create_category

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. It mentions the fields and parentCategoryId semantics, but does not disclose permissions, validation rules, idempotency, or the return value of the creation. For a write operation, this is a significant gap.

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 sentence with a short list of fields, front-loaded with the action. It is concise and every word provides value, with no fluff or repetition.

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 tool has one nested parameter, no output schema, and no annotations, the description provides useful field guidance and a hint to inspect an existing record. However, it omits return value and error handling details, leaving some ambiguity for an agent invoking the tool.

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?

The input schema already describes the single 'data' parameter with the same common fields, achieving 100% coverage. The description adds a useful pointer to get_category for the full record shape, slightly beyond the schema, but this is minimal. The baseline of 3 is appropriate.

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 opens with 'Create a new category,' which is a specific verb and resource, clearly distinguishing it from sibling tools like update_category and delete_category. It immediately captures the core action.

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 lists common fields and advises calling get_category to see the full shape, giving useful context for how to construct the data object. It doesn't explicitly state when not to use this tool, but the context is clear enough for an agent to differentiate it from update/delete operations.

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