Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint, idempotentHint, non-destructive behavior, and closed-world scope. The description usefully adds that the call is free and does not trigger model calls, which is meaningful cost and side-effect context beyond the annotations. It does not describe the response shape, but the annotations carry the safety profile.
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 compact sentences with the key differentiator, "Free", front-loaded, followed by the discovery scope and the "No model calls" constraint. Every phrase contributes useful information and there is no filler.
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 parameterless, read-only informational tool with no output schema, the description gives enough detail about what will be discovered: capabilities, formats, pricing, and purchase URL. It also discloses the important behavioral constraint that no model calls are made.
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 tool has zero parameters, so there is no parameter semantics burden. The schema coverage is 100% and the description appropriately does not add parameter details. A baseline score of 4 is appropriate for a parameterless discovery tool.
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 uses a specific verb, "Discover", and lists the exact information returned: MBEstudio capabilities, enabled formats, pricing, and purchase URL. It clearly distinguishes this informational endpoint from operational siblings like build_3d_model and mbe_commit, though it does not explicitly name an alternative tool.
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 implies this is a discovery/information tool, and the phrases "Free" and "No model calls" help signal low-cost, safe usage. However, it does not explicitly say when to use this instead of the many mbe_* or build_* tools, nor does it state prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
