What clear_completed_tasks does on VaultAssist
AI agents call clear_completed_tasks to permanently remove resources in VaultAssist, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why clear_completed_tasks is rated Critical
While the description says tasks are 'marked as hidden' rather than permanently deleted, 'clearing' completed tasks is a bulk irreversible operation that removes visibility of all completed tasks at once. The word 'clear' combined with bulk scope (all completed tasks) and lack of any undo mechanism described makes this effectively destructive.

clear_completed_tasks is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
