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

With no annotations, the description must explain behavior, but it only names a catalog and gives no indication of side effects, return format, errors, or read-only nature. The parameter descriptions hint at discarded inputs but do not make the tool's behavior transparent.

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 the schema is compact with one-line parameter descriptions. The structure is clear, though the terse noun-phrase style limits its informative value.

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?

With nine optional parameters, no output schema, and no annotations, the description is far too incomplete. It omits what the tool returns, how inputs relate to the catalog, and any operational context needed to call it correctly.

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?

Each parameter has a one-line description, so schema coverage is nominally 100%, but the parameters (Git ref, URL, city, feed, host, JSON, path, timezone, query) are unrelated to an HTTP status code catalog and several are described as 'discarded'. This adds little usable semantic meaning for invoking the tool.

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 ('Short catalog...') without a verb, so it doesn't state what action the tool performs. It identifies a topic but not whether it lists, fetches, or returns status codes, and it does not distinguish this from sibling tools like fetch-status.

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 on when to use this tool instead of alternatives. No conditions, prerequisites, or selection criteria are provided despite many closely related sibling tools.

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