Assignment for {owner} is no longer active

Error message

Assignment for {owner} is no longer active

What it means

The cwd-lease resolver checks the task recorded in a teammate's assignment: it must exist, be in_progress or completed, and still be owned by that owner. If the task was reassigned, reset to pending, or the assignment references a stale/deleted task, the lease is dead and this ValueError propagates (surfaces to the agent as an Error: message from _agent_cwd).

Solutions

1. Restart the session so assignments rebuild from current task state (the stale in-memory lease is dropped).
2. Avoid resetting/reassigning tasks that other sessions actively own; complete or release them first.
3. If state is inconsistent, remove the stale assignment by restarting or releasing via release_completed_assignment().

def assignment_alive(assignment: dict) -> bool:
    try:
        task = load_task(str(assignment["task_id"]))
    except Exception:
        return False
    return task.status in {"in_progress", "completed"} and task.owner is not None

try:
    cwd = _agent_cwd_for(owner)
except ValueError as e:
    if "no longer active" in str(e):
        # session state is stale: restart or re-claim the task; do not retry blindly
        raise

When it happens

Trigger: Owner's assigned task got its status flipped to pending or owner changed while the agent held the lease; task file deleted; assignment dict references a task_id that no longer loads; concurrent admin action resetting tasks mid-session.

Common situations: Two sessions for the same owner; a task reset/reassign tool used while an agent was mid-turn; leftover in-memory assignments after the tasks directory was wiped.
