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 'Short catalog' and does not mention output shape, side effects, network/disk access, or how the parameters relate to behavior. The schema hints that several inputs are discarded, but the description itself discloses nothing.

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 text is short, but this is under-specification rather than skillful conciseness. A single phrase does not adequately support a 9-parameter tool with no output schema and no usage guidance, so the brevity sacrifices essential information.

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 tool with 9 optional parameters, no annotations, no output schema, and a large sibling set, this description is severely incomplete. It fails to explain the request/response contract, the role of each parameter, or how this tool differs from status-related siblings.

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 100%, so each parameter already has an individual description, meeting the baseline. However, the tool description adds no meaning tying parameters like city, zone, or query to the stated purpose of cataloging HTTP status codes.

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 is essentially a noun phrase that restates the tool name: 'Short catalog' closely mirrors 'status-catalog'. It adds that the domain is HTTP status codes, but it lacks a verb indicating what the tool does (look up a code, list codes, validate a status?), and the 9 unrelated input parameters further obscure the 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?

No guidance is given on when to use this tool versus siblings like fetch-status or browser-url-ok. There is no mention of intended context, preconditions, or exclusions, so an agent has no basis for choosing or invoking it appropriately.

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