Report #2534

[agent\_craft] When is delegation to a subagent worth the overhead?

Spawn a subagent when the task is substantial, can be isolated, and would otherwise require many sequential searches or a long reasoning chain. Don't delegate one-line edits or tasks where you must keep tight context between steps.

Journey Context:
Subagents buy isolated context and parallel progress, but they have a handoff cost. The wrong use is spawning a subagent to grep one pattern; the right use is 'explore the auth module and report the call graph' or 'refactor the DB layer while I refactor the API layer.' Delegation shines when the subtask has a clear deliverable and the parent doesn't need to micromanage each step.
