Practical fit
Subagents are useful when work can be divided into clearly owned investigations or when a separate reviewer should remain independent from the maker. Parallelism only helps when the outputs can be reconciled without creating contradictory edits.
For a small task, delegation adds coordination cost and makes the final decision less legible. Use one agent when the work is tightly coupled or when every subtask needs the same context.
How to evaluate it
Example decision
During a migration, one subagent can inventory deprecated imports while another reads the official upgrade guide. A single owner then combines those findings into the implementation plan instead of letting both agents edit the same files.
