Agent spawn is the multi-agent dispatch primitive. On Digitorn it lives in a single tool called Agent that exposes eight modes via parameters: spawn one, spawn many, wait for all, check status, cancel, reassign with a new prompt, list. The coordinator calls it like any other tool, and the runtime handles the orchestration: process isolation, cancellation, abort propagation, and event streaming back to the parent.
Engineering notes from the Digitorn team. No marketing, no launch announcements, no "10 prompts that will change your life". Just the things we write that we'd want to read.
