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

With no annotations, the description carries the burden of behavioral disclosure. The '(offline)' qualifier adds some behavioral context, but it is ambiguous—it could mean the tool works offline, or that the service is currently unavailable. No contradiction with annotations exists.

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 terse sentence with the core action front-loaded. The redundant 'HTTP Status:' prefix is minor, but overall the description is concise and avoids filler.

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 tool is simple, has one parameter, and an output schema exists, so the description does not need to explain return values. However, it leaves the parameter format unspecified and does not clarify when to choose this tool over sibling HTTP-related tools, which limits completeness.

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 description coverage is 0%, and the description does not explain the 'q' parameter. It only implies via the tool's purpose that 'q' should be an HTTP status code, but it does not specify format, examples, or accepted values.

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 a specific action and resource: 'Explain an HTTP status code'. It is clear what the tool does and its domain. It does not explicitly differentiate it from sibling tools like httpcode or httpmethods, but the core purpose is unambiguous.

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 this tool versus alternatives such as httpcode, httping, or httpmethods. The parenthetical '(offline)' hints at a capability but does not explain the appropriate use context or exclusions.

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