threejs-spectral-ocean SKILL.md skillA
threejs-spectral-ocean 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.
mdr add linegel/threejs-complete-set-of-skill/threejs-spectral-ocean@git:20260924.02ee59aPins git:20260924.02ee59a in mdr.lock. Pin the fingerprint instead.

Synthesize broad-band offshore seas with spectral FFT cascades in Three.js WebGPU/TSL. Use for homogeneous directional wind sea or swell, transported foam history, bounded CPU surface queries, or offshore forcing of a separate coastal model.
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
# Spectral Ocean Build a dimensioned random sea from directional variance density to one displaced, shaded surface. The spectral domain is a horizontally homogeneous periodic patch with one mean depth and one dispersion relation per cascade. ## 1. Gate the representation Choose from the required observable, not the desired look: | Observable | Owner | | --- | --- | | A few authored modes or exact cheap CPU queries | Parametric waves in `$threejs-water-optics` | | Bounded disturbances or explicit walls | Bounded heightfield in `$threejs-water-optics` | | Broad stochastic directional sea | This spectral FFT skill | | Depth-varying refraction, diffraction, breaking, run-up, or wet/dry fronts | Coastal branch in `$threejs-water-optics`; this skill may supply offshore forcing | | Overturning, entrained air, jets, or three-dimensional vortices | External free-surface solver | Select FFT cascades only when the visible wavelength band contains enough independent modes that direct summation is more expensive or visibly repetitive. Record the visible wavelength interval, footprint, tolerated phase/slope error, periodic repeat distance, interaction needs, and measured storage budget. …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-spectral-ocean@sha256:bff5e057b6055b7aThe line at the top of this page pins the label git:20260924.02ee59a, 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.
