WHAT IT DOES

What browser_tab_next does on Termux Browser Pilot

AI agents invoke browser_tab_next 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.

RISK

Why browser_tab_next is rated High

This tool triggers a browser action (tab switching) in an automated browser session running on the device. It doesn't read data, write/modify data, or destroy anything, but it does execute a browser UI action. The blast radius is low since switching tabs is a navigational operation with minimal direct harm, though it could be chained with other actions in an automation sequence.

browser_tab_next Rate-limited

browser_tab_next stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
