create_category

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'Create a new...', which implies a write operation but does not mention side effects, authentication needs, or whether the operation is idempotent. For a mutation tool, this is minimal transparency.

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, concise sentence that immediately states the purpose. It is front-loaded and efficient, with no extraneous words. However, it is too brief and sacrifices informativeness for brevity.

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's complexity (7 parameters, no output schema, no annotations), the description is incomplete. It does not explain how parameters like 'group_id' or 'archived' affect the behavior, nor does it describe the return value or success indicators. More context is needed for effective use.

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 schema has 7 parameters with 0% description coverage, meaning the description adds no explanation for any parameter. The description does not compensate for the lack of schema descriptions. It does not clarify the meaning of 'is_income', 'exclude_from_budget', etc., which are non-obvious. The baseline is low due to low coverage.

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 the action ('Create') and the resource ('a new Lunch Money category'), specifying the verb and object. It distinguishes from sibling tools like 'update_category' and 'get_categories' by implying the creation operation. However, it lacks additional context such as the domain or scope.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of prerequisites, such as requiring an existing group_id, or when to use 'update_category' instead. The name and siblings imply a create operation, but no explicit context is given.

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