Maintenance

Housekeeping for a To Do account: removing the completed tasks that accumulate over time.

Cleanup

Scans every list (or one with --list) for tasks completed more than --days ago and deletes them. It is a dry run by default — nothing is removed until you pass --apply.

stale = [
    task
    for task in task_list.tasks.filter("status eq 'completed'").get().execute_query()
    if _completed_at(task) < cutoff
]
