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

The readOnlyHint annotation already communicates the read-only nature, and the description aligns with it by saying 'Get'. The description adds the endpoint and scopes the result to the aggregate status type, but it does not disclose additional behavioral details such as response format, auth requirements, or rate limits. This is acceptable given the annotation coverage.

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 concise sentence with the core action front-loaded, followed by the precise endpoint. There is no wasted text, and every element contributes to understanding the tool's purpose.

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?

For a simple read-only tool with one optional parameter, the description is nearly complete: it states what is returned (aggregate status type) and how to invoke it. However, it does not explicitly differentiate itself from the closely related get_summary or get_service_status tools, so slightly more contextual guidance would make it fully complete.

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 schema provides 100% coverage for the only parameter, subdomain, including its meaning and override behavior. The description does not add significant parameter-level semantics beyond what the schema already states, so a baseline score of 3 is appropriate.

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 states the action ('Get') and resource ('current overall status'), and the parenthetical 'aggregate status type' helps distinguish it from per-service or summary tools. The endpoint is also provided, but it does not explicitly name or contrast sibling tools, which prevents a top score.

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 implies when to use the tool—when the overall status is needed—but provides no explicit guidance about when not to use it or which sibling alternative to choose. The phrase 'aggregate status type' offers some context, but the description does not mention get_service_status or get_summary.

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