babel-zellij

Zellij plugin for babel — live agent session status in your terminal multiplexer.

What it does

Renders a status bar pane inside zellij showing the state of all tracked agent sessions (Claude, Codex, Gemini, etc.) managed by babel. Updates are push-based via zellij pipe IPC — no polling.

Architecture

babel daemon ──paint stream──→ babel zellij-bridge ──zellij pipe──→ this plugin

1. babel daemon tracks agent sessions across terminal panes
2. babel zellij-bridge subscribes to the daemon's paint stream
3. Bridge pipes JSON state to this plugin via zellij pipe --name babel
4. Plugin renders the status bar with live activity indicators

Setup

Build

Requires rust-wasm package (Arch: pacman -S rust-wasm):

    plugin location="file:/path/to/target/wasm32-wasi/release/babel-zellij.wasm"
}

Or add to your zellij layout as a background command pane.
