Generate CAD model

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

Annotations indicate the tool is not read-only, but the description does not clarify whether the generated model is persisted to the workspace, whether it creates a new model entity, or what side effects occur besides generation. With readOnlyHint=false, the write nature is implied, but the description adds no concrete behavioral detail beyond the verb 'generate', leaving side effects underspecified.

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, concise sentence that front-loads the action and outcome. It includes the essential list of templates without unnecessary detail. The word 'useful' is slightly subjective but does not materially add bloat; the structure is optimal for a tool description of this simplicity.

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?

Given the presence of a nested parameters object, multiple template options, and no output schema, the description is incomplete. It does not explain how to choose templates, how to provide parameters, or what the return value looks like. For an agent to use this tool correctly, it would need additional clues from the schema or examples, which are absent.

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 description coverage is 0%, and the description adds no meaning to the parameters. It does not explain what 'parameters' means, which parameter applies to which template, or how 'name' and 'color' are used. The template enum is merely repeated, not enriched. The nested 'parameters' object has seven properties with no guidance, making this parameter semantics entirely inadequate.

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 action ('Generate'), a specific output ('CAD model'), and a clear scope ('from a built-in template') while listing the available template types (bracket, pipe, gear, enclosure, or bolt). This distinguishes it from sibling tools like create_model, load_model, and import_model by emphasizing a template-driven generation workflow.

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 phrase 'from a built-in template' implies the tool is intended for generating models from predefined templates rather than arbitrary or imported geometry. However, it does not explicitly state when not to use this tool or mention alternatives such as create_model, load_model, or import_model, so the usage guidance remains implied rather than explicit.

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