WHAT IT DOES

What tdarr_item_proc_end does on Tdarr

AI agents invoke tdarr_item_proc_end to trigger actions in Tdarr. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why tdarr_item_proc_end needs a policy

This tool triggers an external operation in the Tdarr distributed transcoding system — specifically signaling completion of item processing to a node. It causes a state change in the system (marking an item as processed), which is an external operation with side effects beyond simple data writes. It's not destructive or financial, but it executes a workflow state transition in the transcoding pipeline.
