Install

Public (binary)

Use this for users on production machines where you don't want to expose source.

curl -fsSL https://raw.githubusercontent.com/getcompanion-ai/co-mono/main/public-install.sh | bash

Install everything and keep it always-on (recommended for new devices):

curl -fsSL https://raw.githubusercontent.com/getcompanion-ai/co-mono/main/public-install.sh | bash -s -- --daemon --start

This installer:

• Downloads the latest release (or falls back to source when needed),
• writes ~/.local/bin/co-mono launcher,
• populates ~/.co-mono/agent/settings.json with package list,
• installs packages (if npm is available),
• and can install a user systemd service for co-mono daemon so it stays alive.

Preinstalled package sources are:

[
  "npm:@e9n/pi-channels",
  "npm:pi-memory-md",
  "npm:pi-teams"
]

If npm is available, it also installs these packages during install.

If no release asset is found, the installer falls back to source.

  curl -fsSL https://raw.githubusercontent.com/getcompanion-ai/co-mono/main/public-install.sh | bash -s -- --daemon --start

public-install.sh options:

curl -fsSL https://raw.githubusercontent.com/getcompanion-ai/co-mono/main/public-install.sh | bash -s -- --help

Local (source)

git clone https://github.com/getcompanion-ai/co-mono.git
cd co-mono
./install.sh

Run:

./co-mono

Run in background with extensions active:

./co-mono daemon

For a user systemd setup, create ~/.config/systemd/user/co-mono.service with:

[Unit]
Description=co-mono
After=network-online.target

[Service]
Type=simple
Environment=PI_CODING_AGENT_DIR=%h/.co-mono/agent
Environment=CO_MONO_AGENT_DIR=%h/.co-mono/agent
ExecStart=/absolute/path/to/repo/co-mono daemon
Restart=always
RestartSec=5

[Install]
WantedBy=default.target

Then enable:

systemctl --user daemon-reload
systemctl --user enable --now co-mono

Optional:

npm run build   # build all packages
npm run check   # lint/format/typecheck

Development

npm install          # Install all dependencies
npm run build        # Build all packages
npm run check        # Lint, format, and type check
./test.sh            # Run tests (skips LLM-dependent tests without API keys)
./pi-test.sh         # Run pi from sources (must be run from repo root)

Note: npm run check requires npm run build to be run first. The web-ui package uses tsc which needs compiled .d.ts files from dependencies.
