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

With no annotations, the description must carry behavioral disclosure; it states that the response body is discarded, which is useful. But it does not mention side effects, errors, request/response details, or any safety-relevant behavior such as auth/rate limits.

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 short and front-loaded, with no filler; the key output limitation ('Body discarded') is stated early. More explanation would help, but the existing text is tightly structured.

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 nine optional parameters, no output schema, and no annotations, the description is far from complete. It fails to explain which parameters are used for the HTTP fetch, what the response format looks like, or how the unrelated-looking parameters relate to the tool's purpose.

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?

All nine parameters have schema descriptions, but many appear unrelated to the stated HTTP-status/content-type purpose (city, zone, query, json, path, ref). The descriptions like 'discarded after the call' add odd context rather than clarifying how each parameter affects the fetch, so parameter semantics are weak.

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 names the operation (fetching HTTP status/content type) and the resource (public URL), and notes the body is discarded. It does not explicitly contrast with sibling fetch/URL-check tools, so it is slightly under-specified but still clear.

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 gives no direct guidance about when to use this tool instead of alternatives like fetch-status or normalize-url, and no conditions or exclusions. The only implicit cue is that body content is discarded, which is not enough to orient an agent.

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