Da Vinci Console

A focused tmux session picker built with fzf — plus a herdr-style agent dashboard that shows which coding agents are running and where, all inside tmux.

It only cares about tmux: sessions, windows, panes, agents, and a good-looking live preview.

Features

• Tmux sessions with nested windows
• Agent-aware: each coding agent is nested directly under its own window with a status light (◐ focused / ● working / ○ idle). No separate agents panel — they live with their window and are clickable to jump to it
• Live preview of the selected session or window
• Pane drill-down when a window has multiple panes
• Create, rename, and kill directly from the picker
• Broadcast: select multiple panes and send one command to all of them (great for parallel tool runs across an engagement)
• A shareable extras/tmux.conf that puts the same agent status lights in your tmux status-line window pills — so agents are visible everywhere, not just in the picker

How it works

Agents are detected by walking each window pane's process tree for known agent command names (pi claude codex opencode gemini aider cursor-agent grok continue qwen-code — override with TMUX_AGENTS). "Working" is approximated by CPU-time growth between refreshes.

The detection logic lives in agents/, shared by both the picker and the tmux status line:

agents/
├── lib.sh            # shared watch-list + detection
├── agents_state.sh   # all agents + status lights (feeds the picker)
├── window_agent.sh   # " | pi ●" for one window (feeds the status line)
└── jump.sh           # <prefix>+a fzf picker across all agents

Broadcast

<prefix>+B opens a floating picker of every pane across all sessions. Use Tab to toggle selection (or Ctrl-A to select all), then Enter to pick a command (with recent-command history). It's sent + Enter to each selected pane — e.g. kick off the same nmap/netexec/update against several panes at once.

Requirements

Tool	Notes
tmux	Required
fzf	Required
Nerd Font (e.g. JetBrainsMono Nerd Font)	Recommended — for the icons

Install

git clone https://github.com/purehate/Da_Vinci_Console
cd Da_Vinci_Console
./install.sh

The installer copies the picker to ~/.config/tmux/sesh_picker.sh, the dynamic-size popup wrapper to ~/.config/tmux/picker_popup.sh, and the agent module to ~/.config/tmux/agents/.

Tmux status line (agents in the window pills)

The repo ships a complete shareable config in extras/tmux.conf that turns your status line into an agent dashboard:

1:acme | pi ◐   2:api | claude ○   3:workers   4:docs | codex ●

Each window pill shows | agent ⦁; click a pill to jump to that window. No agent → the pill looks normal.

The same extras/tmux.conf also draws a live pane border with the current path, the running agent's light, and the git branch — so the agent follows you around the window, not just in the status line or picker.

Its status-right is a compact powerline block: git branch, pane count, and the date/time. The status-left shows just the session name. Window pills sit left-justified. The status-interval of 2s lets the "working" light spin while an agent is burning CPU.

cp extras/tmux.conf ~/.config/tmux/tmux.conf   # back up yours first!
tmux source-file ~/.config/tmux/tmux.conf       # or <prefix>+r

Or just add the picker binding to your existing config:

bind-key s run-shell "~/.config/tmux/picker_popup.sh"
bind-key B run-shell "~/.config/tmux/broadcast_popup.sh"

The picker_popup.sh wrapper sizes the popup to fit the list (dynamic height

• width) with an opaque background, so it hugs the content and reads cleanly regardless of terminal transparency.

Keybindings

Key	Action
Enter	Switch to selected session/window
Ctrl-N	Create a new session
Ctrl-R	Rename selected session/window
Ctrl-D	Kill selected session/window
Ctrl-G	Filter to agent windows only
Ctrl-T	Show all sessions/windows
Ctrl-/	Toggle preview
Alt-Up / Alt-Down	Scroll preview
Esc / Ctrl-C	Exit

Outside the picker (<prefix>+B): broadcast a command to multiple panes.

Agent status lights

• ◐ — focused (the window/pane you're viewing)
• ◓ ◑ ◒ ◔ — working (CPU time grew since last refresh; the light spins)
• ○ — idle

Each agent also gets its own brand colour (pi=green, claude=orange, codex=red, gemini=blue, aider=pink, opencode=teal, …) so you can scan who's running where at a glance — in the picker, the preview, and the session summaries. (Colours show in the picker; the status-line pills inherit the pill's own colour.)

Icons

Icons are Nerd Font glyphs, shared by the picker rows and the tmux status-line window pills via app_icon() in agents/lib.sh / icon_for() in da-vinci-console.sh. A Nerd Font is required in your terminal to see them (e.g. brew install --cask font-jetbrains-mono-nerd-font) — without one the icon space collapses to blank. Edit those functions to customise.
