get_sketchfab_status

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

The description says the tool performs a check and returns a message, which implies a non-mutating status probe. However, there are no annotations, so the description carries the full transparency burden; it does not explicitly state that there are no side effects, no authentication requirements, or no network modifications. This is a moderate gap for such a simple status tool.

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 short, declarative sentences. It front-loads the primary action and immediately states the result, with no filler, repetition, or unnecessary detail. Every sentence contributes value.

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 simple no-required-parameter status check with an output schema present, the description is nearly complete: an agent can call it and understand the general response. The missing note about the optional user_prompt parameter and the lack of sibling routing guidance prevent a perfect score, but the omission is not critical for basic invocation.

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 schema has one optional parameter, user_prompt, with zero schema description coverage and no parameter documentation. The tool description never mentions this parameter or explains whether/how it affects the returned status. Although the parameter is optional with a default, the agent receives no guidance about whether to supply it or what it controls.

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 opens with a specific verb and resource: 'Check if Sketchfab integration is enabled in Blender.' It then clarifies the output (a message indicating availability), making the tool's purpose unambiguous and distinct from sibling status tools for other services.

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 directly states when this tool is relevant: when you need to determine whether Sketchfab features are available in Blender. It does not explicitly mention sibling alternatives or exclusions, so it stops short of a 5, but the usage context is clear and not merely hidden in the name.

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