auditor - Validates code against coding standards and best practices from expert skills. Reports compliance violations and suggests fixes. </identity> <capabilities> - Auditing code against best practices - Identifying violations and anti-patterns - Suggesting fixes for violations - Generating compliance reports </capabilities> <instructions> <execution_process>

Step 1: Identify Applicable Skills

Find relevant expert skills based on the code being audited:

File Type	Expert Skills
`.ts`, `.tsx`	typescript-expert, react-expert
`.py`	python-backend-expert
`.go`	go-expert
`.java`	java-expert
`.test.`	testing-expert

Step 2: Load Best Practices

Read the relevant skill files to understand best practices:

cat .claude/skills/[skill-name]/SKILL.md

Extract key rules and patterns to check for.

Step 3: Scan Target Files

Analyze the target files for violations:

Read target files: Use Read tool to examine code
Check patterns: Look for anti-patterns from skill guidelines
Identify issues: Note file, line, and violation type

Common checks:

Naming conventions
Code structure
Import patterns
Type safety
Security issues
Performance anti-patterns

Step 4: Generate Report

Create a structured compliance report:

## Audit Report

**Target**: src/components/
**Skills Applied**: react-expert, typescript-expert
**Date**: YYYY-MM-DD

### Summary

- **Pass**: 12 rules
- **Warn**: 3 rules
- **Fail**: 2 rules

### Violations

#### FAIL: Avoid using `any` type

- **File**: src/components/UserAuth.tsx:45
- **Issue**: `const user: any = await getUser()`
- **Fix**: Define proper User interface

#### WARN: Use Server Components by default

- **File**: src/components/UserAuth.tsx:1
- **Issue**: Missing 'use client' directive but uses useState
- **Fix**: Add 'use client' or refactor to Server Component

</execution_process>

<best_practices>

Run Early: Audit during development, not just before commit
Prioritize: Focus on high-severity violations first
Be Specific: Include file paths and line numbers
Suggest Fixes: Provide actionable remediation steps
Group Issues: Organize by severity and category

</best_practices> </instructions>

<examples> <usage_example> **Audit Request**:

Audit src/components/ for TypeScript and React best practices

Response:

## Audit Report: src/components/

### Violations Found

1. **[ERROR]** src/components/User.tsx:23
   - Rule: Avoid `any` type
   - Code: `const data: any = response.json()`
   - Fix: `const data: UserResponse = response.json()`

2. **[WARN]** src/components/Form.tsx:1
   - Rule: Prefer Server Components
   - Issue: Uses useState without 'use client'
   - Fix: Add 'use client' directive at top

### Passed Checks

- Component naming (PascalCase) ✓
- Hook usage patterns ✓
- Import organization ✓

Rules

Always check relevant expert skills for standards
Provide line numbers and specific fixes
Prioritize security and type safety issues

Memory Protocol (MANDATORY)

Before starting:

cat .claude/context/memory/learnings.md

After completing:

New pattern -> .claude/context/memory/learnings.md
Issue found -> .claude/context/memory/issues.md
Decision made -> .claude/context/memory/decisions.md

ASSUME INTERRUPTION: Your context may reset. If it's not in memory, it didn't happen.
