blender_ai_generate_texture

Transform text prompts into PBR texture sets (diffuse, roughness, normal, metallic) and apply them directly to Blender objects. Generate realistic materials from descriptions like 'worn red brick wall' for 3D models.

Instructions

Generate a PBR texture set (diffuse, roughness, normal, metallic) from a text prompt using SDXL and apply it to a Blender object

C2.9/5.0
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden of behavioral disclosure. It states that a PBR set is generated and applied, but it does not disclose whether execution is asynchronous, whether existing materials are overwritten, how object selection behaves when object_name is omitted, or what the response contains.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single focused sentence that packs the core action, output maps, model, and application target without filler. It is appropriately sized and front-loaded with the main purpose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given six parameters, no output schema, and a large sibling set including a _sync variant, the description is incomplete. It fails to clarify async behavior, required object_name semantics when auto_apply is true, and how the agent should observe or retrieve generation results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the parameters are already well documented. The description adds useful context about the output being a PBR map set, but it does not meaningfully clarify parameter behavior beyond what the schema already provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states a specific verb and resource: generating a PBR texture set from a text prompt and applying it to a Blender object. It distinguishes itself from texture_from_render and inpaint_texture by emphasizing text-prompt generation and SDXL, though it does not explicitly differentiate from the _sync sibling.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given about when to choose this tool over alternatives such as blender_ai_generate_texture_sync, blender_ai_inpaint_texture, or blender_ai_texture_from_render. The description implies a general use case but does not explain execution mode, prerequisites, or exclusions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
