rhino_quadrangulate_mesh

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

With no annotations, the description carries the full burden of explaining behavior. It notes 'where possible,' which signals best-effort behavior, but it does not disclose whether selected meshes are modified in place, whether unselected meshes are affected, whether a new object is created, or what happens when no meshes are selected.

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 core sentence is appropriately short and front-loaded, but the second 'Args:' line is redundant and contradictory to the empty schema. Not every sentence earns its place; the extra line actively harms clarity by referencing a non-existent parameter.

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 mesh-editing tool with no annotations and no input schema, the description should disclose whether the operation is destructive, whether it requires a prior selection, and what the result will be. The output schema may cover return values, but the absence of selection and mutation semantics leaves an agent uncertain about how to invoke the tool correctly.

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 input schema has zero parameters, which is the baseline for a high score, but the description's 'Args: controller: RhinoController instance' introduces a parameter that does not exist in the schema. This creates inconsistency and could mislead an agent into expecting a controller argument. The description therefore adds confusion instead of meaningful parameter meaning.

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 explicitly states a specific action ('Convert triangular faces in selected meshes to quads') and the resource ('selected meshes'). It distinguishes itself from nearby siblings like rhino_triangulate_mesh and rhino_quad_remesh by clearly defining its operation and scope.

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?

The description gives no guidance on when to use this tool versus alternatives such as rhino_quad_remesh or rhino_reduce_mesh. It implies the tool acts on selected meshes, but there are no explicit conditions, prerequisites, or exclusions stated.

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