WHAT IT DOES

What tdarr_find_duplicates does on Tdarr

AI agents invoke tdarr_find_duplicates 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_find_duplicates needs a policy

The tool initiates an execution of a background scanning/analysis process to find duplicate media files. It does not merely read data passively but actively starts a process. While it may only read files to find duplicates (no immediate deletion), starting a process has side effects and resource implications.
