apply_poly_v_grooves

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Preflight or cut' implies a two-phase write operation, but the description never explains that preflight is non-destructive while cutting writes to the model, that confirm_write gates the actual write, or that the operation targets exactly one body (body_count const 1). The write/destructive implications and the return behavior are left unstated.

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 single sentence is tight, front-loaded with the verb, and contains no filler. However, it leans toward under-specification rather than genuine conciseness, omitting essential information about the two-phase behavior and inputs. The structure is clean but at the expense of completeness.

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 complex tool with a nested profile/target schema, no annotations, and no output schema, the description is incomplete. It does not explain the execute/confirm_write write flow, what data the rotational blank contract requires, or what preflight vs. cut returns. An agent cannot reliably determine inputs or interpret results from this definition.

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 adds nothing about parameters. With a complex nested schema (profile with designation enum PH/PJ/PK/PL/PM, effective_diameter, groove_count; target rotational-blank contract; execute/confirm_write booleans; axial_center), the description should compensate but explains zero parameter semantics. An agent has no guidance on what profile or target values to supply.

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 clear verb-and-resource ('Preflight or cut exact rounded Poly-V grooves into one global-X rotational body'), specifying the target body type and axis. It distinguishes from sibling apply_v_belt_grooves (V-belt vs Poly-V) and, via the 'Preflight or cut' wording, hints at its difference from preview_poly_v_groove. However, the preview-vs-apply distinction is implied rather than explicitly named.

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 gives no explicit when-to-use guidance or alternative routing. 'Preflight or cut' hints at a preview/execute duality but never tells an agent when to set execute=true versus execute=false, when confirm_write is required, or that list_poly_v_profiles/resolve_poly_v_profile should be used first to select a designation. No prerequisites (e.g., document open, rotational blank present) are stated.

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