shader-dev SKILL.md skillB
shader-dev from martgueritainaccurate875/skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add martgueritainaccurate875/skills/shader-dev@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Comprehensive GLSL shader techniques for creating stunning visual effects — ray marching, SDF modeling, fluid simulation, particle systems, procedural generation, lighting, post-processing, and more.
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 martgueritainaccurate875/skills/shader-dev@sha256:7d3cc9d69da2b598The 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.
