threejs-water-optics SKILL.md skillA
threejs-water-optics from linegel/threejs-complete-set-of-skill is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Solve bounded and coastal water in Three.js WebGPU/TSL. Use for parametric waves, local heightfields, bathymetric wave transport, wet/dry shallow water, two-way body coupling, external free-surface presentation, or water optics and offshore handoffs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Water Optics Select the least complex water representation that owns the requested observable, then derive displacement, derivatives, foam, wetness, and optical transport from that state. ## 1. Gate the water model | Required observable | Representation | Invalid when | | --- | --- | --- | | Static surface and bathymetry; only bottom visibility, refraction, attenuation, or caustics matter | Static bathymetry plus optical transport | Surface motion, waterline motion, or interaction is required | | Prescribed coast-following crests; no flow or interaction claim | Coast SDF plus prescribed shoreline phase | Diffraction, run-up, bulk flow, or changing wet/dry topology matters | | Few coherent waves; no local disturbance | Parametric displaced surface | Broad stochastic bands or dense interaction dominate | | Bounded weak waves and local impulses | Linear heightfield | Breaking, bulk flow, or wet/dry topology matters | | Fixed bathymetry; phase-averaged shoaling/refraction | Wave action or rays | Diffraction, interference, or instantaneous crest parity matters | …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-water-optics@sha256:a057e97e34d98793The line at the top of this page pins the label git:20260924.79f8dd0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
