What browser_scroll does on Termux Browser Pilot
AI agents invoke browser_scroll to trigger actions in Termux Browser Pilot. 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.
Why browser_scroll is rated High
Scrolling is a browser action that executes a UI interaction within the automated browser. While it has minimal direct harm potential, it is an Execute-category action because it triggers an external operation (browser scroll event) whose effect depends on arguments (scroll position/direction). It cannot be classified as Read since it causes a side effect in the browser state.
From the tool's definition 'Scroll the page' — triggers a browser interaction/action in a real browser automation context
