fullscreen_window

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

No annotations are provided, and the description does not disclose any behavioral traits beyond the basic action. It does not state what happens if the window is already in the requested fullscreen state or any potential side effects.

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 concise with four sentences, using a clear docstring format. Every sentence is necessary and well-structured, with no wasted words.

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?

Given the presence of an output schema (not shown), the description need not explain return values. It covers the essential steps and parameters. Minor omission: it could mention that the window must support fullscreen, but overall it's complete for a simple tool.

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 has no descriptions for parameters (0% coverage), so the description fully compensates by explaining 'window_id: The window ID.' and 'fullscreen: True to enter fullscreen (default), False to exit.' This adds essential meaning.

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's action: 'Enter or exit fullscreen for a window.' The verb 'Enter or exit' and the resource 'fullscreen for a window' are specific, and it distinguishes from sibling tools like move_window or resize_window.

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 instructs to 'Use windows() to find the window ID first,' providing a clear prerequisite. It does not explicitly mention when not to use or alternatives, but the context is clear for this simple toggle.

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