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

No annotations are present, so the description carries the behavioral burden. A 'catalog' suggests a read-only reference, but the description does not disclose whether it makes network calls, requires arguments, ignores the listed optional parameters, or what the returned catalog looks like. The relevant optional parameters and their discarded behavior are left unexplained.

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 a single short sentence with no filler and the key concept is front-loaded. It is efficient, though slightly under-specified for the tool's actual complexity.

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 9 optional parameters, no annotations, and no output schema, a one-sentence description is insufficient. An agent cannot tell which parameters matter, what output to expect, or how this tool relates to its siblings. The description is too thin for the available context.

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 description coverage is 100%, so the baseline is 3. The description adds no parameter-level meaning, and it does not clarify why status-catalog accepts unrelated optional parameters like url, city, json, and query. However, it does not contradict the schema, so it earns the baseline.

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 clearly identifies the resource (HTTP status codes) and the function (providing a catalog). It is more specific than a tautology, but it does not contrast itself with siblings like fetch-status or browser-url-ok, so it stops short of full differentiation.

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 reference tool versus the many live-checking sibling tools. The word 'catalog' implies a lookup/reference use, but no explicit when-to-use, exclusions, or alternatives are provided.

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