Agent Manager

Claude Code, Codex, OpenCode, Grok, Gemini CLI, Antigravity CLI, Pi, Command Code, Hermes Agent, Muse Code, and Oh My Pi run side by side. Each tool runs in its own persistent tmux session.

agent-manager is a thin layer over the CLIs you already have. Each session launches your own installed tool as-is: your login, your subscription, your config files, your MCP servers, and every feature the tool ships all carry over, exactly as they behave in a plain terminal.

Instead of hunting through terminal tabs to see which agent is done and which is stuck, every session shows up in one list with live status, grouped into a project tree you can fold and reorder. You answer any of them without attaching: space sends a prompt straight into a session's pane, or spawns a new agent in the selected group. A dead session revives on its own conversation with v. And ctrl+r opens a full-file diff of what an agent changed, syntax-highlighted, where the comments you leave on lines go back to the agent's pane as one review prompt when you press C.

Press f on a session to continue its conversation in a separate named fork.

The mouse works across the whole manager. The wheel moves the cursor, a click on a session focuses it, and a click on its row or the mouse back button brings you back. Drag a row by its handle (⠿ in Advanced, = in Compatible) to reorder it or move it into another group, and the […] at the end of every row opens its actions. The divider between the list and the preview drags, and while any message is left, a click on messages in the key legend opens it. In a focused pane a drag selects and copies text, and a click on a link opens it in your browser. Settings has a mouse toggle for terminals where you want native selection back. Settings → symbols switches between Advanced geometric marks (the default) and Compatible ASCII marks, with a live preview.

The tools you use alongside agents live in the same list: T opens a shell under the selected agent, or in the selected group, for builds, Git, and one-off commands. An agent can spawn another, send it a message, and wait until it is done: every MCP-capable session carries those tools on launch.

Save named instructions in Settings and reuse them from the New Session form, the quick prompt, a focused session, spawn --saved, send --saved, or create_session. See Saved prompts.

Supported tools

Status detection supports Claude Code, OpenCode, Codex, Grok Build, Gemini CLI, Antigravity CLI, Pi, Command Code, Hermes Agent, Muse Code, and Oh My Pi. Each one's launch, revive, fork, and status rules ship in the binary (Hermes, Antigravity, and Oh My Pi have no fork), so an upgrade brings the current version of all of them (see Configuration). A CLI that is not on the list is a feature request.

Install

Runs on macOS and Linux, natively on Windows with psmux, and inside WSL2.

Homebrew (macOS / Linux)

brew install agent-manager

Installs tmux with it if missing, and Homebrew runs on git, so both dependencies are covered. This is the homebrew-core formula, which builds from source. For the prebuilt binary, brew install --cask yoanwai/tap/agent-manager.

Install script (macOS / Linux)

curl -fsSL https://raw.githubusercontent.com/YoanWai/agent-manager/main/install.sh | sh

Downloads the latest release for your platform, verifies it against the published checksums, and installs it to ~/.local/bin. Then it checks for tmux 3.1+ and git and offers to install whichever is missing through the package manager it finds (Homebrew, apt, dnf, pacman, zypper, or apk), printing the exact command when you decline. Set AGENT_MANAGER_INSTALL_DIR for another directory, AGENT_MANAGER_VERSION to pin a version, and AGENT_MANAGER_INSTALL_DEPS=1 to answer the dependency prompt up front (=0 to skip it).

Install script (Windows)

irm https://raw.githubusercontent.com/YoanWai/agent-manager/main/install.ps1 | iex

Installs the latest release to %LOCALAPPDATA%\Programs\agent-manager, adds it to your user Path, and names the install command for psmux, git, or PowerShell 7 when one is missing.

Arch Linux, mise, go install, prebuilt binaries, Windows (native and WSL2), dependencies, and updating: docs/install.md.

Usage

agent-manager

Sessions run inside tmux (am_* namespace), so they survive the manager quitting. Inside a session, Ctrl+Q detaches back to the manager when your terminal and tmux leave it available; Ctrl+\ is an alternate under the same rule. Ctrl+R opens the session's diff review and F3 opens its directory in your editor; the keybindings row in Settings (s) moves any of them, or hands one back to the agent, and moves or turns off any action of the manager's own list, with esc and ctrl+c staying as they are (see Key bindings). In a full-screen attach, the session footer also shows an inner tmux prefix followed by d when configured. When nested inside another tmux, send the inner prefix shown in the footer, then press d. If both tmux servers use the same prefix, invoke the outer tmux's send-prefix binding; if the outer tmux otherwise captures the inner prefix, configure it to forward that key. agent-manager --version prints the version.

Agent sessions live on a private tmux server named agentmgr, so they never mix with the tmux you run yourself and a kill-server on your own socket leaves them alone. To reach one from a plain shell, name that server: tmux -L agentmgr ls, then tmux -L agentmgr attach -t am_<id>.

The full reference, every key, quick prompt mode, killing and reviving, diff review, groups, status detection, stats, and themes, lives in docs/usage.md. Tell your agent what you want to review in Agent Manager, and your agent will set it up for you to view in the review panel. You can also tell your agent to manage sessions and terminals in Agent Manager. The short version:

A session can spawn into its own git worktree (<repo>-worktrees/<name>, branch am/<name>), toggled on the n form, with ctrl+t in quick prompt mode, or by default in Settings.

A session can start on a model, reasoning effort and profile of its own, picked on the n form, with ctrl+l, ctrl+x and ctrl+y in quick prompt mode, or with spawn --model --effort --profile. The lists come from each CLI at runtime, so a new model shows up the day the CLI ships it, and restart, revive and fork keep the choice (see Model, effort and profile).

Configuration (Settings, the editor o opens, and the key tables) is in docs/configuration.md.

Development

go run .
env -u TMUX TMUX_TMPDIR=/tmp/amtest go test ./...   # end-to-end tests drive a real tmux server
