Next Unraid systemMetricsCpuTelemetry event

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

Annotations already establish read-only, idempotent, non-destructive behavior. The description adds valuable one-shot subscription semantics: it waits, returns one bounded payload, and disconnects. It does not contradict annotations, though it omits timeout or no-event behavior.

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?

A single, information-dense sentence with no filler. The core behavior is front-loaded ('Wait for the next event') and every remaining clause adds meaningful detail.

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-input, one-shot subscription tool, the description is nearly complete. It covers the operation's lifecycle but does not describe the payload shape or what happens if no event arrives; with no output schema, a bit more detail about the return value would be ideal.

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?

There are zero parameters, and schema coverage is 100%, so the empty input schema is fully self-explanatory. The description's mention of a 'fixed GraphQL subscription' reinforces that this tool has no configurable inputs.

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 states a specific action ('Wait'), a precise resource ('this fixed GraphQL subscription'), and a well-defined terminal behavior ('return one bounded payload, then disconnect'). This clearly identifies it as a one-shot telemetry event tool and distinguishes it from indefinite subscriptions or query tools.

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 makes it clear this is for retrieving a single next CPU telemetry event and then closing the subscription. It does not explicitly name alternatives or state when not to use it, but the intended usage is strongly implied.

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