create_heatset_insert_boss

Create a hollow boss sized for a heat-set insert by specifying outer radius, height, and insert radius, ensuring a correct fit.

Behavior2/5

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only restates the creation intent. It does not disclose whether the boss is created in the active document, whether doc_name overrides that, whether the operation is synchronous or asynchronous (relevant given get_operation_status), or any side effects.

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

Conciseness5/5

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

The description is a single front-loaded sentence with no filler or repetition. Every word earns its place, and it is immediately scannable by an agent.

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?

Although an output schema exists and the parameter names are somewhat self-descriptive, the absence of annotations and 0% schema description coverage leave too much implicit. An agent does not know how the dimensions relate (e.g., outer_radius must exceed insert_radius) or how doc_name affects the target document.

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%, so the description must compensate for the five parameters, none of which have descriptions. The phrase 'sized for a heat-set insert' weakly clarifies insert_radius, but it does not explain outer_radius, height, name, or doc_name, leaving their exact meaning and units unspecified.

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 states a specific operation ('Create') and a concrete resource ('a hollow boss sized for a heat-set insert'), making the tool's purpose clear. The heat-set-insert qualifier differentiates it from sibling tools like create_screw_boss and create_cylinder, though the distinction is implied rather than explicit.

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?

Usage is implied by the description: use when creating a boss for a heat-set insert, as opposed to screw bosses or vent patterns. However, it does not explicitly state when not to use it, nor does it mention the active-document requirement or any prerequisites.

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