AI CLI Background Music Player - Plays work music in loop and done music when finished

"AI fatigue is real." - Siddhant Khare

mythril-agent-bgm is a cross-platform CLI tool that adds audio feedback to AI-assisted coding sessions. It plays looped work music while the agent is active, plays a done cue when work finishes, and stops automatically at session end.

Why

AI coding sessions are productive but mentally expensive. This tool helps by turning invisible state changes into simple audio cues:

• work music loops when the agent is actively working
• done cue plays when a task finishes
• playback stops automatically when the session ends

This reduces constant status-checking and makes long sessions less draining.

Install

pip install mythril-agent-bgm

# Upgrade
pip install -U mythril-agent-bgm

This installs the bgm command.

Quick Start

On first run, any bgm command initializes your user config directory with starter files.

1. bgm setup - install hooks/plugins for detected AI tools
2. bgm select - choose a BGM profile (default or your custom profile)
3. bgm enable - enable automatic BGM behavior

Optional quick check:

bgm play work 0
bgm stop

Supported Integrations

• Claude Code
• Cursor Agent
• Gemini CLI
• OpenCode (plugin-based)

bgm setup only configures tools detected on your machine.

Config Paths

• macOS/Linux: ~/.config/mythril-agent-bgm/
• Windows: %APPDATA%\mythril-agent-bgm\

Important files:

• config.json - custom BGM profiles
• selection.json - selected profile and enable/disable state
• sounds/ - user .mp3 files (flat directory, no subdirectories)
• bgm_player.pid - daemon process ID
• bgm_player.log - daemon log file

Customize Audio

1. Copy .mp3 files into your user sounds/ directory.
2. Edit your user config.json:

{
  "my_collection": {
    "work": ["my_song.mp3", "another.mp3"],
    "done": ["done.mp3"],
    "notification": ["ping.mp3"]
  }
}

3. Run bgm select and choose my_collection.

Notes:

• profile names are arbitrary (my_collection is only an example)
• user audio files override built-in files when names are the same
• only bare filenames are supported (no nested paths)

Common Commands

bgm play work 0          # Loop work music indefinitely
bgm play work 3          # Play work music 3 times
bgm play done            # Play done music once
bgm play notification    # Play notification sound
bgm stop                 # Stop current playback daemon
bgm toggle               # Toggle play/stop
bgm select               # Choose profile
bgm setup                # Configure integrations
bgm cleanup              # Remove integration changes
bgm enable               # Enable automatic BGM
bgm disable              # Disable automatic BGM

Troubleshooting

# Verify pygame is installed
pip show pygame

# Stop active playback
bgm stop

If issues continue, inspect files in your config directory:

• bgm_player.log
• bgm_player.pid

Uninstall

pip uninstall mythril-agent-bgm

Optional: remove your user config directory manually.
