Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00022 | $0.01307 |
| Opus 5 | $0.00011 | $0.00654 |
| Sonnet 5 | $0.00004 | $0.00261 |
| Haiku 4.5 | $0.00002 | $0.00131 |
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 2d ago.
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.
This is a copy
80% identical to tmux — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

tmux Skill (Clawdbot)
Use tmux only when you need an interactive TTY. Prefer bash background mode for long-running, non-interactive tasks.
Quickstart (isolated socket, bash tool)
SOCKET_DIR="${CLAWDBOT_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/clawdbot-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/clawdbot.sock"
SESSION=clawdbot-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
CLAWDBOT_TMUX_SOCKET_DIR(default${TMPDIR:-/tmp}/clawdbot-tmux-sockets). - Default socket path:
"$CLAWDBOT_TMUX_SOCKET_DIR/clawdbot.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 "$SOCKET". - Scan all sockets:
{baseDir}/scripts/find-sessions.sh --all(usesCLAWDBOT_TMUX_SOCKET_DIR).
Sending input safely
- Prefer literal sends:
tmux -S "$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/linuxand requirestmuxon 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.
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.

tmux is a skill published in the GitHub repository zai-org/Synapse (438 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 22 tokens to every session and 1,307 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 80% identical to tmux, differing in 20 lines, and is treated as a copy.
