maestro-tui 0.1.2

A terminal-native multi-agent command center

maestro

A terminal-native multi-agent command center. Spawns AI/CLI agents in real PTYs and shows them in switchable panes with a session timeline — all inside one TUI.

Install

Maestro is a Python CLI (needs Python 3.11+ and a claude on your PATH). Install it on any device with pipx so it lands in its own isolated venv with the maestro command on your PATH:

pipx install "git+https://github.com/jmbmunda/maestro.git"

Or run it once without installing, using uv:

uvx --from git+https://github.com/jmbmunda/maestro.git maestro

Update later with pipx upgrade maestro. Pin a release with ...@v0.1.0.

From source (development)

git clone https://github.com/jmbmunda/maestro.git && cd maestro
python3 -m venv .venv && source .venv/bin/activate
pip install -e .

Run

maestro

Keys

Each pane is a real terminal (full ANSI: colors, cursor, alt-screen), so claude, vim, htop etc. render correctly. Maestro has two modes:

OUTSIDE (default — manage panes):

• Ctrl+S — spawn a claude agent in a new pane
• Ctrl+Shift+S — spawn a $SHELL agent (terminal-dependent; see note)
• Ctrl+W — dismiss the focused pane (confirms first if it's still running)
• r — rename the focused pane (blank resets to the default pane-N · claude)
• b — broadcast one prompt to multiple panes at once (pick targets, type, Enter)
• a — quick agents: launch a pre-seeded role, or create/edit/delete templates
• Ctrl+J / Ctrl+K — focus next / previous pane
• Ctrl+L — cycle layout: split → grid → focused
• Ctrl+B — toggle the sessions status panel
• Ctrl+A — toggle the agents panel (off by default)
• Ctrl+T — toggle the timeline
• / — open the skills launcher (pick a skill → injects /name into the focused pane)
• Enter — step INSIDE the focused pane to interact with it
• q — quit (also Ctrl+Q, where the terminal doesn't grab it — the VSCode integrated terminal does)

INSIDE (drive one agent): every keystroke goes straight to that pane's terminal — arrows, Esc, Tab, Shift+Tab (cycle Claude modes), Option+Enter (newline), Option+←/→ (word motion), Ctrl-C, everything. The one reserved key is Ctrl+], which steps back OUTSIDE.

Heads-up: Ctrl+] is reliable everywhere (terminals send it as a single byte, 0x1d). Ctrl+Esc also works as a fallback, but only in terminals that transmit it distinctly (kitty keyboard protocol / modifyOtherKeys=2). The footer reflects the mode — while INSIDE it shows just Ctrl+] Exit pane; OUTSIDE it shows the command list.

Scroll back through a pane's history — every pane has a real scrollbar: drag the thumb, click the trough to page, or mouse-wheel over the pane (works INSIDE or OUTSIDE, including finished panes). While OUTSIDE, PageUp/PageDown page the focused pane. The border title shows ⇡N (scrolled) while you're above the live view; the pane keeps following new output while parked at the bottom and stays put once you scroll up — typing INSIDE snaps you back to the live bottom. Up to ~2000 lines are kept per pane.

Click a pane to focus + interact in one step — clicking auto-enters that pane, no separate Enter needed. Clicking a different pane while INSIDE another stays INSIDE the new one. Clicking a finished pane drops you back OUTSIDE. In focused layout, click a row in the panes strip to switch.

(Keyboard nav Ctrl+J/Ctrl+K still moves focus without auto-entering, so you can chain commands like spawn → navigate → spawn → … without stepping in.) The background is transparent, so maestro inherits your terminal's wallpaper/theme.

Quick agents

Press a (OUTSIDE) for one-click specialized agents. A quick agent is a template — a name + a starting prompt + an optional skill — that spawns a claude pane, names it, injects the skill and prompt, and drops you inside. Ships with built-ins (Reviewer, Tester, Security, Docs, Refactor) and is fully CRUD-able in-app: Enter launches the highlighted one, n new, e edit, d delete. Templates live in a hand-editable ~/.config/maestro/quick-agents.toml (seeded on first run).

Broadcast

Press b (OUTSIDE) to fan one prompt out to several sessions at once: a modal lists the running panes (all checked by default — Space toggles), you type a prompt, and Enter sends it to every checked pane. Great for "run the same task across N agents" or kicking off a fleet. Uncheck any pane (e.g. a $SHELL) you don't want.

Skills

Press / (OUTSIDE) to open the skills launcher — a filterable list of the skills in ~/.claude/skills (and a project's .claude/skills). Pick one and maestro types /name into the focused pane and steps you inside, exactly as if you'd typed it in Claude. (Typing /name yourself while INSIDE still works too.)

Maestro also watches each pane's output for Claude's skill markers and shows the active skill as a ⚡<skill> badge on the pane's border (best-effort — it keys off Claude's output text).

Status board

Maestro shows, at a glance, which sessions need you. Each pane gets a best-effort status inferred from output timing:

• ▶ working — producing output right now
• ⏳ waiting — alive but quiet → needs you (a question, an approval, or just done with its turn); the pane border glows amber
• ○ done — exited cleanly · ✗ failed — exited non-zero

There's a dedicated sessions panel on the left listing every pane with its status, your terminal's own title bar summarises it (e.g. maestro ▶2 ⏳1 ○1), and each pane border reflects it too. (Heuristic: maestro can't tell "waiting for approval" from "waiting for your next message" — both show as ⏳ waiting.) The focused pane stands out with a colored border (green while you're INSIDE it) and full-brightness text, while non-focused panes are dimmed. The sessions panel is on by default (toggle with Ctrl+B); a second agents panel with the same rows is off by default (toggle with Ctrl+A); the timeline event log is off by default (toggle with Ctrl+T).

Theme

Maestro defaults to the ansi-dark theme, which draws with your terminal's own 16-colour palette — so it adapts to whatever colour scheme your terminal uses. Press Ctrl+P → "Change theme" to pick another (ansi-light for light terminals, or any of Textual's built-ins like gruvbox / dracula). Your choice is remembered in .maestro/state.json.

Note: Ctrl+Shift+S relies on the terminal forwarding shift+ctrl combos; some terminals fold it into Ctrl+S. claude is the default spawn either way.

Ctrl+] is the only key maestro reserves while INSIDE, so apps that use it (e.g. vim's tag-jump) won't see it.

Layouts

• split — vertical stack; auto-promotes to grid once a 4th pane spawns
• grid — auto-shaped tiles (2×2, 2×3, 3×3, then a scrollable 3×N)
• focused — one large pane plus a left strip of status tiles for the rest

When an agent exits cleanly (exit=0) the pane is auto-dismissed — no frozen-screen confusion. Failed exits (non-zero) stay sticky so you can read what went wrong; press Ctrl+W to dismiss those.

(The panes strip only appears in focused layout. A pane's border turns heavy/green while you're INSIDE it.)

Where things live

• maestro/app.py — Textual app, key bindings, focus-toggle, spawn/dismiss/focus
• maestro/panes.py — Pane model + PaneManager state machine (Textual-agnostic)
• maestro/layouts.py — split / grid / focused renderers + the focus tiles strip
• maestro/terminal.py — pyte-backed Emulator, TerminalView, query responder, key encoder
• maestro/agent.py — PTY-backed subprocess wrapper (ptyprocess); raw bytes + resize
• maestro/events.py — append-only JSONL event log (.maestro/session.jsonl)

.maestro/state.json persists your layout + timeline-visibility choices across restarts. Agent sessions themselves are not resumed.
