plasticity_create_hinge_barrel

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

Annotations already declare destructiveHint=true and readOnlyHint=false, and the description adds worthwhile context: the recipe uses four native history steps and returns every confirmed revision. However, it never states what geometry is destroyed or how the join affects the target Solid, leaving a gap against the destructive annotation.

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?

Three sentences, front-loaded with the operation, with no filler. The sizing/seam details are reasonably placed but the third sentence is somewhat clipped.

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 9-parameter composite CAD operation with 0% schema coverage, no output schema, and a destructive annotation, the description leaves several required parameters (revision, outerDiameterMm, lengthMm, intent) and the cutterOvershoot default unexplained.

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%, so the description carries the full burden. It clarifies that the axis is world-space and that the bore is the finished pin-clearance diameter, but lengthMm, outerDiameterMm, cutterOvershootMm, revision, and intent go entirely undocumented.

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 states a specific verb (Create), a specific resource (hollow cylindrical hinge barrel), and scope (along a world-space axis, joined to one existing Solid). This distinguishes it from generic siblings like plasticity_create_cylinder without opening either schema.

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?

It establishes context that the barrel is joined to exactly one existing Solid, implying when the tool applies, but never states when to prefer it over alternatives such as create_cylinder or boolean. Usage is implied rather than spelled out.

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