What problem does it solve?
This skill helps you identify security weaknesses and prevent production incidents by systematically reviewing authentication, authorization, input handling, secrets management, headers, and common OWASP Top 10 risks.
Core Features & Use Cases
- Threat-aware security review: Evaluates authorization (IDOR, horizontal/vertical escalation), authentication (brute force, session fixation), and business-logic abuse with an evidence-first mindset.
- Production hardening guidance: Provides concrete configuration baselines for security headers, cookies, CORS/CSRF, rate limiting, and secure file upload controls.
- Framework coverage: Tailored checklists for Laravel, Next.js/Node.js, and Svelte/SvelteKit, plus a structured penetration-testing-style checklist (without running exploits).
- L5 acceptance gates & safe output: Forces findings to be tied to exploitability/impact and validated by remediation verification steps, avoiding claims without evidence.
Quick Start
Use the security-hardening skill to review the codebase and configs for authentication, authorization, injection, file uploads, headers, and secrets handling, then output an evidence-based security review with prioritized fixes and verification steps.
