update_vendor

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

No annotations are present, so the description carries the full burden of disclosing behavioral traits. It only says 'update,' which implies mutation, but it does not state whether the update is partial or full replacement, whether it is idempotent, what permissions are required, or what the response looks like.

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 concise and free of filler, but it achieves brevity by merely restating the tool name. It is structurally simple and front-loaded, yet it provides so little content that the conciseness is not a meaningful strength.

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 two-parameter mutation tool with no annotations and no output schema, this description is severely incomplete. An agent has no way to know what fields belong in the body, whether a full replacement is required, what the success or error responses are, or how this operation behaves in relation to other vendor operations.

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?

Schema description coverage is only 50%, and the description does not compensate. The 'id' parameter has no schema description and no explanation in the tool description, while the 'body' parameter is vaguely described as a pass-through request body without enumerating acceptable vendor fields or update semantics.

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 'Update a vendor' simply restates the tool name 'update_vendor' in sentence form, so it adds no information beyond the identifier. It nominally identifies the verb and resource, but because it is a direct tautology of the name, it does not meaningfully distinguish itself from siblings such as create_vendor or get_vendor beyond what the name already communicates.

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 offers no guidance about when to use this tool versus alternatives like create_vendor, get_vendor, or list_vendors. There is no context about prerequisites, common workflows, or cases where a different vendor-related tool should be preferred.

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