set_texture

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

Since no annotations are provided, the description carries the full burden of disclosing behavior. It states the core operation but gives no information about side effects (e.g., replacing existing materials), reversibility, permissions, or failure modes. For a mutation tool, this is a significant gap.

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 a single concise sentence that places the action and target up front. There is no wasted wording, and it fully fits a tool with only two parameters.

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 description covers the core operation and the schema documents both parameters, but important context is missing: the need for a previously downloaded texture, whether the object must already exist, and what happens to existing materials. This leaves the definition adequate but with clear gaps.

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?

Schema description coverage is 100%, with both texture_id and object_name described in the schema. The tool description adds little beyond that, merely restating the texture/object concepts, so it does not improve on the baseline provided by the schema.

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 names a specific verb ('Apply'), a specific resource ('a downloaded PolyHaven texture'), and a target ('to an object'). This clearly distinguishes it from sibling tools like download_polyhaven_asset or search_polyhaven_assets, which handle other stages of the texture workflow.

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 offers no explicit when-to-use guidance, exclusions, or alternatives. The word 'downloaded' implies a prerequisite step, but it does not clearly instruct the agent to download the texture first or to ensure the target object exists, and no sibling tool is named as an alternative.

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