measure_centroid

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

No annotations are provided, so the description carries the full behavioral burden. It implies a read-only measurement via the verb 'measure', but does not disclose return format, side effects, permissions, or whether the operation is computationally expensive.

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 terse sentence with no wasted words, but it is under-specified for a tool with two parameters. It is front-loaded but too short to provide necessary context, making it more of a stub than a useful definition.

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?

Given the absence of annotations, output schema, and schema parameter descriptions, the description is inadequate. It does not explain parameters, return values, or behavioral traits, leaving the agent unable to call the tool correctly without guessing.

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 no parameter information. The required solid_id and optional axis array are completely undocumented; an agent must guess how to specify the solid and what the axis array represents (e.g., direction vector or measurement axis).

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?

States a specific verb 'measure' and resource 'solid centroid', so the basic operation is clear. However, it does not distinguish this tool from sibling measurement tools (e.g., get_mass_properties, measure_volume) that might also report centroid, leaving ambiguity about when to choose this one.

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?

Provides no when-to-use guidance, prerequisites, or alternatives. An agent cannot tell from the description whether this requires a selected solid, a loaded document, or specific preconditions.

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