protogen__generate_cad_design

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

No annotations are present, so the description must fully disclose behavioral traits. It only states the high-level action ('Generate') without detailing side effects, idempotency, required permissions, or the nature of the 'contract' being created.

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 concise (one sentence plus prefix), but this brevity sacrifices critical information. It is front-loaded with the purpose, but lacks substance for a tool with 7 parameters.

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?

Despite the tool's complexity (7 parameters, nested objects, no output schema), the description is extremely incomplete. It does not address return values, parameter usage, or the concept of a 'CAD design contract', leaving the agent with minimal contextual guidance.

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 description does not explain any parameters. Given 0% schema description coverage, the description fails entirely to add meaning to the 7 parameters, including 3 required ones (workspace_id, part_name, dimensions_mm) and nested objects.

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 the action ('Generate'), resource ('parametric CAD design contract'), and context ('in a ProtoGen workspace'). It is specific enough to convey the primary purpose, but does not differentiate from sibling tools like protogen__export_cad_design or protogen__manufacturing_plan_from_spec.

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?

No usage guidelines are provided. The description does not indicate when to use this tool over alternatives, nor does it mention prerequisites or context for invocation.

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