rhino_unweld_mesh

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

Annotations already indicate this is a mutating operation via readOnlyHint=false, and the description only adds the effect 'break mesh smoothing'. It does not disclose whether all vertices are unwelded or only selected ones, whether smoothing/normals are permanently changed, or what the undo/destructive profile is.

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 a single, front-loaded sentence with no filler. It is compact and easy to scan, though the brevity comes at the cost of important operational detail.

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?

The output schema covers return shape, but the description lacks essential invocation context: how the target mesh is selected, whether the unweld applies to the entire mesh, and how this operation relates to welding or smoothing. An agent would likely need to inspect the schema and sibling tools to use this 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?

Schema description coverage is 0% and the description does not mention object_id, doc_id, name, or layer. The agent is given no help understanding that object_id is required to target the mesh or what the optional name/layer fields do. The schema titles provide only minimal, generic hints.

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 names the specific verb 'Unweld' and the resource 'vertices', and states the intended effect 'to break mesh smoothing'. This is clear enough to identify the operation and distinguish it from rhino_weld_mesh, though it does not explicitly reference any sibling.

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?

There is no guidance on when to use this tool versus alternatives such as rhino_weld_mesh, rhino_cmd_unweld_mesh, or other mesh-editing operations. The intended usage must be inferred entirely from the tool name and the single-sentence description.

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