subdivide_mesh

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

Specifies the effect (subdivision with cuts per edge) and parameter range (1-100) but does not disclose if modification is in-place, destructive, or requires user selection. No annotations are provided.

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?

Very concise yet informative: includes purpose, parameters, and return type in a few sentences. No wasted words.

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 an output schema exists (true), the description only mentions a 'Confirmation dict' which is sufficient. However, it lacks details about state changes or side effects.

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?

Adds value beyond the schema by describing 'cuts' as 'Number of cuts per edge' and stating the allowed range (1-100). The schema itself has 0% description coverage, so the description compensates well.

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 tool's function: 'Subdivide a mesh.' This distinguishes it from siblings like 'subdivide_curve' and other mesh operations.

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. Does not mention prerequisites, when not to use, or compare with related operations like 'bevel_edges' or 'loop_cut'.

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