shaders skillB

shaders is agent-read markdown (skill) from thrashr888/alchemy: Use when editing, adding, or reviewing a WebGL shader mode in src/components/DitherBackground.tsx (the notebook backdrop, one GLSL program with 17 theme-driven modes) or src/components/settings/TileShader.tsx (Activity tile washes), or when a theme in src/lib/themes.ts gets a new `shader` variant. Renders the real GLSL in a browser harness so the change is seen before it ships..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add thrashr888/alchemy/shaders@git:20260901.699d9ae
Exact content
mdr add thrashr888/alchemy/shaders@sha256:bcf00d44a76d266c

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
