export_configuration_cad

Export a full aircraft configuration or a single component to STEP/IGES and return the file path for mesh generation; optionally include Base64 content when needed.

Instructions

Export the full configuration CAD (or a single component when component_uid is set) to a file and return its path as cad_path. Pass cad_path to su2_generate_mesh_from_step as step_path. Set include_base64 only if the file content itself is needed.

A3.7/5.0
Behavior3/5

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

With no annotations, the description carries the full burden; it does disclose that a file is written and that the path is returned as cad_path, which is useful mutation context. It omits overwrite behavior for output_path, permission/session requirements, format defaults, and any size/pagination concerns.

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

Conciseness5/5

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

Three tight sentences, front-loaded with the action and scope, then upstream/downstream linking, then the optional flag. No filler.

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

Completeness3/5

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

It covers the return value well (cad_path) despite no output schema, and links to the downstream tool. But for a 5-parameter file-writing tool with zero schema documentation, the unexplained output_path and session_id leave real gaps.

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

Parameters3/5

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

Schema description coverage is 0% across 5 parameters, so the description must compensate. It explains component_uid and include_base64 meaningfully, but leaves output_path (where the file lands, overwrite semantics) and session_id unexplained, and only the enum values hint at format.

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?

States a specific verb and resource (export configuration CAD) and clarifies scope: full configuration vs. a single component when component_uid is set. It does not, however, distinguish itself from the sibling export_component_mesh, which an agent could plausibly confuse with this tool.

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

Usage Guidelines4/5

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

Gives concrete downstream wiring — pass cad_path to su2_generate_mesh_from_step as step_path — and a conditional rule for include_base64 (only when file content itself is needed). No explicit when-not or sibling alternative is offered, but the intended workflow is clear.

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