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

No behavioral details are disclosed. The description neither states that the tool is read-only nor describes any side effects, return format, or edge cases, and no annotations are provided to supplement 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 description is a single short sentence that immediately states the tool's purpose. It is well within acceptable length and has no redundant or verbose content.

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 the tool has nine optional parameters and no output schema or annotations, the description is severely incomplete. It fails to explain what the catalog contains, how the parameters are used, or what the caller should expect as a result, leaving the agent without enough context to invoke it correctly.

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 nine parameters have descriptions that are entirely unrelated to the stated purpose of cataloging HTTP status codes (e.g., 'City name for a public weather hint'). These descriptions do not clarify how the parameters affect the tool's behavior, making them confusing and semantically inconsistent with the tool's function.

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 tool as a catalog of common HTTP status codes, which is a specific resource. However, it lacks an explicit verb like 'returns' or 'lists,' and it does not differentiate itself from related sibling tools such as fetch-status or web-fetch.

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?

The description provides no guidance on when to use this tool versus any alternative. There is no mention of conditions, prerequisites, or comparisons to sibling tools, leaving the agent without direction on selection.

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