stop_blinker

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

No annotations are provided, so the description carries the full behavioral disclosure burden. It states the core effect—stopping the Ethernet port blinker—but does not mention idempotency, failure behavior, prerequisites, or any side effects. For such a simple action this is minimally adequate, but not rich.

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 six-word sentence that front-loads the action and object. Every word is necessary, and there is no filler or redundant explanation.

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?

With zero parameters and an output schema present, the agent mainly needs to know the tool's intent, which the description supplies clearly. It could be more self-contained by referencing the blinker lifecycle, but the description is complete enough for a trivial control command.

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 tool has zero parameters, so there are no parameter semantics for the description to explain. The schema already fully covers the empty parameter set, and the description does not need to compensate for any parameter documentation gap.

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, 'Stop', and identifies the exact resource, 'the Ethernet port blinker'. It clearly distinguishes itself from sibling tools like start_blinker and get_blinker_status by naming the action and object.

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 gives no explicit when-to-use guidance and does not mention start_blinker or get_blinker_status as alternatives. Usage is only implied by the verb and resource, which is simple enough for an agent to infer but still leaves contextual decision-making to the agent.

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