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 the basic operation and a prerequisite, but does not disclose what happens to the object's material (e.g., replacement, slot assignment), required material existence, or any side effects. This is insufficient for safe use.

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 two sentences long, front-loads the action, and contains no extraneous information. Every word is relevant and purposeful.

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?

Despite the tool's low complexity, the description omits crucial details: whether the object must have a material, whether the texture replaces or adds, error conditions, and behavior if the texture_id is invalid. The prerequisite is the only additional context beyond the action.

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 coverage is 0%, yet the description adds no meaningful explanation for either parameter. 'texture_id' is only mentioned as prerequisite, not its format or how to obtain it. 'object_name' has no description. The parameter semantics are completely lacking.

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 a previously downloaded PolyHaven texture to an object.' It uses a specific verb and resource, and the prerequisite distinguishes it from generic material tools like 'set_material' or 'material_set_texture'.

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 explicitly states the prerequisite: 'texture_id must have been downloaded first via download_polyhaven_asset.' This gives clear context for when to use the tool, though it does not compare directly to sibling tools or state 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.
