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

With no annotations available, the description carries the full burden of behavioral disclosure, but it only says 'short catalog.' It does not state that the tool is read-only, that most input parameters are discarded, or whether any network or shape-checking occurs. The schema hints at discarding, but the description itself does not.

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, but it is under-specified rather than efficiently complete. It earns its single sentence, yet omits behavioral and usage details that an agent 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?

There is no output schema, and the description does not say what the tool returns or how to invoke it meaningfully. With seven unrelated parameters and no return-value explanation, the definition is not complete enough for confident tool selection.

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 input schema describes all seven parameters, so the schema already provides high coverage. The tool description adds no parameter meaning, and the odd mismatch between a status-code catalog and parameters like city, feed, and json is left unexplained.

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 (common HTTP status codes) and clearly implies a catalog/lookup tool, which distinguishes it from siblings like fetch-status or web-fetch. It lacks an explicit verb like 'returns' or 'looks up,' but the resource and function are reasonably 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?

No guidance is given on when to use this tool versus alternatives such as fetch-status, web-fetch, or validate-json. There is no context, no exclusion, and no mention of preferred scenarios.

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