Use when the user asks to use Jev or Kev, when a task needs bulk classification, yes/no filtering, or scoring of many items, or when browser work is repetitive or high-volume (many searches, collecting results across pages). Jev is TypeSafe's fast decision model and drives the jevx CLI and the Agents Chrome on this Machine. For one-off browsing, use your usual browser tools unless the user asks for Jev.
