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

No annotations are present, so the description carries the full burden; it only says 'short catalog', which hints at a lightweight read-only reference but says nothing about output, side effects, or interaction with the many input parameters. This is minimal disclosure, not meaningful transparency.

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 very short and has no wasted words, but it is under-specified for a tool with seven distinct parameters and many siblings. Being brief is not the same as being appropriately sized.

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 no output schema, no annotations, and a seven-parameter input schema whose parameters are not connected to the stated purpose, the description is far from complete. An agent cannot determine what inputs to provide or what response to expect.

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 tool description adds no parameter information, but every parameter in the input schema has its own description, so schema coverage is high. With the schema carrying the parameter semantics, the baseline of 3 is appropriate; the description does not need to compensate.

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 identifies the resource (HTTP status codes) and scope (common codes), so it is not a tautology. However, it is a noun phrase without a clear verb or return statement, and the input schema's many unrelated parameters make it unclear what an agent should actually do with the tool.

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 status-catalog versus siblings like fetch-status, normalize-url, or web-fetch. The only implied context is 'if you need common HTTP status codes', but no exclusions or alternative mentions are provided.

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