shutdown

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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the risk profile is covered. The description adds real value by naming the environment requirements (trusted owner, interactive desktop), but it says nothing about what the shutdown actually does, whether it can be cancelled, or how failures surface.

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?

Two short sentences with no padding, and the effective constraints are front-loaded. It is efficient, though the terseness contributes to the missing detail noted elsewhere.

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 destructive, non-idempotent, open-world tool with no output schema, the description covers the environment gate but omits what happens on success/failure and what the flags integer means. Adequate as a minimum-viable definition, not sufficient for confident invocation.

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 100%, so the single 'flags' parameter is nominally documented, but both the schema text ('Shutdown flags') and the description are tautological. The integer is effectively opaque (no enum, no EWX_* examples), so the description fails to compensate for a semantic gap it is well positioned to fill; the 100% coverage baseline keeps this at 3 rather than lower.

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 phrase "Windows AutoIt shutdown" names the action and platform but reads as a restatement of the tool name rather than a specific verb+resource statement (e.g. 'initiates a system shutdown/restart on the local Windows host'). It is clear enough that the tool touches shutdown behavior, but an agent gets no scope detail such as whether it shuts down, restarts, or logs off.

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 supplies prerequisites ('trusted owner', 'interactive Windows x64 desktop'), which is genuine pre-call context, but it never says when to use this tool versus doing nothing or using processClose/run siblings. Usage is implied by the prerequisites rather than stated with exclusions.

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