Create a skill category

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

Annotations already provide the readOnly, idempotent, and destructive safety profile. The description adds useful behavioral context: the operation is scoped to the current business and category names must be unique within that business. It does not contradict any annotation, though it does not describe duplicate-name failure behavior.

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 mostly tight and front-loaded, with the real definition in the first sentence and useful examples and constraints afterward. It loses one point because the opening line 'Create a skill category' simply repeats the title before the substantive description begins.

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 simple create operation with three fully documented parameters and annotations covering the safety profile, the description is complete enough to select and invoke correctly. The schema covers the required name and the optional icon and idempotency_key, while the description supplies business scope and uniqueness context.

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 100%, so the baseline is 3. The description adds value beyond the schema by clarifying that name is a business-scoped unique category label and by explaining the category-skill grouping relationship. It does not discuss icon or idempotency_key, but those are already fully described in the schema.

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 clearly states a specific action and resource: 'Creates a skill category for the current business.' It also distinguishes this from the sibling createSkill by explaining that categories group skills, and it gives concrete trade examples. The uniqueness constraint further clarifies the tool's exact domain.

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 intended use is implied rather than explicit: an agent can infer to use this when creating a category, not a skill, because 'Categories group skills.' However, the description does not name alternatives like createSkill, say when not to use it, or advise checking existing categories before using it despite the uniqueness requirement.

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