Animation Shader Skill

Domain knowledge reference for animation-style shaders (Toon Shaders). Contains preset styles, feature lists, and reference mappings for popular shader libraries.

[!NOTE]

This skill contains domain knowledge only, not a workflow. Pair it with a workflow skill (e.g., OpenSpec, SpecKit) or an agent's plan mode for structured design flow.

Usage Modes

With Workflow Skill (Recommended)

When used with a workflow skill (e.g., OpenSpec, SpecKit) or in the plan mode of an agent, this skill serves as a domain knowledge plugin:

• During requirements/spec phases: Use the Presents section to identify the target style and map user requests to concrete feature sets
• During design/planning phases: Use the Feature List to look up all relevant references/ documents for each feature
• Key rule: For each identified feature, read ALL reference files listed — do not select just one

Knowledge Mode (Query)

When user requests to query knowledge for animation shaders, this skill provides preset styles and feature-to-reference mappings based on the task.
