## Why browser_storage_clear is rated Critical

Clearing all items in storage is an irreversible bulk deletion operation. All data stored in localStorage (which persists across sessions) or sessionStorage would be permanently removed, with no way to recover it without a prior backup. This is a destructive action with potentially high blast radius as it could wipe authentication tokens, user preferences, cached data, and application state.

From the tool's own definition: "Clear all items in localStorage or sessionStorage"

Risk signals: Bulk/mass operation — affects multiple targets
