Skill UI

This skill provides comprehensive principles for developing multiplayer games, covering essential topics from networking architecture (Dedicated, P2P, Host-based) to advanced synchronization techniques. It details how to handle latency via prediction, interpolation, and lag compensation, optimize bandwidth using delta compression, and implement robust security measures like server authority and anti-cheat systems. Ideal for developers building real-time online experiences.

This skill provides deep security review for GitHub Actions workflow files. It focuses on the unique Actions threat model—identifying vulnerabilities like script injection via ${{ }} interpolation, privilege escalation from triggers (e.g., pull_request_target), and ensuring least-privilege permissions for CI/CD pipelines. Use it to audit, secure, or harden existing workflows, preventing attacks from untrusted inputs and supply chain risks.

A comprehensive guide to tuning game physics parameters, including mass, gravity, drag, and continuous collision detection (CCD). It addresses common stability issues like jitter and tunneling by correctly separating the fixed-timestep simulation (physics updates) from the variable-rate rendering (visual updates) using interpolation. Essential for creating predictable and responsive game motion across various hardware.
