Fahh monitors your VS Code tasks and terminal sessions. When something exits with a non-zero code, it plays Fahhh.mp3 so you know immediately — even if you're looking away from the screen.
What it catches
Source
How
Tasks (build, test, custom)
onDidEndTaskProcess — fires when any task process exits
Shell commands
onDidEndTerminalShellExecution — fires per command in the integrated terminal
Terminal crashes
onDidCloseTerminal — fires when a terminal session closes with a non-zero exit status
Setup
Install from the Marketplace or from a .vsix file. That's it — Fahh activates on startup and runs silently in the background until something fails.
No configuration needed. No keybindings. No commands.
Platform notes
Windows — uses System.Windows.Media.MediaPlayer via PowerShell (built-in, no extra installs).
macOS — uses afplay.
Linux — uses ffplay (install via sudo apt install ffmpeg or equivalent).
Packaging & publishing
Build the .vsix
npm install
npx @vscode/vsce package
This produces fahh-1.0.0.vsix. Install it locally through Extensions → ⋯ → Install from VSIX.
