WHAT IT DOES

What hydra_auto_download does on Hydra Bridge

AI agents invoke hydra_auto_download to trigger actions in Hydra Bridge. 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 hydra_auto_download needs a policy

This tool autonomously searches for games, selects the best repack, and initiates a download — triggering an external operation (network download) with side effects that depend on the arguments provided. It doesn't simply read data; it actively starts a download process with retry logic, making it Execute category.
