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

No annotations are provided, so the description carries the burden of disclosing behavior. It does state that the operation is an emergency reset and safe to call anytime, which is useful context, but it does not explain potential side effects, whether it affects the OS-level key state or only the tool's internal state, or what the response will be.

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 two short, front-loaded sentences with no filler. The core action and emergency-reset intent come first, and the safety reassurance is appended efficiently.

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 tool with an output schema, the description is complete: it names the action, the scope, the emergency-reset intent, and the safety profile. An agent has everything needed to invoke it correctly.

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 zero parameters, so the description does not need to explain parameter semantics. The phrase 'every held key and button' also conveys the scope of the operation.

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 ('Release') and a precise resource ('every held key and button'), and adds the clarifying parenthetical 'emergency reset'. This makes the tool's purpose unmistakable and distinguishes it from siblings like get_held, which queries held state rather than clearing it.

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 phrase 'emergency reset' implies the intended use case, and 'Safe to call anytime' provides clear, unconditional context for when it can be used. However, it does not explicitly name alternatives or state when not to use it.

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