set_texture

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

With no annotations provided, the description carries the full burden. It notes that the tool returns a success/failure message but does not specify error conditions (e.g., missing object, invalid texture ID) or side effects. Some context is given via parameter descriptions.

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 very concise—one sentence for the main action, two bullet points for parameters, and one sentence for return value. No wasted words, and the most important information (what it does) is front-loaded.

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's simplicity and the presence of an output schema (as indicated in context signals), the description is mostly complete. It covers the action, required parameters, and return type. Minor gaps remain around error handling and prerequisites beyond 'downloaded,' but it's sufficient for a straightforward apply operation.

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 fully explains both parameters: object_name as 'Name of the object to apply the texture to' and texture_id as 'ID of the Polyhaven texture to apply (must be downloaded first).' This adds significant meaning beyond the schema's type-only definitions.

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), the resource (Polyhaven texture), and the target (object). It effectively distinguishes this tool from siblings like download_polyhaven_asset or 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 mentions the texture must be 'previously downloaded,' implicitly guiding usage after download_polyhaven_asset. However, it does not explicitly state when not to use or list alternatives.

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