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 does not state whether the tool is read-only, whether it performs any network or disk access, what output it returns, or whether parameters are discarded. The catalog nature implies passivity, but that is not explicit.

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 one short sentence, so it is concise, but the brevity is a symptom of under-specification rather than efficient packaging. It contains no front-loaded usage information and leaves the mismatched schema unexplained.

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 no annotations, no output schema, no required properties, and 18 optional-looking parameters, this one-line description is far from complete. An agent has no definition of what a successful call looks like, what the tool returns, or which parameters are relevant.

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 per-property descriptions, but the tool description does not map any of the 18 properties to the status-code catalog, and no property obviously represents a status code. The 'http' property refers to an HTTP method name, not a status code, so calling the tool with the correct parameter is largely guesswork.

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 domain—HTTP status codes—and implies the tool provides a catalog, but it uses no action verb and does not say how to query it. It reads almost as a restatement of the tool name and does not distinguish it from sibling tools like fetch-status or web-fetch.

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 alternatives, nor any hint about what input it expects. An agent cannot tell whether to pass a status code, a URL, or a search query, and no exclusions or alternative tool names are mentioned.

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