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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says the tool is a 'short catalog' and does not mention that all nine input parameters are effectively discarded, that no arguments are needed, or what output the agent should expect.

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 only one sentence and easy to skim, which is efficient. However, it is under-specified beyond a label-like phrase, so the brevity borders on insufficient rather than excellently concise.

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 no output schema and no annotations, the description leaves important context missing: how to invoke it, that the parameters are ignored, and what kind of catalog data will be returned. An agent would need to guess or call the tool experimentally to understand its behavior.

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 even though the description adds no parameter detail. The schema documents each parameter individually, though the description fails to clarify that none of them are relevant to retrieving the 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 what the tool provides. However, it uses a noun phrase rather than a specific action verb and does not explicitly differentiate it from siblings 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 about when to use status-catalog versus related tools such as fetch-status, browser-url-ok, or normalize-url. The description implies a static reference lookup, but it never states the intended invocation context or when an alternative should be preferred.

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