dismiss_all_popups

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

With no annotations, the description carries the full behavioral burden. 'Immediately' usefully signals that dismissal is instantaneous and non-interactive (no per-popup confirmation), but it says nothing about what happens when no popups exist, whether the action is reversible, or whether it affects only the focused screen.

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?

A single, front-loaded sentence with no filler. Every word ('immediately', 'every', 'currently shown') contributes scope or timing information.

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, no-output tool this is nearly complete: the agent knows the effect, the scope, and the timing. The one gap is the no-popups edge case, which the description leaves unstated.

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 tool takes zero parameters, so the baseline is 4. The description correctly implies no targeting input is needed because all on-screen popups are handled.

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?

Specific verb ('close') plus resource ('every popup currently shown on screen') with a clear scope qualifier. The 'every... currently shown' phrasing separates it from the sibling show_popup, though no sibling is named explicitly.

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 'currently shown on screen' implies the applicable situation (popups blocking the view), but there is no explicit when-to-use, no exclusion, and no reference to alternatives such as show_popup or get_focused_screen.

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