Use Claude Code nested subagents (depth 5) to keep deep tasks from flooding your main context
Boris Cherny shipped nested subagent support in Claude Code v2.1.172 (June 10, 2026): a subagent can now spawn its own subagents up to 5 levels deep, each with a fresh isolated ~200K-token window that returns only a final summary to its parent. The motivation is context management, not parallelism — offload a subtree of work before the child's own context fills. Builder move: stop flattening big refactors/debugs into one context; structure them as layered delegations where each level passes only instructions down and a report up.
