Skills

shader_create

Create a shader file from template.

Parameter	Type	Required	Default	Description
shaderName	string	Yes	-	Shader name (e.g., "Custom/MyShader")
savePath	string	Yes	-	Save path
template	string	No	"Unlit"	Template type

Templates:

Template	Description
Unlit	Basic unlit shader
Standard	PBR surface shader
Transparent	Alpha blended

shader_read

Read shader source code.

Parameter	Type	Required	Description
shaderPath	string	Yes	Shader asset path

Returns: {success, path, content}

shader_list

Parameter	Type	Required	Default	Description
filter	string	No	null	Name filter
limit	int	No	100	Max results

Returns: {success, count, shaders: [{name, path}]}

shader_find

Find a shader by name.

Parameter	Type	Required	Description
shaderName	string	Yes	Shader name to find

Returns: {success, name, path, propertyCount}

shader_delete

Delete a shader file.

Parameter	Type	Required	Description
shaderPath	string	Yes	Shader asset path

shader_get_properties

Get all properties defined in a shader.

Parameter	Type	Required	Description

Returns: {success, properties: [{name, type, description}]}

shader_check_errors

Check shader for compilation errors.

Parameter	Type	Required	Default	Description
shaderNameOrPath	string	Yes	-	Shader name or asset path (e.g., "Custom/MyShader" or "Assets/Shaders/My.shader")

Returns: { shaderName, hasErrors, messageCount }

shader_get_keywords

Get shader keyword list.

Parameter	Type	Required	Default	Description
shaderNameOrPath	string	Yes	-	Shader name or asset path (e.g., "Custom/MyShader" or "Assets/Shaders/My.shader")

Returns: { shaderName, keywordCount, keywords: [{ name, type }] }

shader_get_variant_count

Get shader variant count for performance analysis.

Parameter	Type	Required	Default	Description
shaderNameOrPath	string	Yes	-	Shader name or asset path (e.g., "Custom/MyShader" or "Assets/Shaders/My.shader")

Returns: { shaderName, subshaderCount, totalPasses }

shader_create_urp

Create a URP shader from template (type: Unlit or Lit).

Parameter	Type	Required	Default	Description
shaderName	string	Yes	-	Shader name (e.g., "Custom/MyURPShader")
savePath	string	Yes	-	Save path (e.g., "Assets/Shaders/MyURP.shader")
type	string	No	"Unlit"	Template type: "Unlit" or "Lit"

Returns: { success, shaderName, path, type }

shader_set_global_keyword

Enable or disable a global shader keyword.

Parameter	Type	Required	Default	Description
keyword	string	Yes	-	Global shader keyword name
enabled	bool	Yes	-	true to enable, false to disable

Returns: { success, keyword, enabled }

Example Usage

import unity_skills

# Create an unlit shader
unity_skills.call_skill("shader_create",
    shaderName="Custom/MyUnlit",
    savePath="Assets/Shaders/MyUnlit.shader",
    template="Unlit"
)

# Create a surface shader
unity_skills.call_skill("shader_create",
    shaderName="Custom/MyPBR",
    savePath="Assets/Shaders/MyPBR.shader",
    template="Standard"
)

# Read shader source
source = unity_skills.call_skill("shader_read",
    shaderPath="Assets/Shaders/MyUnlit.shader"
)
print(source['content'])

# List all custom shaders
shaders = unity_skills.call_skill("shader_list", filter="Custom")
for shader in shaders['shaders']:
    print(f"{shader['name']}: {shader['path']}")

Best Practices

1. Use consistent shader naming (Category/Name)
2. Organize shaders in dedicated folder
3. Start with templates, modify as needed
4. Test shaders in different lighting conditions
5. Consider mobile compatibility for builds
