create_category

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states it creates a category, lacking information about side effects, permissions, idempotency, or error behavior (e.g., duplicate handling). The agent is left unaware of critical behavioral traits.

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?

Extremely concise with two sentences and a brief Args list. The primary action is stated first, with no unnecessary words. Every sentence adds value.

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 simple parameters and no output schema, the description covers the creation action and parameter meanings but omits return value or error handling. It is adequate but not fully complete for an agent to anticipate the response.

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 includes an Args section that adds meaning beyond the schema's titles, explaining 'name' as category name and 'category_set_id' as parent category set with default 0. This compensates for the 0% schema description coverage, though it could provide more detail like constraints or allowed values.

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?

Clearly states 'Create a new category' with a specific verb and resource. Distinguishes from siblings like 'create_category_set' which creates a set, not a single category. The mention of calling list_categories first further clarifies its purpose.

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 a precondition (call list_categories to avoid duplicates) but does not explicitly state when to use this tool versus alternatives like 'create_shared_category' or 'join_shared_category'. The guidance is implied but not complete.

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