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

No annotations are provided and the description discloses no behavioral traits. It does not state whether the tool is read-only, what it returns, whether inputs are used or discarded, or any side effects. 'Short catalog' alone does not carry the behavioral disclosure burden.

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 short sentence with no filler or repetition. It front-loads the core subject, though it is under-specified rather than improperly verbose.

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?

With 9 optional parameters, no output schema, no annotations, and many sibling tools, this one-sentence description is far from complete. An agent cannot determine what to pass, what the result will look like, or how this tool differs from related status and URL-checking tools.

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 the baseline is 3. The description itself adds no parameter meaning, but each parameter has a textual description in the schema. However, the description does not explain why parameters like ref, city, or feed relate to an HTTP status code catalog.

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 identifies the resource as a catalog of common HTTP status codes, so an agent can roughly infer the topic. However, it lacks a verb: it does not say whether the tool lists, explains, maps, or validates status codes, and it does not differentiate itself from siblings like fetch-status.

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?

There is no guidance on when to use this tool versus any of the many sibling tools. It does not mention prerequisites, expected inputs, or cases where another tool such as fetch-status would be more appropriate.

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