procedural-weather
by CK42BB
Generate dynamic procedural weather effects in Three.js using WebGPU compute with WebGL2 fallback. Covers rain (drizzle to monsoon), snow (flurries to blizzard), hail, fog and mist (ground fog, volumetric), lightning (bolt, sheet, cloud-internal), dust/sandstorms, wind-driven debris, rainbows, aurora borealis, and a weather state machine for smooth transitions. All precipitation uses GPU particle systems with collision, splashes, and accumulation. Provides per-effect lighting changes, ambient sound cue hints, and camera post-processing (wet lens, frost). Use when building weather systems, atmospheric effects, environmental ambience, climate simulation, or any scene needing dynamic weather. Triggers: "procedural weather", "rain effect", "snow particles", "lightning", "fog shader", "weather system", "storm", "blizzard", "sandstorm", "aurora", "rainbow", "precipitation", "weather transition", "wet lens".

groove
by mbilokonsky
[PLACEHOLDER - skill not yet fully defined] The groovy commutator is a formal detector for edge-of-chaos dynamics—systems where order of operations matters in structured (not random) ways. This is the signature of aliveness. J Dilla saw what Heisenberg saw, and it shows up in Class 4 cellular automata, jazz micro-timing, quantum mechanics, and semantic navigation.
