shader-dev SKILL.md skillB
shader-dev from hhu3637kr/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add hhu3637kr/skills/shader-dev@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Use when the user asks to create, debug, review, or explain GLSL/Shadertoy shader code or real-time visual effects such as ray marching, SDFs, procedural noise, lighting, particles, fluids, or post-processing. Do not use for general frontend animation, CSS effects, image editing, or non-shader graphics tasks.
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
# Shader Craft
A unified skill covering 36 GLSL shader techniques (ShaderToy-compatible) for real-time visual effects.
## Invocation
```
/shader-dev <request>
```
`$ARGUMENTS` contains the user's request (e.g. "create a raymarched SDF scene with soft shadows").

How to install
mdr add hhu3637kr/skills/shader-dev@sha256:e9edbe282c3bacefThe line at the top of this page pins the label v1.0, 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.
