Dispatching Parallel Agents

Core principle: dispatch one agent per independent problem domain. Let them work concurrently.

⚠️ Cost awareness: Parallel agents consume significantly more tokens than sequential approaches (often 10-15× more). Each agent loads its own full context. Use parallel dispatch only when the speed gain justifies the cost.

When to Use

• 3+ test files failing with different root causes
• Multiple subsystems broken independently
• Each problem can be understood without context from others
• No shared state between investigations

Prefer Sequential When

• Failures may be related (fixing one might fix others)
• Full system context is needed
• Agents would edit the same files
