Gear: Spur Front View

gear_draw_spur_front_view

Draws a deterministic spur gear front view based on module, teeth count, and optional bore, keyway, and pressure angle parameters.

Instructions

Deterministic spur gear front view (no helix symbol).

Behavior3/5

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

Annotations only provide destructiveHint: false, so the description carries most of the burden. It adds 'Deterministic' (repeatable output) and 'no helix symbol' as behavioral traits beyond the annotations, but discloses nothing about whether geometry is created in the drawing or how the output behaves.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, front-loaded sentence with no filler; the key differentiator is placed compactly. It is appropriately short, though borderline under-specified as a noun phrase rather than an actionable statement.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 8 parameters, a drawing-creating tool, and minimal annotations, the description is too thin: no guidance on geometry placement, units, or what gets inserted into the drawing. The output schema covers return values, but the agent is left to infer most behavioral context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description provides no information about any of the 8 parameters (module, teeth, center_x, keyway, bore, pressure_angle). Parameter names are self-explanatory, but the description fails to compensate for the total lack of schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies the resource (spur gear front view) and a distinguishing trait (no helix symbol), which separates it from gear_draw_helical_front_view. However, it lacks an explicit verb like 'draws/creates', leaving the action implied by the tool name.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The parenthetical '(no helix symbol)' implies that helical gears with a helix symbol belong to gear_draw_helical_front_view, but no alternative is named explicitly and no when-to-use/when-not-to guidance is given.

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