WHAT IT DOES

What fw_play_album does on Crow

AI agents invoke fw_play_album to trigger actions in Crow. 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.

RISK

Why fw_play_album is rated High

This tool triggers an external hardware operation — playing audio through a paired glasses speaker device. It initiates a real-world action (audio playback) on an external device, which classifies it as Execute. Misuse could result in unwanted audio output on a user's device, hence medium severity.
