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

No annotations are provided, so the description carries the full burden of behavioral disclosure. 'Check...uptime' implies a read-only status query but does not explain what the agent will receive, what 'uptime' means in this context, or whether any side effects exist. This is too thin to fully orient the agent.

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 short and front-loaded, which is appropriate for a no-parameter tool. However, the opening 'Platform Uptime:' label is redundant with the tool name and the rest of the sentence, adding no new 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 zero-parameter, simple status-check tool, the description is minimally viable: an agent can infer the action and resource. But with no output schema and no annotations, the description does not clarify what kind of uptime result is returned, leaving a clear but acceptable gap.

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 input schema is empty and there are no parameters, so the description has no parameter documentation burden. The zero-parameter baseline of 4 applies.

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 uses a specific verb and resource: 'Check minia2a platform uptime.' This tells an agent what the tool does. However, it does not differentiate itself from sibling tools like x402-uptime or service_discovery, so some selection ambiguity remains.

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 when-to-use guidance, no mention of alternatives, and no exclusions. The description implies the tool is for checking platform uptime, but an agent receives no help deciding between this and related monitoring tools.

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