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

No annotations are provided, so the description carries the full burden. It discloses no behavioral traits—no mention of side effects, return format, or how parameters affect output. The single sentence provides no behavioral transparency beyond the label 'catalog'.

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 concise sentence, which is efficient. However, it is under-specified for a tool with nine parameters and no output schema. It is concise but not structured to convey necessary information.

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?

For a tool with nine parameters, no output schema, and no annotations, this description is severely incomplete. It does not explain what the parameters do, what the tool returns, or any behavioral context. An agent cannot reliably invoke this tool based on the description alone.

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 each parameter is described in the schema. The tool description adds no parameter semantics, but the schema already handles it. Baseline of 3 is appropriate; the description does not compensate for any gaps.

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 provides a short catalog of common HTTP status codes, which is a clear purpose. However, it does not explain how the nine parameters relate to this purpose, nor does it differentiate from sibling tools like fetch-status or web-fetch. The purpose is clear but incomplete.

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 on when to use this tool versus alternatives. The description lacks any context about appropriate use cases, prerequisites, or exclusions. An agent would have no idea whether to choose this over sibling tools.

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