Unity Shader Skills

Before calling any skill in this module: if you are about to call a skill with parameters guessed from its name or description, STOP — read this file (or fetch its schema via GET /skills/recommend?includeSchema=true) first. If you already have the parameter definitions from recommend/schema, you may proceed straight to dryRun.

Triggers

• Creating or editing handwritten shaders
• Listing or finding .shader files
• Inspecting properties/keywords
• 创建或编辑手写 shader、列出/查找 .shader 文件、检查属性与关键字

Unity Shader Skills

Work with .shader HLSL/ShaderLab files (create from templates, read source, list, find, get keywords/properties/variants, check errors, delete, toggle global keywords). For node-based ShaderGraph use the shadergraph module.

Operating Mode

• Query skills (shader_read, shader_list, shader_find, shader_get_properties, shader_check_errors, shader_get_keywords, shader_get_variant_count) are SkillMode.SemiAuto — they run in all three modes without grant.
• Mutating skills (shader_create, shader_create_urp, shader_set_global_keyword) are SkillMode.FullAuto — under Approval they need user grant (grant triggers one server-side execute returning the result); under Auto / Bypass they execute directly.
• shader_delete carries SkillOperation.Delete and is auto-forbidden in Approval / Auto modes (NeverInSemi). Only Bypass or the user-managed Allowlist can run it.

Guardrails

DO NOT (common hallucinations):

• shader_set_property does not exist → use material_set_float/material_set_color/etc. on the material, not the shader
• shader_apply / shader_assign do not exist → use material_set_shader to change a material's shader
• shader_get_properties returns shader property definitions (name/type/range), not current values → for material instance values use material_get_properties
• Shader names are case-sensitive and path-like: "Standard", "Universal Render Pipeline/Lit", not "standard" or "URP Lit"

Routing:

• For material property changes → use material module
• For shader keyword control → material_set_keyword (material module)
• For global shader keywords → shader_set_global_keyword (this module)
