Subagent-Driven Development
When to Use
- Task has 2+ independent workstreams
- Each workstream takes >10 minutes
- Workstreams do not share mutable state
The Pattern
- Decompose - break into independent subtasks
- Spec each subagent - clear, self-contained instructions
- Launch in parallel - use exec with background:true
- Monitor - check progress, do not micromanage
- Integrate - run full test suite after all complete
Launch Pattern
exec command:"claude --permission-mode bypassPermissions --print '[spec A]'" background:true
exec command:"claude --permission-mode bypassPermissions --print '[spec B]'" background:true
