leghorn 0.2

Full-screen live view of every Claude Code session, its git state, and your GitHub CI

leghorn

A full-screen live dashboard you leave open on a second monitor while many Claude Code sessions work: every live session joined to its worktree and real git state, your GitHub CI and open PRs with failures pinned until they go green, and a commit feed across every repo, newest first.

Sessions that share a working tree are marked contested (◉) — two sessions in one checkout silently destroy each other's uncommitted work, and seeing it happen is the first step to not doing it. The GitHub pane ranks by what it costs to ignore: running first, then red (a failure must not scroll away), then stuck-in-queue, then everything else by freshness.

Two files, stdlib only, Python 3.9+. macOS and Linux (curses). Read-only by construction: it runs gh, read-only git plumbing, and (if present) claudectl, and never writes to a tree, a registry or a session. Every data source is optional — missing pieces degrade to a labelled gap, never an error.

Install

Homebrew (macOS and Linux):

brew install gmhoward9289-ops/tap/leghorn

npm:

npm install -g leghorn

pipx / pip:

pipx install leghorn

Debian and Ubuntu, from the signed apt repo — this also gets you apt upgrade:

curl -fsSL https://gmhoward9289-ops.github.io/leghorn/leghorn-archive-keyring.asc | sudo gpg --dearmor -o /usr/share/keyrings/leghorn-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/leghorn-archive-keyring.gpg] https://gmhoward9289-ops.github.io/leghorn stable main" | sudo tee /etc/apt/sources.list.d/leghorn.list
sudo apt update
sudo apt install leghorn

Or grab leghorn_<version>_all.deb from the latest release and sudo apt install ./leghorn_<version>_all.deb.

What it needs

• git — for the per-tree state and the commit feed.
• gh (authenticated) — for the GITHUB pane. Unauthenticated, the pane says "cannot see github" rather than pretending nothing is happening; an empty feed and a feed that cannot see are different facts.
• claudectl (optional) — session status and context columns. Without it you still get names, trees, branches and git state.

Clones are discovered under ~/GitHub (override: LEGHORN_ROOT).

Usage

leghorn                  # three panes, refreshing every 5s
leghorn -i 2             # ...every 2s
leghorn --no-github      # hide the GitHub pane (no gh calls at all)
leghorn --no-commits     # hide the commit feed
leghorn --github-interval 120   # slower gh sweeps

Keys: q quit · r refresh (including a gh sweep) · s/f cycle sort/filter · tab cycle panes · j/k move · enter detail · ? help — which explains what each screen and symbol means, not just the keys.

The data layer is also a command of its own:

python3 -m ccboard            # one table of sessions, for a hook or a pipe
python3 -m ccboard --github   # the CI/PR feed as plain text
python3 -m ccboard --json     # records, for piping somewhere else

Name

The Leghorn is the chicken breed that spots everything first and is never quiet about it.
