Add members

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

No annotations provided, so description carries burden. It explains beam vs truss (6 DOF vs axial) and rollDeg rotation, but doesn't disclose error behavior (e.g., if nodes don't exist) or side effects. Partially adequate.

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?

Two concise sentences with no redundancy. First sentence defines purpose, second adds key details on type and rotation. Efficient and well-structured.

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?

With no annotations or output schema, the description should cover more. It lacks explanation of how to specify node indices ('from', 'to'), section and material references, and array structure. Incomplete for a complex parametric tool.

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?

Schema description coverage is 0%, so description must compensate. It explains 'type' and 'rollDeg', but fails to clarify critical parameters like 'from', 'to', 'section', 'material', and the structure of the 'members' array. Only partial coverage.

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?

Description clearly states the verb 'Add', resource 'beam or truss members', and context 'between existing nodes'. It distinguishes from sibling tools like add_nodes and add_loads by specifying the action and resource.

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?

Implicitly indicates that nodes must exist before adding members. No explicit when-not or alternative tool references, but the context is clear enough for an agent to understand basic usage.

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