Tip: Use Nested Subagents to Offload Noise — Each Layer Gets a Clean Window

claudefa.st·medium signal

With v2.1.172, the win from nested subagents is context hygiene: delegate noisy, token-heavy tasks (large file reads, log scraping, repetitive verification) to a deeper subagent that starts with a fresh window, so the parent's context stays clean. Because the offload-the-noise pattern works identically at layer 4 and layer 1, structure deep work as a tree rather than cramming everything into one conversation — but watch the five-level hard cap.
