## Why browser_select_option is rated High

Selecting a dropdown option is a browser action that modifies UI state and can trigger downstream effects such as form field changes, dynamic content loading, or even form submission. It falls under Execute as it performs an external browser operation whose impact depends on the context/arguments.

From the tool's own definition: "'Select an option in a dropdown' — triggers a browser interaction that changes the state of a UI element, which may cause side effects depending on the application (form submissions, navigation, data changes)."

## Use case

AI agents invoke browser_select_option to trigger actions in A11y Agent Skills. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
