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

No annotations are present, so the description carries full responsibility for disclosing side effects, output behavior, or operational constraints. It discloses none of these.

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 concise, but brevity is not useful here because it omits essential information. The single sentence does not earn its place as a functional tool description.

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 unrelated schema parameters and lack of output information, the description is severely incomplete. An agent would not know how to invoke the tool or interpret its result.

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 description adds no meaning to the input schema. Moreover, the schema properties (url, host, json, zone) appear unrelated to the stated 'Meaning of HTTP 502' purpose, creating confusion rather than clarity.

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 'Meaning of HTTP 502' is a noun phrase rather than an action-oriented statement. It vaguely identifies the topic but does not specify what the tool actually does with the supplied parameters, and it fails to distinguish itself clearly from sibling tools like status-catalog.

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 status-catalog or validate-json. The description provides no context about appropriate invocation conditions.

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