Had a broken frontmatter (missing opening `---` delimiter) and decided
not to keep it — prefer to handle interactive CLIs differently.

-# tmux Skill
-
-Use tmux as a programmable terminal multiplexer for interactive work. Works on Linux and macOS with stock tmux; avoid custom config by using a private socket.
-
-## Quickstart (isolated socket)
-
-```bash
-SOCKET_DIR=${TMPDIR:-/tmp}/claude-tmux-sockets  # well-known dir for all agent sockets
-mkdir -p "$SOCKET_DIR"
-SOCKET="$SOCKET_DIR/claude.sock"                # keep agent sessions separate from your personal tmux
-SESSION=claude-python                           # slug-like names; avoid spaces
-tmux -S "$SOCKET" new -d -s "$SESSION" -n shell
-tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- 'python3 -q' Enter
-tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200  # watch output
-tmux -S "$SOCKET" kill-session -t "$SESSION"                   # clean up
-```
-
-After starting a session ALWAYS tell the user how to monitor the session by giving them a command to copy paste:
-
-```
-To monitor this session yourself:
-  tmux -S "$SOCKET" attach -t claude-lldb
-
-Or to capture the output once:
-  tmux -S "$SOCKET" capture-pane -p -J -t claude-lldb:0.0 -S -200
-```
-
-This must ALWAYS be printed right after a session was started and once again at the end of the tool loop.  But the earlier you send it, the happier the user will be.

-## Socket convention
-
-- Agents MUST place tmux sockets under `CLAUDE_TMUX_SOCKET_DIR` (defaults to `${TMPDIR:-/tmp}/claude-tmux-sockets`) and use `tmux -S "$SOCKET"` so we can enumerate/clean them. Create the dir first: `mkdir -p "$CLAUDE_TMUX_SOCKET_DIR"`.
-- Default socket path to use unless you must isolate further: `SOCKET="$CLAUDE_TMUX_SOCKET_DIR/claude.sock"`.
-
-## Targeting panes and naming
-
-- Target format: `{session}:{window}.{pane}`, defaults to `:0.0` if omitted. Keep names short (e.g., `claude-py`, `claude-gdb`).
-- Use `-S "$SOCKET"` consistently to stay on the private socket path. If you need user config, drop `-f /dev/null`; otherwise `-f /dev/null` gives a clean config.
-- Inspect: `tmux -S "$SOCKET" list-sessions`, `tmux -S "$SOCKET" list-panes -a`.
-
-## Finding sessions
-
-- List sessions on your active socket with metadata: `./tools/find-sessions.sh -S "$SOCKET"`; add `-q partial-name` to filter.
-- Scan all sockets under the shared directory: `./tools/find-sessions.sh --all` (uses `CLAUDE_TMUX_SOCKET_DIR` or `${TMPDIR:-/tmp}/claude-tmux-sockets`).
-
-## Sending input safely
-
-- Prefer literal sends to avoid shell splitting: `tmux -L "$SOCKET" send-keys -t target -l -- "$cmd"`
-- When composing inline commands, use single quotes or ANSI C quoting to avoid expansion: `tmux ... send-keys -t target -- $'python3 -m http.server 8000'`.
-- To send control keys: `tmux ... send-keys -t target C-c`, `C-d`, `C-z`, `Escape`, etc.
-
-## Watching output
-
-- Capture recent history (joined lines to avoid wrapping artifacts): `tmux -L "$SOCKET" capture-pane -p -J -t target -S -200`.
-- For continuous monitoring, poll with the helper script (below) instead of `tmux wait-for` (which does not watch pane output).
-- You can also temporarily attach to observe: `tmux -L "$SOCKET" attach -t "$SESSION"`; detach with `Ctrl+b d`.
-- When giving instructions to a user, **explicitly print a copy/paste monitor command** alongside the action don't assume they remembered the command.
-
-## Spawning Processes
-
-Some special rules for processes:
-
-- when asked to debug, use lldb by default
-- when starting a python interactive shell, always set the `PYTHON_BASIC_REPL=1` environment variable. This is very important as the non-basic console interferes with your send-keys.
-
-## Synchronizing / waiting for prompts
-
-- Use timed polling to avoid races with interactive tools. Example: wait for a Python prompt before sending code:
-  ```bash
-  ./tools/wait-for-text.sh -t "$SESSION":0.0 -p '^>>>' -T 15 -l 4000
-  ```
-- For long-running commands, poll for completion text (`"Type quit to exit"`, `"Program exited"`, etc.) before proceeding.
-
-## Interactive tool recipes
-
-- **Python REPL**: `tmux ... send-keys -- 'python3 -q' Enter`; wait for `^>>>`; send code with `-l`; interrupt with `C-c`. Always with `PYTHON_BASIC_REPL`.
-- **gdb**: `tmux ... send-keys -- 'gdb --quiet ./a.out' Enter`; disable paging `tmux ... send-keys -- 'set pagination off' Enter`; break with `C-c`; issue `bt`, `info locals`, etc.; exit via `quit` then confirm `y`.
-- **Other TTY apps** (ipdb, psql, mysql, node, bash): same pattern—start the program, poll for its prompt, then send literal text and Enter.
-
-## Cleanup
-
-- Kill a session when done: `tmux -S "$SOCKET" kill-session -t "$SESSION"`.
-- Kill all sessions on a socket: `tmux -S "$SOCKET" list-sessions -F '#{session_name}' | xargs -r -n1 tmux -S "$SOCKET" kill-session -t`.
-- Remove everything on the private socket: `tmux -S "$SOCKET" kill-server`.
-
-## Helper: wait-for-text.sh
-
-`./tools/wait-for-text.sh` polls a pane for a regex (or fixed string) with a timeout. Works on Linux/macOS with bash + tmux + grep.
-
-```bash
-./tools/wait-for-text.sh -t session:0.0 -p 'pattern' [-F] [-T 20] [-i 0.5] [-l 2000]
-```
-
-- `-t`/`--target` pane target (required)
-- `-p`/`--pattern` regex to match (required); add `-F` for fixed string
-- `-T` timeout seconds (integer, default 15)
-- `-i` poll interval seconds (default 0.5)
-- `-l` history lines to search from the pane (integer, default 1000)
-- Exits 0 on first match, 1 on timeout. On failure prints the last captured text to stderr to aid debugging.
