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

Beyond the annotations, the description discloses that the call queues work asynchronously, inserts the model as textured MeshParts in Live mode, saves it with the place, and completes within a few seconds. It also names the required API key and running plugin, which are important operational prerequisites not captured by the annotations.

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 four front-loaded sentences with no wasted wording. It moves from action to parameter source to runtime behavior to prerequisites in a logical order.

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 two-parameter mutation tool with a fully covered schema and no output schema, the description supplies the important runtime context: Live mode, plugin availability, API key requirement, insertion format, persistence, and timing. Nothing critical for correct invocation appears to be missing.

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 already 100%, so the baseline is 3. The description adds useful meaning by explaining that taskId comes from list_3d_models and that both Tripo 't.' ids and legacy Meshy ids are accepted; taskType is left to 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 states a specific action ('Queue ... to appear'), a specific resource (a Waspes 3D model), and a specific destination (an open Roblox Studio place). It also distinguishes the source of the required taskId by naming list_3d_models, so the agent can identify this as the send/insert step rather than the listing step.

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 gives clear usage context: pass a taskId from list_3d_models, have the Waspes Studio plugin in Live mode, and provide a Waspes API key. It does not explicitly compare this tool with alternatives such as connect_roblox or state when not to use it, which keeps it from a 5.

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