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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is covered without the description. The description adds nothing about response shape, time window semantics of 'uptime', or auth requirements.

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?

It is short and front-loaded, but the first sentence is duplicated verbatim, so a nontrivial fraction of the text is pure repetition rather than information.

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 read endpoint with no output schema, no annotation gap, and two undocumented parameters, the description should at least say what the uptime payload represents and any time-window parameters. It gives the agent nothing to invoke with beyond the raw path.

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% for a tool with a free-form 'query' object and an empty 'params' object. The description does not describe either; it merely defers to describe_operation, which is not the same as explaining parameter semantics.

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 is literally the endpoint path repeated twice plus an operation ID, which restates the tool name and title. It never explains what 'uptime' data the endpoint returns or how it differs from siblings such as get_support_status or get_support_incidents_history.

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?

No when-to-use guidance, no prerequisites, and no named alternative. The only actionable sentence points at describe_operation for request schemas, which is a schema lookup hint rather than selection guidance.

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