C2.6/5.0

Behavior2/5

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

No annotations are provided, so the description carries full burden. It states 'generate' implying a creation action but does not disclose side effects, idempotency, required workspace existence, or any constraints. The description is insufficient for an agent to understand behavioral traits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but lacks structure. It could be organized into brief sections for purpose, parameters, and behavior. While it is short, it sacrifices completeness for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool complexity (8 parameters, nested objects, no output schema, no annotations), the description is far from complete. It does not explain the return value, the meaning of 'contract', or the role of optional parameters. The agent would need additional context to use the tool correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, meaning the description must compensate by explaining parameter meanings. The description only mentions 'parametric CAD design' and 'dimensions' but does not clarify any of the 8 parameters such as 'features', 'design_intent', or 'output_formats'. This fails to add value beyond the schema's property names.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Generate' and the resource 'parametric CAD design contract in a ProtoGen workspace.' It distinguishes from sibling tools like protogen__export_cad_design and protogen__create_cad_workspace. However, the term 'parametric CAD design contract' is ambiguous and could be more specific.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool vs. alternatives, e.g., when to use protogen__export_cad_design instead. No prerequisites or context signals are mentioned.

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