hide_app

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

With no annotations provided, the description carries the full burden, but it only states the core action without disclosing side effects, prerequisites, or error behaviors. For example, it does not say what happens if the app is not running or whether all windows are hidden. This is minimal behavioral disclosure.

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 concise two-sentence definition with no filler, front-loading the core action in the first sentence. The parameter breakdown is structured and easy to parse.

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 one-action tool with an output schema present, the description provides the essential information—what the tool does and what the input means. However, it omits behavioral caveats and usage guidance, leaving some gaps for an agent that may need to handle edge cases.

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 has 0% description coverage, so the description must compensate. It does so by providing a one-line explanation for the app_name parameter ('Name of the application to hide'), which adds context beyond the schema's title 'App Name'. However, it lacks details such as whether it accepts a process name or display name.

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 'hide' with a clear resource 'an application's windows', distinguishing it from sibling tools like launch_app, quit_app, and list_running_apps. There is no ambiguity about the action.

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 does not explicitly state when to use this tool versus alternatives, nor does it mention any prerequisites or exclusion cases. However, the tool's purpose is self-evident, and the usage context is implied by the description.

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