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

No annotations are present, so the description carries the full burden of disclosing behaviors, but it mentions no side effects, input handling, output format, permissions, rate limits, or discriminable operational traits. The parameter descriptions say values are 'discarded,' yet the tool-level description never conveys this.

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 one-sentence description is short, but brevity here is under-specification rather than genuine concise clarity. It front-loads no actionable operational detail and omits essential invocation context.

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?

Given nine optional parameters, no annotations, no output schema, and rich sibling-tool alternatives, this description is seriously incomplete. An agent cannot determine what inputs are meaningful, what response to expect, or how this tool differs from tools like fetch-status or browser-url-ok.

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 of 3 applies even though the description itself adds no parameter-level meaning. The schema documents each parameter, but the tool description does not tie any of them to the 'catalog' purpose.

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 'Short catalog of common HTTP status codes' is essentially a restatement of the tool name status-catalog; it lacks a specific verb or the resource/action an agent would act on. It does not say how the nine parameters relate to the catalog or distinguish this tool from sibling status/validation tools.

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 explicit guidance on when to use this tool, when not to use it, or which sibling tool is the better alternative. The description simply states what the catalog is, not when an agent should invoke it.

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