Cancel pending shutdown/restart

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

No annotations are provided, so the description carries the behavioral disclosure burden. It clearly discloses the operation (aborting) and its precondition (a pending countdown), which is the key behavior an agent needs. It does not state the outcome if no countdown is pending, though that is a minor gap for a simple cancel action.

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 sentence, front-loaded with the action and target, with no filler or repetition of the tool name title. Every word earns its place.

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 no-parameter cancellation tool, the description gives the essential precondition and target. There is no output schema, so return behavior is not described, but the simplicity of the operation makes the description adequate.

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, and the schema is empty with 100% coverage. There is nothing for the description to add about parameter meaning, so the 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 the specific verb 'Abort' and names its two targets, shutdown_pc and restart_pc, with the qualifying condition 'still in its countdown.' This clearly identifies what the tool does and distinguishes it from the shutdown/restart siblings.

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 establishes when this tool applies: after a shutdown_pc or restart_pc has been initiated and before its countdown finishes. It does not explicitly list alternative tools or when not to use it, but the context is clear from the countdown condition.

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