tmux

tmux is a skill for Claude Code, Codex from yangkun19921001/PP-Claw. It costs 22 tokens per session (1,279 once invoked), scanned A, a copy of tmux, MIT.

A tool for controlling tmux, a terminal program that keeps command-line sessions running and lets you view them later. It sends keystrokes to interactive command-line programs and reads their screen output.

In plain words
What is it for?
Running and checking interactive command-line tools, Python shells, and other programs that need a terminal session.
Why use it?
It lets an agent operate programs that require a live terminal, even when the work continues in the background or needs monitoring.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tmux scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (find-sessions.sh, scripts/find-sessions.sh, scripts/wait-for-text.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

tmux Skill

Use tmux only when you need an interactive TTY. Prefer exec background mode for long-running, non-interactive tasks.

Quickstart (isolated socket, exec tool)

SOCKET_DIR="${PP_CLAW_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/pp-claw-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/pp-claw.sock"
SESSION=pp-claw-python

tmux -S "$SOCKET" new -d -s "$SESSION" -n shell
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- 'PYTHON_BASIC_REPL=1 python3 -q' Enter
tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200

After starting a session, always print monitor commands:

To monitor:
  tmux -S "$SOCKET" attach -t "$SESSION"
  tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200

Socket convention

  • Use PP_CLAW_TMUX_SOCKET_DIR environment variable.
  • Default socket path: "$PP_CLAW_TMUX_SOCKET_DIR/pp-claw.sock".

Targeting panes and naming

  • Target format: session:window.pane (defaults to :0.0).
  • Keep names short; avoid spaces.
  • Inspect: tmux -S "$SOCKET" list-sessions, tmux -S "$SOCKET" list-panes -a.

Finding sessions

  • List sessions on your socket: {baseDir}/scripts/find-sessions.sh -S "$SOCKET".
  • Scan all sockets: {baseDir}/scripts/find-sessions.sh --all (uses PP_CLAW_TMUX_SOCKET_DIR).

Sending input safely

  • Prefer literal sends: tmux -S "$SOCKET" send-keys -t target -l -- "$cmd".
  • Control keys: tmux -S "$SOCKET" send-keys -t target C-c.

Watching output

  • Capture recent history: tmux -S "$SOCKET" capture-pane -p -J -t target -S -200.
  • Wait for prompts: {baseDir}/scripts/wait-for-text.sh -t session:0.0 -p 'pattern'.
  • Attaching is OK; detach with Ctrl+b d.

Spawning processes

  • For python REPLs, set PYTHON_BASIC_REPL=1 (non-basic REPL breaks send-keys flows).

Windows / WSL

  • tmux is supported on macOS/Linux. On Windows, use WSL and install tmux inside WSL.
  • This skill is gated to darwin/linux and requires tmux on PATH.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
