update_vendor_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 only says 'Update a vendor category,' which adds no context beyond the mutation implied by the verb. There is no mention of required permissions, reversibility, or response behavior, making it nearly non-informative.

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 declarative sentence with no fluff, making it concise. However, it is essentially a restatement of the tool name and lacks any structural detail about parameters or usage. It is not overly verbose, but it under-specifies to the point of being minimally adequate.

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 presence of a nested object parameter, missing annotations, and no output schema description, the context is severely incomplete. The description does not mention required fields, the meaning of category_data, or any post-update behavior. An agent would not have enough information to use the tool correctly.

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 0% description coverage, and the description does not compensate. It does not explain the purpose of category_id or the structure of category_data, which is an arbitrary object with additionalProperties true. This leaves the agent with no understanding of what data to provide or what fields are expected.

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 tool updates a vendor category, using a specific verb and resource. It is distinguishable from sibling tools like create_vendor_category and list_vendor_categories, though it lacks scope details about what fields can be updated.

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. It does not mention prerequisites, exclusions, or context that would help an agent decide between update and create operations. The clarity is minimal and leaves the agent without strategic direction.

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