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 5.1 | $0.00084 | $0.00884 |
| Opus 5 | $0.00042 | $0.00442 |
| Sonnet 5 | $0.00017 | $0.00177 |
| Haiku 4.5 | $0.00008 | $0.00088 |
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.
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
Control tmux sessions programmatically. Send keys, capture output, run interactive processes.
Cross-platform:
- Linux/macOS: Uses native
tmux - Windows: Uses
psmux(native Windows tmux, 95%+ syntax compatible)
Use tmux when:
- SSH to remote servers (persistent sessions)
- Interactive TTY needed (REPLs, shells, prompts)
- Running multiple processes in parallel
- Orchestrating coding agents
Don't use tmux for:
- Simple background tasks → use
bg runinstead - One-shot commands → run directly
Helper: tmx
Primary: Python CLI tool (tmx) — installable via agent-sommelier-cli.
Fallback: Shell scripts at skills/tmux/scripts/tmx.sh (bash) and tmx.ps1 (PowerShell).
Commands
| Command | Description |
|---|---|
tmx install |
Ensure tmux/psmux is available (auto-install on Windows) |
tmx create <name> [cmd] |
Create session, optionally run init cmd |
tmx rm <name> |
Kill session |
tmx sk <name> "<cmd>" |
Send keys (fire and forget) |
tmx r <name> |
Read output (full scrollback) |
tmx run <name> "<cmd>" [--timeout N] |
Send + wait N seconds + read output |
tmx list [--json] |
List all sessions (rich table or JSON) |
tmx manager |
Interactive session picker |
Quick Start
tmx install
tmx create mysession
tmx run mysession "ls -la"
tmx r mysession
tmx rm mysession
tmx install
tmx create mysession
tmx run mysession "Get-ChildItem"
Pattern 1: SSH Sessions (Most Common)
# Create SSH session
tmx create server "ssh [email protected]"
tmx run server "hostname" --timeout 3
tmx sk server "mypassword"
tmx run server "tail -100 nginx/access.log" --timeout 5
tmx r server
Pattern 2: Background Process Monitoring
tmx create api "cd /app && python api.py"
tmx r api | grep -q "Listening" && echo "API is up"
tmx create db "docker run --name postgres postgres"
tmx list
Pattern 3: Interactive REPL
tmx create python "python3 -q"
tmx run python "import sys; print(sys.version)"
tmx run python "2 + 2" --timeout 3
What ships with it
1 file 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 lirrensi/agent-sommelier (5 stars, last pushed 7d ago), licensed MIT. It adds 84 tokens to every session and 884 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
