loop_cut

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

With no annotations, the description carries the full burden of behavioral disclosure. It vaguely mentions 'best effort' and 'may need viewport context', hinting at possible failure or environmental dependencies, but it does not describe the effect on the mesh, reversibility, or side effects. This is minimal but non-zero transparency.

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 text is extremely brief, but it is under-specification rather than effective conciseness. It lacks any structured breakdown or essential operational detail. The few words used do not earn their place because they add minimal practical value.

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 operation with two parameters and no annotation coverage, this description is critically incomplete. The agent cannot determine how to invoke the tool, what inputs mean, or what outcome to expect. The existence of an output schema does not compensate for the missing behavioral and semantic context.

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 explain the parameters 'edge_index' or 'number_cuts'. Nothing indicates their types, meanings, or how they affect the operation. The agent has no help in filling these fields correctly.

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 'Loop cut' essentially restates the tool name without explaining what the operation does. The added note about 'best effort' and 'viewport context' provides no clarity on the tool's purpose or how it differs from mesh-editing siblings like 'subdivide' or 'bevel'.

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 is given on when to use this tool versus alternatives such as 'subdivide' or 'extrude_region'. There is no mention of prerequisites, context, or conditions under which it should be chosen.

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