compare_with_mesh

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

Annotations already establish that this is a read-only, idempotent, non-destructive, closed-world operation. The description adds useful context that public geometry units are mm, degrees, and kg and that results include 'verified measurements and error evidence,' but it does not explain tolerances, failure behavior, or the comparison method.

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 brief and free of obvious filler, with the core comparison concept front-loaded. Its short sentences are easy to scan, though the middle units sentence is somewhat disconnected from the action.

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 five-parameter comparison tool with no output schema and no parameter descriptions, the definition is materially incomplete. It mentions units and error evidence but leaves input semantics, comparison behavior, and return structure unspecified.

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 explains none of the five parameters. It does not clarify what 'path' points to, how 'axis' is interpreted, what 'heights_mm' means, or how 'frame' and 'offset_mm' affect the comparison.

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 largely restates the tool name: 'Compare with mesh.' It adds mechanism ('independent native SOLIDWORKS engine') and units, but never states what is being compared to the mesh or what a comparison produces, leaving the core purpose ambiguous.

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, when to prefer siblings such as pro_inspect_stl, pro_verify_volume, or check_interference, or any prerequisites for the input mesh. Usage must be inferred entirely from the name.

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