Orchestrator/subagent coordination workflow for tasks that can be split into clear disjoint work. Use when the user invokes $subagents, says "use subagents", "spawn agents", "parallelize this", "delegate this", "split this across agents", or asks for coordinated multi-agent work. Prefer subagents for harder tasks, broad research, multi-file changes, independent reviews, or separable implementation lanes. Skip subagents when the task is simple, the harness does not support them, or safe disjoint work cannot be identified.
