snowglider

Engineering discipline and hard-won lessons for developing the SnowGlider game (Three.js + TypeScript + Vite skiing sim in this repo). Use this skill whenever you add, change, refactor, or review code under src/, tests/, docs/, index.html, or the CI/Firebase config — especially anything touching physics, the game loop, terrain, trees/scenery, snow, avalanche, camera, jumps, controls, snowman, audio/sfx, scoring, Firebase/auth, teardown/dispose, or the test harnesses. It encodes the invariants the codebase enforces (determinism, byte-identical no-input physics, seeded-RNG neutrality, fixed-timestep frame-rate independence, teardown safety, automation gating) and the recurring bug classes that Codex review and past regressions keep catching, so changes don't break skiing physics, collision, test streams, or the GitHub Pages deploy.

Comprehensive guide for developing WebGPU-enabled Three.js applications using TSL (Three.js Shading Language). Covers WebGPU renderer setup, TSL syntax and node materials, compute shaders, post-processing effects, and WGSL integration. Use this skill when working with Three.js WebGPU, TSL shaders, node materials, or GPU compute in Three.js.
