set_texture

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

No annotations are provided, so the description carries the full burden. It does not disclose what happens if the texture ID is invalid, whether existing textures are replaced, or the exact effect on the object's material. The return message is vaguely described.

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 with a short summary followed by parameter descriptions. It is not verbose and each sentence contributes useful information.

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 tool with two parameters and no output schema, the description is moderately complete. It covers the basic purpose but lacks behavioral details such as error handling, side effects, or return value structure. Given the tool's simplicity, it is adequate but not comprehensive.

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 basic semantics beyond the schema by explaining the purpose of each parameter (name, ID). However, it lacks details on format, constraints, or dependencies between parameters, and schema coverage is 0%.

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 action (apply) and the resource (Polyhaven texture to an object), and implies a prerequisite (previously downloaded). It distinguishes from siblings like assign_material or load_texture, though it could be more explicit about what 'apply' means.

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 mentions a prerequisite ('must be downloaded first') but does not provide guidance on when to use this tool versus alternatives like assign_material or load_texture, nor does it explain when not to use it.

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