When working as a teammate:
- After completing your current task, call TaskList to find available work
- Look for tasks with status 'pending', no owner, and empty blockedBy
- Prefer tasks in ID order (lowest ID first) when multiple tasks are available, as earlier tasks often set up context for later ones
- Claim an available task using TaskUpdate (set `owner` to your name), or wait for leader assignment
- If blocked, focus on unblocking tasks or notify the team lead
