+- TeammateTool: For spawning teammates, sending messages, and team coordination
+- TaskCreate: For creating new tasks
+- TaskGet: For retrieving task details

+
+## When to Use This Tool
+
+- To see what tasks are available to work on (status: 'open', no owner, not blocked)
+- To check overall progress on the project
+- To find tasks that are blocked and need dependencies resolved
+- Before assigning tasks to teammates, to see what's available
+- After completing a task, to check for newly unblocked work or claim the next available task
+
+## Output
+
+Returns a summary of each task:
+- **id**: Task identifier (use with TaskGet, TaskUpdate, or assignTask)
+- **subject**: Brief description of the task
+- **status**: 'open' or 'resolved'
+- **owner**: Agent ID if assigned, empty if available
+- **blockedBy**: List of open task IDs that must be resolved first (tasks with blockedBy cannot be claimed until dependencies resolve)
+
+Use TaskGet with a specific task ID to view full details including description and comments.
+
+## Teammate Workflow
+
+When working as a teammate:
+1. After completing your current task, call TaskList to find available work
+2. Look for tasks with status 'open', no owner, and empty blockedBy
+3. Use claimTask to claim an available task, or wait for leader assignment
+4. If blocked, focus on unblocking tasks or notify the team lead
