WHAT IT DOES

What browser_storage_remove does on Termux Browser Pilot

AI agents call browser_storage_remove to permanently remove resources in Termux Browser Pilot, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why browser_storage_remove is rated Critical

This tool irreversibly deletes a specific key from browser storage (localStorage or sessionStorage). While scoped to browser storage rather than files or databases, removal of storage keys can destroy session state, authentication tokens, or application data that may be difficult or impossible to recover, making it Destructive rather than merely Write.

browser_storage_remove Hidden

browser_storage_remove is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
