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

No annotations are provided, so the description must disclose behavior. It states the operation is a fetch (implying read-only) and requires API credentials, which is useful. However, it does not elaborate on side effects, rate limits, or error behavior, leaving some burden on the agent.

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 exceptionally concise: one sentence with a clear verb, resource details, and a credential prerequisite. The parenthetical list of result contents adds value without excess length.

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 single-parameter tool with no output schema, the description sufficiently covers the purpose, input, and credential requirement. It could mention the exact return format, but the tool's low complexity makes this adequate.

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 already fully describes the single parameter (file_access_id with its source), yielding 100% schema coverage. The description reinforces the purpose by mentioning 'by its fileAccessId' but adds no new format or constraint details 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?

The description uses a specific verb ('fetch') and identifies the resource ('analysis result' with dimensions/volume/printability) for an uploaded model, clearly distinguishing it from sibling tools like pricing or order management. The 'Official 3D-printing API' prefix adds context without ambiguity.

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 usage after uploading a model by referring to fileAccessId from a prior upload and mentioning API credentials as a prerequisite. It does not explicitly name alternatives or exclusions, but the context is clear enough for a straightforward fetch operation.

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