rhino_create_uv_grid

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

With no annotations beyond title, the description bears full burden for behavioral disclosure. It states the tool creates a point grid, implying object creation, but provides no details on side effects, data modification, or error conditions.

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?

Extremely concise (11 words, one sentence). Information is front-loaded but lacks structure. Could benefit from expanding parameter details while staying efficient.

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?

Given no annotations, high parameter count (4), and an output schema (not shown), the description is insufficient. It does not describe return values, preconditions, or errors, leaving the agent uninformed.

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 coverage is 0% with two parameters (u_count, v_count) undocumented in schema. The description hints at their meaning via 'even UV intervals', but fails to explain 'object_id' (GUID of surface) or 'layer'. Minimal added value over the schema.

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 verb 'Create' and the resource 'point grid on a surface', with the method 'at even UV intervals'. While specific, it does not explicitly distinguish from sibling tools like 'rhino_place_grid' or 'rhino_uv_grid_panels', but purpose is unambiguous.

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?

No guidance on when to use this tool versus alternatives. It does not mention prerequisites (e.g., a surface must be selected) or when not to use it. The description lacks any usage context.

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