get_model_info

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

Despite no annotations, the description clearly implies a read-only operation by naming 'get metadata' and 'read-before-write'. It also states the return type and gives examples of content. No side effects are expected, and the description is transparent enough for an 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 extremely concise, comprising two short sentences and a returns clause. Every sentence adds value: the first states purpose, the second gives context and examples, and the returns line specifies type. No wasted words.

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 zero-parameter tool with an output schema, the description is complete. It explains the purpose, the type of information returned, and the intended use case. The output schema provides further structure, so the description need not detail every field.

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?

With zero parameters, the description does not need to add parameter meaning. The schema coverage is 100% vacuously, and the description adds value by explaining the return context. Baseline 4 is appropriate per guidelines.

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 clearly states it retrieves metadata for the active SolidWorks document, listing specific attributes (document type, configuration, feature count). It distinguishes itself from siblings like get_mass_properties or list_features by focusing on a compact summary useful for read-before-write flows.

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 indicates it is for read-before-write flows, providing clear context for when to use. However, it does not explicitly state when not to use or suggest alternatives, though the intended use is clear given the sibling list.

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