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

With no annotations, the description carries the full burden of behavioral disclosure. 'Short catalog' weakly implies a read-only reference operation, but nothing is said about how the four unrelated inputs are handled, what the output looks like, or whether side effects occur.

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 front-loaded, but it is under-specified rather than efficiently complete. It earns no extra credit because it conveys little beyond the tool name.

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?

A tool with four heterogeneous parameters, no output schema, and no annotations requires substantial contextual explanation. The one-line description does not explain how to invoke the catalog, what the parameters mean in this context, or what the agent should expect in return.

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 coverage is 100%, so the baseline is 3. Each parameter has its own description, but the tool description adds no connection between those parameters (url, host, json, zone) and the stated purpose of listing HTTP status codes, so the parameter semantics remain confusing.

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 as a catalog of common HTTP status codes, which is more informative than the bare name. However, it lacks a verb such as 'returns' or 'lists' and does not differentiate it from sibling tools like catalog-tools or citation, so the purpose is only moderately 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 about when to use status-catalog versus any sibling tool. The description does not state appropriate inputs, expected use cases, or exclusions, leaving the agent to guess.

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