create_category

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

No annotations exist, so description carries full burden. It discloses case-insensitive duplicate rejection and a max limit of 100 categories, which are key behavioral traits. Could mention success response or error handling.

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?

Two concise sentences plus a simple parameter line. Every word adds value, and the most important info (purpose, duplicate behavior, limit) is front-loaded.

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 single-parameter create tool with no output schema, the description covers core aspects: what it does, conflict handling, and capacity. Minor gaps like response structure but adequate for the complexity.

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 description briefly explains the 'name' parameter as 'Category name to add', adding minimal meaning beyond the schema. With 0% schema coverage, this compensates slightly but lacks details like length constraints.

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 it adds a custom category. The tool name itself distinguishes it from siblings like delete_category, but the description does not explicitly differentiate.

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?

Mentions duplicate rejection and max limit, providing some context for usage. Does not explicitly state when not to use or suggest alternatives like checking existing categories first.

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