set_texture

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

With no annotations, the description must handle behavioral disclosure. It mentions that a success/failure message is returned and that the texture must be downloaded first, but it does not disclose side effects like overwriting existing materials or error behavior if the texture is not found. This leaves important behavioral aspects unclear.

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

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

The description is concise and well-structured, starting with a clear purpose sentence followed by a compact parameter list. Every sentence adds value, and there is no filler or redundancy.

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

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

This is a mutation tool with no annotations or output schema, and the description does not fully compensate. It lacks details on error handling, effect on existing materials, and the meaning of the success message. The missing user_prompt documentation further reduces completeness.

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

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

The description adds meaning for object_name and texture_id, clarifying that texture_id must reference a previously downloaded asset. However, it omits the optional user_prompt parameter entirely, so not all parameters are explained. Given the 0% schema description coverage, the description partially compensates but has a gap.

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

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

The description clearly states the tool applies a previously downloaded Polyhaven texture to an object. The verb 'apply' and resource 'Polyhaven texture' are specific, and the tool is clearly distinguished from siblings like download_polyhaven_asset or execute_blender_code.

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

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

The description conveys a prerequisite (texture must be downloaded first) but does not explicitly state when to use this tool over alternatives or mention any exclusions. The usage context is implied but not fully elaborated.

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