set_texture

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

No annotations are provided, so the description carries full burden. It only states 'Returns a message indicating success or failure', but does not disclose side effects (e.g., whether existing textures are replaced), error behaviors, or permission requirements. This is insufficient for a mutation tool.

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 with three short sentences. It front-loads the purpose and uses a clear list format for parameters. Every sentence adds value without 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?

For a simple tool with no output schema, the description covers the core action and prerequisite. However, it lacks details on error handling, success/failure conditions, and what happens to the object's material. Given the tool's limited complexity, it is minimally adequate but not thorough.

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 the two required parameters (object_name and texture_id) beyond their names in the schema. However, the optional user_prompt parameter is not described, and schema description coverage is 0%. The description partially compensates but misses covering all parameters.

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 verb 'Apply' and the resource 'previously downloaded Polyhaven texture to an object', which distinguishes it from sibling tools like download_polyhaven_asset and search_polyhaven_assets.

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 implies the prerequisite that the texture must be downloaded first ('must be downloaded first'), but it does not explicitly state when to use this tool versus alternatives or when not to use it. It provides some guidance but lacks explicit exclusion or alternative tool references.

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