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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It says nothing about side effects, return values, input handling, or the fact that several parameters are explicitly discarded; the 'discarded' hints live only in the schema, not the description.

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 text is short but under-specified, not genuinely concise in a helpful way. It is a single trailing phrase with no structure and no operational detail, so brevity comes at the expense of clarity.

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 has eight heterogeneous parameters and no output schema or annotations, yet the description only states a vague subject. An agent cannot determine what inputs are required, how they are used, or what the tool returns.

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?

Every parameter has a meaningful schema description with coverage near 100%, so the baseline is 3 even though the description adds no parameter-level meaning. The description itself does not explain how any parameter relates to the catalog, but the schema compensates.

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 that restates the tool name ('catalog') and never states a verb or operation. It tells the agent the topic (HTTP status codes) but not whether calling the tool returns a listing, checks an input, or maps a parameter to a 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 versus siblings like fetch-status, domain-shape, or validate-json. No exclusions, alternatives, or usage conditions are mentioned.

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