What problem does it solve? Manually reviewing code for security flaws, performance bottlenecks, and quality issues is slow and inconsistent. This Skill provides a structured audit checklist that catches SQL injection, XSS, hardcoded secrets, N+1 queries, and code complexity problems in a single pass. ## Core Features & Use Cases - Security Scanning: Detects SQL injection, XSS, CSRF, command injection, path traversal, hardcoded credentials, and broken access control. - Performance Analysis: Identifies N+1 queries, unbounded loops, memory leaks, and blocking calls in async code. - Quality Review: Flags cyclomatic complexity above 10, deep nesting, magic numbers, missing types, and dead code. - Use Case: Before merging a pull request that touches authentication logic, run an audit to get a severity-ranked list of issues (HIGH/MEDIUM/LOW) with file and line references, plus concrete code fixes for the top three problems. ## Quick Start Audit the authentication module for security vulnerabilities and performance issues, then list findings by severity with fixes for the top issues.
