AI agents call browser_events_clear 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.
Clearing all captured DOM events is an irreversible action — once cleared, the event history is permanently lost and cannot be recovered. This matches the Destructive category (irreversibly deletes/overwrites data). Severity is medium since it affects in-session event data rather than persistent user data, but misuse could destroy important captured interaction records.
