Castor-o7/muster

The purpose of Muster is to provide you, a very busy person, with the ability to muster some agent teams into a dynamic development environment. What do I mean by this? Agentic parallelism is rife with token waste and context creep trouble. If you or a loved one has to interact with agents in VMs, or across devices on a single local network; then you've probably experienced how quickly this can become a complicated scenario. Cue muster! Muster the troops by setting up a main 'watchman' agent in a directory of your choice and see the watchman organize the rest of your agent teams, coordinating securely to tackle given design roadmaps. Have you already taken the time to design a thorough roadmap for your catapp, and now you need to go grocery shopping? Great! Give an agent or two your roadmap, using the CLI of your choice; setup a watchman to monitor and organize workflow, and then BAM! You can go take your dog for a walk and come back to some completed stories!
Muster lets Claude Code sessions find each other and talk, on one machine or across
your network. A message wakes an idle session by itself, even one nobody has typed to
yet, and it does this without --dangerously-load-development-channels.
It's built for teams of agents working through a roadmap together: a session can ask
another for help, hand off work, or report that a story is ready for review, while you
get on with something else.
Live, with no flag. An ordinary Claude Code hook waits for mail and wakes the
session when a message arrives. It uses no model turns while waiting.
Across machines. One daemon serves every paired machine over TLS, with its
certificate pinned and a revocable token for each machine.
Durable. With Postgres, messages and the roster survive a daemon restart. Messages
to a session that has ended are eventually deleted with it.
Built on myko, in Rust. New code is Rust. Codex is
supported through the same shim, and Pi, opencode and Prime Agent have plugins inherited
from Marshal that aren't being actively developed.
Muster is for one operator's own machines, on a private network or over Tailscale or
WireGuard: pair only machines you trust. SECURITY.md describes its security
model.
See the roadmap for where this is heading and
the board for how the teams work together. Muster carries the messages and
doesn't track work; Rally is the separate ledger of
each team's progress.
Muster is a fork of Marshal by
ignition-is-go, used under its MIT OR Apache-2.0 licence, and it can run side by side with
Marshal: it has its own binaries (muster-shim, muster-daemon), ports (6255, 6256 and 6258),
MUSTER variables and ~/.config/muster. Issue and PR numbers in older comments and
docs (#139 and so on) refer to the Marshal repository.
## Install
Install the binaries, run the daemon, then wire the harnesses you use.
