cloak_press

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

The description only says 'Press a keyboard key' without detailing how the keypress is simulated, whether it's a press-and-release, if it requires focus on an element, or any side effects. With no annotations, more transparency is needed.

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 concise sentence with no wasted words. It is front-loaded with the action. However, it could be slightly expanded to improve completeness without losing conciseness.

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 simple tool with one parameter and no output schema, the description adequately covers the core function. However, it lacks details about behavioral semantics like event dispatching, which could be important for an AI agent.

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 schema describes 'key' as 'Key to press.' The description adds value by listing common key examples (Enter, Tab, Escape, ArrowDown), helping the agent understand valid inputs beyond the schema's generic description.

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 clearly states the tool presses a keyboard key and provides examples like Enter, Tab, Escape, ArrowDown, etc. It distinguishes from sibling tools such as cloak_click (mouse click) and cloak_type (typing text).

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?

No explicit usage guidance is given. The context of sibling tools implies it should be used for single key presses rather than typing sequences or mouse actions, but there is no direct statement on when to use or not use this tool.

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