This expert playbook covers advanced techniques for testing HTTP request smuggling and desynchronization vulnerabilities. It is critical when front proxies, CDNs, or load balancers disagree with the origin server on message framing (Content-Length vs Transfer-Encoding), or during protocol downgrades (HTTP/2 to HTTP/1). Use this to uncover deep security flaws like WAF bypass and session hijacking.

A comprehensive guide for cryptanalysts detailing advanced attack vectors against RSA cryptography. This playbook covers factorization methods, small exponent exploits (e.g., Hastad Broadcast), lattice-based attacks (Wiener's, Boneh-Durfee), and methods exploiting protocol weaknesses like padding oracles. Essential for CTF challenges and authorized security assessments.

A comprehensive playbook detailing expert techniques to escape multiple types of restricted environments, including Python pyjail, Docker containers, seccomp filters, and browser rendering processes. It covers advanced exploitation vectors like namespace escapes, kernel exploits, and built-in function bypasses for achieving code execution.

This expert playbook details advanced techniques for establishing secure network tunnels and pivoting through compromised hosts. It covers various methods like SSH (Local, Remote, Dynamic, Jump), Chisel, Ligolo-ng, socat, and ProxyChains. Use this guide to bypass network restrictions, establish persistent access, and perform multi-layered lateral movement within restricted environments.

This skill provides comprehensive testing for WebSocket APIs, covering protocol basics, Cross-Site WebSocket Hijacking (CSWSH), and common security flaws. Use it when testing applications that rely on real-time communication, chat features, or persistent data streams. It validates Origin checks, session binding, and message integrity.

This skill guides the planning and review process for complex home or small-lab network changes. It covers creating staged migration plans for VLAN segmentation, implementing local DNS resolvers (like Pi-hole), setting up secure VPN access, and ensuring network safety through detailed inventory checks and rollback procedures. It emphasizes security best practices and trust zoning.

A risk-paranoid, mandatory review process designed to interrogate any plan that touches sensitive customer data, regulatory compliance, or production access. It forces consideration of critical security pillars including STRIDE threat modeling, blast radius quantification, detection mechanisms (MTTD), incident response runbooks, regulatory notification windows, and third-party vendor security posture. Essential before deploying features handling PII, PHI, or before compliance audits (SOC 2, HIPAA, GDPR).

A comprehensive guide on segmenting a home network using VLANs to dramatically enhance security. Learn how to isolate different device types—such as IoT gadgets, guests, and servers—from main PCs, preventing cross-segment malware spread and unauthorized communication. Covers setup steps for UniFi, pfSense, and OPNsense.

A comprehensive guide to setting up a fast and secure WireGuard VPN server for remote access to your home network (homelab). Learn keypair generation, advanced Linux firewall (iptables) rules, and how to manage different tunneling modes (split vs. full tunnel) for optimal performance.

A comprehensive guide for securing container images and runtime environments. Covers best practices from Dockerfile authoring (minimal base images, multi-stage builds, non-root users) through advanced runtime enforcement (seccomp, AppArmor) and Kubernetes security controls. Essential for production hardening and maintaining supply chain integrity.

This skill provides comprehensive management for Opencode's permission system. It allows users to review currently always-allowed commands, suggest safe read-only commands, and configure granular access controls using allow/deny/ask patterns. It is essential for optimizing security, performing system audits, and managing the operational scope of the agent.

A structured, multi-phase skill that systematically audits and provides actionable fixes for all four Lighthouse pillars: Performance, Accessibility, Best Practices, and SEO. It analyzes Core Web Vitals, render-blocking resources, security headers, and ARIA compliance to significantly boost site speed and quality.
