Agent Skill

Shader Gen skill

shader-gen0xsline/OpenChatCutsrc/agent/skills/shader-gen/SKILL.md

AI shader generator for WebGL video effects, transitions, masks, and color grading (LUT / 调色 / 电影感 / film look). Use when the user wants a video effect (滤镜 / 特效), a transition (转场 / crossfade / wipe / cube / 3d), a mask (蒙版 / 遮罩 / reveal), a zoom / push-in (推近 / 推镜头), or a color grade — try the built-in effects (zoom, builtin LUTs) before generating a new shader.

Install the Shader Gen skill

Skills CLI (Claude Code, Codex, Cursor and others)

npx skills add https://github.com/0xsline/OpenChatCut --skill shader-gen

Claude Code, by hand (all projects)

git clone --depth 1 https://github.com/0xsline/OpenChatCut.git /tmp/OpenChatCut
mkdir -p ~/.claude/skills
cp -R /tmp/OpenChatCut/src/agent/skills/shader-gen ~/.claude/skills/shader-gen

For one project only, copy the folder into .claude/skills/ in that project instead. The agent picks it up when a task matches its description.

What it costs your context

Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.

Until it is used, shader-gen costs about 12× less than the median MCP server we measured (1,363 tokens on every turn). Installing all 31 skills from 0xsline/OpenChatCut would load 2,031 tokens of descriptions. Skills vs MCP study
