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

No annotations are present, so the description carries the full behavioral disclosure burden. It does not state whether the tool is read-only, what it returns, how the nine inputs are handled, or what side effects, if any, exist. The word 'catalog' implies a static resource, but that implication is not stated.

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 concise and front-loaded, with no filler words. It loses points only because the brevity is not accompanied by the richer behavioral and usage context the tool actually needs.

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?

The tool definition is not complete for its complexity: seven words and none of nine optional parameters, no annotations, and no output schema. It doesn't say what the returned catalog looks like, whether callable with no required arguments, or what each parameter does if supplied.

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 tool description itself adds no parameter-level meaning. The description neither helps select among the nine optional parameters nor explains why inputs like city, JSON, or query relate to an HTTP status 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 content (common HTTP status codes) but stops at a noun phrase and never states an operation such as 'returns', 'lists', or 'looks up'. It gives a rough idea of what the tool is about, but leaves the actual invocation purpose to inference.

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 about when to choose this tool, when not to use it, or how it relates to siblings like fetch-status or web-fetch. The phrase 'short catalog' only weakly implies that the agent should call it when HTTP status code knowledge is needed.

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