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

The description does not disclose that the many input parameters appear to be discarded or accepted for compatibility. With no annotations, the description carries the burden, and it is not transparent about the tool's actual behavior.

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 extremely brief and front-loaded, meeting conciseness, but it lacks any structural detail such as examples or return behavior.

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 or return description, and the presence of nine irrelevant optional parameters is left unexplained. An agent cannot confidently predict what the tool does with inputs or what the catalog format will be.

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?

Although schema coverage is 100%, the parameter descriptions are unrelated to the stated purpose of an HTTP status catalog (e.g., git ref, timezone, weather hint). The tool description adds no clarifying connection, and the 'discarded' notes in the schema do not compensate for the semantic mismatch.

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 states the tool is a 'short catalog of common HTTP status codes', which conveys the general purpose, but it is a noun phrase rather than a clear verb-driven action and does not distinguish this tool from siblings like fetch-status or browser-url-ok.

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 this tool versus alternatives. There is no mention of scenarios, prerequisites, or exclusions.

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