Segfault Lullaby

Small deaths sigh; session endings lullaby.

Quiet audio cues inside VS Code / Cursor: when a command in the integrated terminal fails, you get a short sigh. When a coding session ends (via command or hook signal), you get a longer closing lullaby.

Install

From the Marketplace (once published)

1. Open Extensions (Ctrl+Shift+X / Cmd+Shift+X)
2. Search for Segfault Lullaby (publisher Sciad)
3. Install → Reload Window if prompted

From a VSIX (sideload)

1. Download segfault-lullaby-*.vsix from Releases or build locally (npm run package)
2. Command Palette → Extensions: Install from VSIX…
3. Developer: Reload Window

Try it

1. Ensure Terminal › Integrated: Shell Integration is enabled
   (terminal.integrated.shellIntegration.enabled → true)
2. In the integrated terminal:

true      # silent
false     # short sigh

3. Command Palette → Segfault Lullaby: Play Closing Lullaby (or Play Test Sigh)
4. Too loud? Segfault Lullaby: Toggle Mute, or set segfaultLullaby.muted

You need a system audio path (ffplay / paplay / aplay / afplay, or Windows powershell Media.SoundPlayer — works from WSL via wslpath).
