nixos-config

Hyprland/Steam gaming launch-option workflow for this NixOS machine. Use whenever the user asks for best settings for a game, Steam/Proton launch options, gamescope, MangoHud/MangoApp, VRR/adaptive sync, fullscreen game focus/hover/cursor issues, Rocket League-like settings, or says to optimize a game such as Black Ops 3 on Hyprland.

Use when file search or content grep is needed in a git-indexed directory and the fff MCP server is available.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
