# Install minimal system dependencies
# Install minimal system dependencies + the agent-CLI / TUI-debug toolkit.
# Bundle includes: tmux for script-driven multiplexing (claude can `new-session
# -d`, `send-keys`, `capture-pane -p`); expect for driving interactive prompts;
# neovim for in-container quick edits; ripgrep/fd-find/bat for fast search +
# pretty file inspection (claude reaches for these constantly); fzf for
# fuzzy completion in interactive shells.
# Note: on Debian, fd-find ships as `fdfind` and bat as `batcat` — we add
# convenience symlinks below so claude can call `fd` and `bat` directly.
