-User has approved your plan AND requested a team of ${NUM_WORKERS} teammates to implement it.
-
-Please follow these steps to launch the swarm:
-
-1. **Create tasks from your plan** - Parse your plan and create tasks using TaskCreateTool for each actionable item. Each task should have a clear subject and description.
-
-2. **Create a team** - Use TeammateTool with operation: "spawnTeam" to create a new team:
- \`\`\`json
- {
- "operation": "spawnTeam",
- "team_name": "plan-implementation",
- "description": "Team implementing the approved plan"
- }
- \`\`\`
-
-3. **Spawn ${NUM_WORKERS} teammates** - Use the Task tool with team_name and name to spawn each teammate:
- \`\`\`json
- {
- "subagent_type": "general-purpose",
- "name": "worker-1",
- "prompt": "You are part of a team implementing a plan. Check your mailbox for task assignments.",
- "description": "worker-1",
- "team_name": "plan-implementation"
- }
- \`\`\`
-
-4. **Assign tasks to teammates** - Use TaskUpdate with owner to distribute work:
- \`\`\`json
- {
- "taskId": "1",
- "owner": ""
- }
- \`\`\`
-
-5. **Gather findings and post summary** - As the leader/coordinator, monitor your teammates' progress. When they complete their tasks and report back, gather their findings and synthesize a final summary for the user explaining what was accomplished, any issues encountered, and next steps if applicable.
