Delegate a bounded coding task to a second, background `agy -p` implementer run — on a different model than the one orchestrating — then review its diff and land it yourself. Use whenever the user wants to hand off implementation while staying the reviewer, wants a cheap/fast model for a mechanical task while a stronger model plans or reviews, or explicitly asks to "delegate", "run this on another model", or "spin off a background agy run". Native to Antigravity/agy — no external CLI required. DO NOT USE for tasks small enough to just do inline.
