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

No behavioral information is provided. The description does not state whether the tool is read-only, has side effects, or what it does with input parameters. With no annotations to fall back on, the description carries the full burden and fails to disclose any behavioral aspects.

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, which is concise but severely underdeveloped given the tool's complexity (9 parameters). It lacks structure and does not front-load critical details; the brevity is not matched by clarity or completeness.

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?

The description is completely inadequate for the tool's complexity. It does not explain what the catalog contains, how to interpret results, the role of the parameters, or any output structure. With no output schema or annotations, this sparse description leaves nearly all contextual information missing.

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?

The parameters (ref, url, city, feed, host, json, path, zone, query) have descriptions in the schema, but these descriptions are generic and unrelated to HTTP status codes. The tool description does not explain how any parameter affects the catalog output, making the parameter semantics confusing and non-informative.

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 it provides a catalog of common HTTP status codes, which indicates the resource and general purpose. However, it lacks a specific verb (e.g., 'retrieve', 'list') and does not explain how the tool relates to its many parameters. It is distinguishable from siblings like 'fetch-status' but not fully explicit.

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 does not mention any scenarios, contexts, or selection criteria, leaving the agent without any direction on when this tool is appropriate.

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