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 mentions the tool applies textures and returns success/failure messages, but lacks details on behavioral traits like required permissions, whether it modifies existing textures, error conditions, or side effects. For a mutation tool with zero annotation coverage, this is insufficient.

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 front-loaded with the core purpose, followed by a structured parameter list and return statement. Every sentence earns its place with no wasted words, making it highly efficient and easy to parse.

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?

Given the tool has 2 parameters, no annotations, no output schema, and operates in a complex 3D modeling context, the description is minimally adequate. It covers purpose and parameters but lacks details on behavioral aspects, error handling, or integration with sibling tools, leaving gaps for an AI agent.

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 0%, so the description must compensate. It adds meaningful semantics for both parameters: object_name specifies the target object, and texture_id clarifies it's a Polyhaven texture ID with a prerequisite ('must be downloaded first'). This goes beyond the bare schema, though it doesn't detail format constraints like ID structure.

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 specific action ('Apply a previously downloaded Polyhaven texture') and target resource ('to an object'), distinguishing it from sibling tools like download_polyhaven_asset (which downloads) or get_object_info (which inspects). It precisely defines the tool's function with verb+resource+constraint.

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 provides clear context for when to use this tool ('Apply a previously downloaded Polyhaven texture') and implicitly indicates prerequisites (texture must be downloaded first). However, it doesn't explicitly state when NOT to use it or name alternatives among siblings, such as whether other texture-application tools exist.

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