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

Annotations only declare the generic non-read-only, open-world, non-idempotent, non-destructive profile; the description adds genuinely new context — API key requirement, plugin must be in Live mode, insertion as textured MeshParts saved with the place, and a few-second latency. It omits what happens when the plugin is absent or whether the queued task is retried, which is the main remaining gap for a queue-based side-effecting 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?

Four short sentences, front-loaded with the action and outcome, then the required identifier and prerequisites. No filler sentences; every clause carries usable information.

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?

No output schema exists, and the description still conveys the observable effect, timing, and prerequisites, which is enough for an agent to invoke it confidently. It could say what the call returns (e.g. a queued job confirmation) and how to detect failure, but nothing essential to invocation is 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 description coverage is 100%, so the baseline is 3. The description reinforces taskId's source (list_3d_models) but says nothing about taskType (model vs image), so it adds little beyond 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?

States a specific verb and resource ('Queue one of your Waspes 3D models to appear in your open Roblox Studio place') with an explicit scope and outcome. It is clearly distinguishable from siblings like list_3d_models and connect_roblox, which are referenced rather than described as alternatives.

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?

Gives clear entry conditions: get the taskId from list_3d_models, hold a Waspes API key, and have the Studio plugin running in Live mode. It doesn't state any when-not-to-use case or what to do if the preconditions fail, so it falls short of a 5.

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