Context Window

Your AI has a context window — the amount of conversation it can hold in active memory at once. Think of it like a whiteboard: the more you write, the less room remains.

0-60% Green
60-85% Caution
85%+

Green zone — Plenty of room. Your AI remembers everything in this conversation with full clarity.

Yellow zone — Getting full. Your AI may start compressing older parts of the conversation. Consider wrapping up complex topics.

Red zone — Near capacity. Your AI will need to restart soon to continue working effectively. Don't worry — your chat history is saved.

⌘ Server Commands
🏥Health Check
Verify Meridian is alive and the session is active.
Connect & Check
ssh aiciv@37.27.237.109
tmux list-sessions
systemctl status meridian-session.service --no-pager
systemctl status meridian-telegram.service --no-pager
exit
Healthy: You should see an active tmux session like "meridian: 1 windows (created ...)"
Unhealthy: "no server running on /tmp/tmux-1000/default" means Meridian needs a restart.
📺Live Monitoring
Watch exactly what Meridian is doing in real time.
Connect & Attach
ssh aiciv@37.27.237.109
tmux list-sessions
tmux attach -t meridian
IMPORTANT: Always detach with Ctrl+B then D. Never close terminal while attached.
Quick Peek (without attaching)
tmux capture-pane -t meridian -p | tail -30

🔑Mac SSH Key Setup
One-time setup to enable password-less SSH from your Mac.
Step 1: Check for Existing Keys
ls ~/.ssh/id_ed25519.pub ~/.ssh/id_rsa.pub 2>/dev/null
If a key file is listed, skip to Step 3. If nothing shows, create one in Step 2.
Step 2: Generate New Key
ssh-keygen -t ed25519 -C "meridian-access"
Step 3: Copy Key to Server
ssh-copy-id aiciv@37.27.237.109
Step 4: Create Quick Alias
echo "alias meridian='ssh -t aiciv@37.27.237.109 bash /home/aiciv/civ/tools/connect-meridian.sh'" >> ~/.zshrc && source ~/.zshrc
After setup, just type meridian in any terminal to connect.
One-Word Terminal Setup
After SSH key setup, create a magic word that instantly connects you to Meridian's live session.
Server-side: Create connect-meridian.sh
#!/bin/bash # connect-meridian.sh — placed on the server at /home/aiciv/civ/tools/ SESSION=$(tmux list-sessions -F '#{session_name}' 2>/dev/null | head -1) if [ -z "$SESSION" ]; then echo "No active Meridian session found." exit 1 fi echo "Attaching to Meridian session: $SESSION" tmux attach -t "$SESSION"
Mac-side: Add Alias
echo "alias meridian='ssh -t aiciv@37.27.237.109 bash /home/aiciv/civ/tools/connect-meridian.sh'" >> ~/.zshrc && source ~/.zshrc
The -t flag is critical. The alias MUST include -t in the SSH command for tmux to work properly.
Usage
meridian
Type meridian in any terminal → instantly see what Meridian is doing. Disconnect safely with Ctrl+B then D.
