README

projmux

A tmux-native workspace for multi-agent AI development.
Managed Claude Code, Codex, and Antigravity panes with hook-driven attention and agent-aware session resume.

npm install -g projmux
projmux shell

projmux AI session resume, agent permission, and grouped notification workflow
Resume an existing AI session, keep working in another project, then return through grouped notifications when the agent needs approval.

Why

Six tmux windows. Each one is running Claude Code, Codex, or Antigravity on a different repo. Three are idle. One is waiting on a permission prompt. One crashed an hour ago and you have no idea which.

projmux manages Claude Code, Codex, and Antigravity hook integrations, including Antigravity's hook/statusline wiring, shows live per-pane state in the tmux status bar, and lets one keystroke take you to the pane that actually needs you. It also remembers each agent's resume id, so after a reboot every pane comes back as the *same* conversation — not a fresh one.
