set_texture

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

With no annotations, the description carries the burden of disclosure. It mentions the return message and the download prerequisite, but it doesn't disclose side effects like whether existing object materials are overwritten or what happens if the object doesn't exist. This is adequate but not rich.

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 compact: a single purpose sentence, a minimal parameter list, and a return-value statement. No unnecessary words 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?

The tool is simple, but the description doesn't fully complete the picture: user_prompt is undocumented, and there is no mention of error behavior or effect on existing object textures. The return value is mentioned, so it's not wholly incomplete.

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 schema has 0% description coverage, so the description must compensate. It explains object_name and texture_id clearly, including the constraint that texture_id must be downloaded first. However, the schema's user_prompt parameter is completely omitted from the description, leaving its purpose unexplained.

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 uses a specific verb 'Apply' with a clear resource ('previously downloaded Polyhaven texture') and target ('object'). It effectively distinguishes the tool from siblings like download_polyhaven_asset and search_polyhaven_assets by focusing on the application step.

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 clearly states the prerequisite that the texture must be downloaded first, providing context for when the tool is appropriate. It doesn't explicitly mention alternatives or when not to use it, but no close alternative exists among the sibling tools.

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