sx

A small TUI for tmux sessions + git-worktree agent workflows. Each task gets its own git worktree (isolation) running in its own tmux session.

Install

go install github.com/m7medVision/sx@latest

Bound in ~/.tmux.conf:

bind-key s run-shell '$HOME/go/bin/sx'

Press prefix s to open it.

Keys

Key	Action
enter	switch to the selected session
ctrl-n	new plain session (prompts for a name)
ctrl-w	new git-worktree session (pick or type a branch)
ctrl-x	kill the selected session (asks before removing a worktree)
esc/q	cancel
?	show help
c	edit config (global + per-project)

ctrl-w only appears inside a git repo. New worktrees go to <repo>/.worktrees/<branch> and .worktrees/ is auto-added to .gitignore.

Config

Worktrees are clean checkouts with no gitignored files. Tell sx what to bring in via ~/.config/sx/config.yaml and/or per-project .sx.yaml (project wins).

Press c to edit config from inside the TUI. The config view has two scopes, toggled with tab (only when you're inside a git repo):

• global — ~/.config/sx/config.yaml
• project — .sx.yaml at the repo root

Keys in the config view:

Key	Action
tab	switch scope (global ↔ project)
↑/↓	move between worktree_dir, copy, symlink
a	add a file (mini-fzf picker) or edit (worktree_dir / global scope)
d	delete the highlighted glob
e	edit the highlighted line (dir or globs)
enter	save the active scope to disk
q/esc	close without saving

When you press a on files.copy / files.symlink inside a git repo, a mini-fzf opens: type to fuzzy-filter, tab to multi-select, ↑/↓ or j/k to move, enter to add all marked (or the current line), esc to leave the picker. The footer flashes ✓ added N file(s) for ~2 seconds after each commit.

Edits apply to whichever scope is active; the other scope's file is untouched. Save writes only the configured fields, so agent-detection markers already in the file are preserved.

worktree_dir: .worktrees
files:
  copy:
    - .env
    - .env.*
  symlink:
    - node_modules
