preview_poly_v_groove

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

No annotations are provided, so the description carries the full burden. It discloses that the preview excludes hubs, bores, and COM, which is useful, but it does not state whether the operation is read-only, what the output looks like, or any side effects. For a preview tool, the lack of behavioral clarity is a significant gap.

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 a single sentence with no filler. It front-loads the verb and resource, then adds the key exclusions. Every word earns its place, and it is appropriately sized for the tool.

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?

There is no output schema, no annotations, and the description is minimal. Given the domain complexity (poly-V pulleys) and the large set of sibling tools, the description does not provide enough context about return values, safety, or how it fits into the broader workflow. An agent would struggle to know what to expect from calling this tool.

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%, meaning the description does not explain any parameters. The schema itself has clear field names and an enum for designation, but the description adds no semantic meaning beyond what the field names imply, such as units for effective_diameter or the purpose of groove_count.

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 ('Preview') and a precise resource ('rounded Poly-V pulley groove set') and explicitly lists exclusions (hubs, bores, COM). This clearly distinguishes it from apply tools (apply_poly_v_grooves) and other preview tools like preview_v_belt_groove, leaving no ambiguity about the tool's scope.

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 implies the tool is for previewing poly-V grooves, but it does not explicitly state when to use this versus alternatives like preview_v_belt_groove or apply_poly_v_grooves. There is no mention of conditions, prerequisites, or why one would choose this tool over others.

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