tris_to_quads

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

With no annotations, the description carries the transparency burden. It notes that not all triangles can be merged due to angle compatibility, which is useful. However, it does not disclose whether the operation modifies the mesh in-place, potential side effects, or if it returns the same object. This leaves gaps.

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 concise with a clear verb-first statement, a note on limitations, and structured args. It front-loads the action and avoids fluff, though the limitations sentence could be slightly more succinct.

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 the tool's simplicity (one param, no output schema details needed beyond confirmation dict), the description covers the operation, limitations, parameter, and return. However, it lacks examples or context relative to other topology tools, which would enhance completeness.

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 schema has 0% description coverage, but the tool description includes an explicit 'Args' section with a brief description for the single parameter 'object_name'. This adds meaning beyond the schema, though it could be more detailed about valid inputs.

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 converts adjacent triangle pairs to quad faces, specifying the mesh object as the resource. It differentiates from the sibling tool 'quads_to_tris' by focusing on the opposite operation, thus achieving high purpose clarity.

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 mentions improving topology for subdivision and deformation, hinting at use cases, but does not explicitly state when to use this tool versus alternatives like 'dissolve_faces' or 'quads_to_tris'. No when-not guidance or comparison to siblings is provided.

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