DH Parameters to URDF

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

The description adds behavioral info beyond annotations by stating it handles standard and modified conventions correctly, which is critical for domain-specific usage. Annotations already indicate safety (readOnly, idempotent, non-destructive).

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 (one short sentence) and front-loaded with the core purpose. Every word is necessary.

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 domain-specific conversion tool, the description is minimal. It lacks details about output format, validation, error handling, and usage examples. With no output schema, more context would be beneficial.

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 add any meaning beyond the input schema. With 50% schema description coverage, the description fails to clarify parameters like robotName and convention, which have no schema descriptions.

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 tool's action ('Generate') and the specific resource ('URDF joint chain from a Denavit-Hartenberg table'), and distinguishes it from sibling tools by focusing on DH tables and convention handling.

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?

While the description implies usage when DH parameters are available, it does not explicitly state when not to use it or mention alternatives among siblings (e.g., sdf_to_urdf, step_to_urdf).

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