Saggar

Run four coding agents at once and an ordinary terminal shows four tabs, none of which say which one is stuck at a permission prompt. Saggar labels every session as working, idle, needs you, finished, or failed, and keeps each one attached to its project, branch, and worktree. Sessions waiting on a decision collect into a single queue you step through with a keyboard shortcut.

A companion app extends that to a phone: you can read a session, answer its prompt, interrupt a runaway, or type into it while away from the desk. Pairing goes through a QR code and a Marginal Utility account, and the Mac dials out to a relay rather than opening a port. It needs Apple silicon with macOS 26 Tahoe or later, and installation comes in two forms, Homebrew or a direct download.
