u1_inspect_model

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

No annotations are provided, so the description carries the behavioral disclosure burden. 'Inspect' implies a read-only operation on STL/3MF data, but the description does not disclose failure modes, required model source, output characteristics, or what exactly 'basic U1 fit information' includes.

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 a single, tightly written sentence with no filler. The key resource and purpose are front-loaded, and every word contributes meaning.

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?

With no annotations, no output schema, and an undocumented parameter, the description is not complete enough for reliable invocation. An agent still lacks critical context: how to provide `model`, what the return shape is, and how results relate to sibling tools.

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 0%, and the description does not clarify what the `model` parameter should contain (e.g., a file path, model ID, or reference returned from u1_list_models). The 'STL/3MF' hint weakly implies it is a 3D model, but the parameter semantics remain ambiguous.

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 verb ('Inspect'), a specific resource ('STL/3MF dimensions'), and a distinctive scope ('basic U1 fit information'). It is clear on its face, though it does not explicitly distinguish itself from sibling tools like u1_diagnose_model or u1_mesh_printability.

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?

There is no explicit when-to-use guidance, prerequisites, or mention of alternatives. The description only implies that the tool should be used when inspecting dimensions/fit, but an agent is not told when to prefer this over related inspection tools.

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