OpenAgent is a self-hostable personal AI assistant that combines language models, document-based retrieval, and autonomous agent loops. It lets people connect model providers and their own knowledge bases, then have agents browse the web, run code, use computers, and call MCP-compatible tools.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00022 | $0.00729 |
| Opus 5.5 | $0.00009 | $0.00292 |
| Sonnet 5.5 | $0.00004 | $0.00146 |
| Haiku 4.5 | $0.00002 | $0.00073 |
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
tmux Session Control
Control tmux sessions by sending keystrokes and reading output. Essential for managing long-running terminal sessions.
When to Use
✅ USE this skill when:
- Monitoring sessions in tmux
- Sending input to interactive terminal applications
- Scraping output from long-running processes in tmux
- Navigating tmux panes/windows programmatically
- Checking on background work in existing sessions
When NOT to Use
❌ DON'T use this skill when:
- Running one-off shell commands → run them directly
- Starting new background processes → use shell backgrounding
- Non-interactive scripts → run them directly
- The process isn't in tmux
- You need to create a new tmux session → use
tmux new-session
Common Commands
List Sessions
tmux list-sessions
tmux ls
Capture Output
# Last 20 lines of pane
tmux capture-pane -t shared -p | tail -20
# Entire scrollback
tmux capture-pane -t shared -p -S -
# Specific pane in window
tmux capture-pane -t shared:0.0 -p
Send Keys
# Send text (doesn't press Enter)
tmux send-keys -t shared "hello"
# Send text + Enter
tmux send-keys -t shared "y" Enter
# Send special keys
tmux send-keys -t shared Enter
tmux send-keys -t shared Escape
tmux send-keys -t shared C-c # Ctrl+C
tmux send-keys -t shared C-d # Ctrl+D (EOF)
tmux send-keys -t shared C-z # Ctrl+Z (suspend)
Window/Pane Navigation
# Select window
tmux select-window -t shared:0
# Select pane
tmux select-pane -t shared:0.1
# List windows
tmux list-windows -t shared
Session Management
# Create new session
tmux new-session -d -s newsession
# Kill session
tmux kill-session -t sessionname
# Rename session
tmux rename-session -t old new
Sending Input Safely
For interactive TUIs, split text and Enter into separate sends to avoid paste/multiline edge cases:
tmux send-keys -t shared -l -- "Please apply the patch in src/foo.ts"
sleep 0.1
tmux send-keys -t shared Enter
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.
- 1mo ago First seen · 125 lines · 22 tokens per session scan A a3463c9d4c07
tmux is a skill published in the GitHub repository the-open-agent/openagent (5,698 stars, last pushed yesterday), licensed Apache-2.0. It adds 22 tokens to every session and 729 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
