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

With no annotations provided, the description carries the full burden, and it only reveals that the output is a short set of common HTTP status codes. It does not explain input behavior, return format, side effects, or why seven unrelated parameters are accepted.

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?

While the text is only one sentence long, it is under-specified rather than appropriately concise. Given a seven-parameter input schema and multiple sibling tools, the single sentence does not earn its place because it omits crucial orientation about how to invoke the tool.

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 description is seriously incomplete for a tool with seven diverse parameters and no output schema. It does not explain what the catalog returns, how any input affects the result, or how this tool fits with the surrounding shapes and fetch utilities.

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 already provides a description for every parameter, so schema_description_coverage is high and the baseline is 3. The tool description adds no parameter meaning and does not explain how ref, url, city, feed, host, json, or path relate to a catalog of HTTP status codes.

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 is a noun phrase rather than an action statement, so it does not state what the tool does. It essentially restates the name 'status-catalog' as 'catalog of common HTTP status codes', and does not distinguish this catalog 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 about when to use this tool versus alternatives such as fetch-status or browser-url-ok. No conditions, exclusions, or comparisons are provided, so an agent has no basis for selecting this tool correctly.

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