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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions 'offline', which is a useful behavioral trait, but it does not disclose what the tool returns, whether it accepts a code like 404 or a name like 'Not Found', or whether it performs any network access. The behavior is under-specified.

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 front-loaded: the resource and purpose appear in the first few words. It earns its place with the 'offline' qualifier. However, it is so terse that it sacrifices necessary detail, so it is not a 5.

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 has one parameter with zero schema description coverage, no annotations, and a sibling 'httpstatus' that likely overlaps. The description does not explain the expected input format, the output shape, or how it differs from the sibling. For a simple lookup tool this is minimal but still leaves an agent guessing.

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%, so the description must compensate for the undocumented 'q' parameter. The description says 'HTTP status code' but does not clarify whether 'q' should be a numeric code (e.g., 404) or a textual name (e.g., 'not found'), nor does it give examples or format constraints. This is a significant gap for a single-parameter tool.

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 'HTTP Status Code: HTTP status code meaning & family (offline)' states the resource (HTTP status codes) and the action (look up meaning and family), so an agent can roughly tell what it does. However, it doesn't use a strong verb like 'look up' or 'explain', and it doesn't distinguish itself from the sibling 'httpstatus' or 'httping' tools, which likely overlap in purpose.

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 gives no guidance on when to use this tool versus alternatives like 'httpstatus' or 'httping'. The word 'offline' hints that it may work without network access, but there is no explicit when-to-use or when-not-to-use guidance, and no mention of what input format is expected.

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