A Pi extension that adds a persistent heads-up display below the editor (above Pi’s built-in footer).

Full-quality MP4: https://raw.githubusercontent.com/tmustier/pi-session-hud/main/assets/demo.mp4

HUD placement (below editor/input, above footer):

(Hosted on GitHub so npm users see the media in README, but npm install stays small.)

• Activity state (idle / running / tool / error / stale)
• Session name (or cwd) and first user message fallback
• Git branch + worktree marker (⎇ name current/total when multiple) + diff stats
• Context usage (% + tokens)
• Current model (+ thinking level)

pi install npm:@tmustier/pi-session-hud

pi install git:github.com/tmustier/pi-session-hud

Symlink into Pi’s auto-discovered extensions directory:

ln -s ~/pi-session-hud/pi-session-hud.ts ~/.pi/agent/extensions/

Or add to ~/.pi/agent/settings.json:

{
  "extensions": ["~/pi-session-hud/pi-session-hud.ts"]
}

In Pi:

• Toggle HUD: /hud
• Aliases: /status, /header

• Uses ctx.ui.setWidget(..., { placement: "belowEditor" }) so it’s not the footer and not a header.
• Git stats are refreshed every ~10s via git diff --stat HEAD + git status --porcelain.
