CRITICAL: Never use Read, Edit, or Write tools on ~/.cyrus/.env or any file inside ~/.cyrus/. Use only Bash commands (grep, printf >>, etc.) to interact with env files — secrets must never be read into the conversation context.

Setup Launch

Prints a summary of the completed setup and offers to start Cyrus.

Step 1: Gather Configuration

Read current state:

# Base URL
grep '^CYRUS_BASE_URL=' ~/.cyrus/.env 2>/dev/null | cut -d= -f2-

# Linear
grep -c '^LINEAR_CLIENT_ID=' ~/.cyrus/.env 2>/dev/null

# GitHub
gh auth status 2>&1 | head -1

# Slack
grep -c '^SLACK_BOT_TOKEN=' ~/.cyrus/.env 2>/dev/null

# Repositories
cat ~/.cyrus/config.json 2>/dev/null

# Claude auth
grep -c -E '^(ANTHROPIC_API_KEY|CLAUDE_CODE_OAUTH_TOKEN)=' ~/.cyrus/.env 2>/dev/null

Step 2: Print Summary

Print a formatted summary:

┌─────────────────────────────────────┐
│         Cyrus Setup Complete        │
├─────────────────────────────────────┤
│                                     │
│  Endpoint: https://your-url.com     │
│  Claude:   ✓ API key configured     │
│                                     │
│  Surfaces:                          │
│    Linear:  ✓ Workspace connected   │

│    Slack:   ✓ Bot configured        │
│                                     │
│  Repositories:                      │
│    • yourorg/yourrepo               │
│    • yourorg/another-repo           │
│                                     │
└─────────────────────────────────────┘

Use ✓ for configured items and ✗ for skipped/unconfigured items.

Step 3: Make Cyrus Persistent

Cyrus needs to run as a background process so it stays alive and restarts after reboots. Use the AskUserQuestion tool if available to ask:

How would you like to keep Cyrus running in the background?

1. pm2 (recommended) — Node.js process manager. Simple to set up, auto-restarts on crash, log management built in. Best for most users.
2. systemd (Linux only) — OS-level service manager. Starts on boot automatically, managed with systemctl. Best for dedicated Linux servers.
3. Neither — just run cyrus in the foreground for now (you can set up persistence later).

Option 1: pm2

The agent should run all of these commands directly:

1. Check if pm2 is installed (which pm2). If not, install it (npm install -g pm2).
2. Start Cyrus: pm2 start cyrus --name cyrus
3. Save the process list: pm2 save
4. Run pm2 startup — this prints a system-specific command. The agent should run that output command too (it typically requires sudo).

After setup, inform the user of useful commands:

• pm2 logs cyrus — view logs
• pm2 restart cyrus — restart
• pm2 stop cyrus — stop

Option 2: systemd (Linux only)

The agent should run all of these commands directly:

1. Resolve the actual values for the service file:

``bash CYRUSBIN=$(which cyrus) CYRUSUSER=$(whoami) ``

1. Write the service file:

```bash sudo tee /etc/systemd/system/cyrus.service > /dev/null << EOF [Unit] Description=Cyrus AI Agent After=network.target

[Service] Type=simple User=$CYRUSUSER EnvironmentFile=/home/$CYRUSUSER/.cyrus/.env ExecStart=$CYRUS_BIN Restart=always RestartSec=10

[Install] WantedBy=multi-user.target EOF ```

1. Enable and start:

``bash sudo systemctl daemon-reload sudo systemctl enable cyrus sudo systemctl start cyrus ``

After setup, inform the user of useful commands:

• sudo systemctl status cyrus — check status
• sudo journalctl -u cyrus -f — view logs
• sudo systemctl restart cyrus — restart

Option 3: Foreground

Run directly:

cyrus

Step 4: Start ngrok (if applicable)

If the user configured ngrok in the endpoint step, the agent should start it:

ngrok start cyrus

If using pm2, also make ngrok persistent:

pm2 start "ngrok start cyrus" --name ngrok
pm2 save

Step 5: Sandbox CA Certificate Trust (if sandbox enabled)

If the user's ~/.cyrus/config.json has sandbox.enabled: true, check whether the egress proxy CA certificate is trusted in the system keychain.

Check if sandbox is enabled:

grep -o '"enabled":\s*true' ~/.cyrus/config.json 2>/dev/null | head -1

If sandbox is enabled, check trust status:

# macOS — check System keychain for the Cyrus CA
security find-certificate -c "Cyrus Egress Proxy CA" /Library/Keychains/System.keychain 2>&1

• If the cert is found (exit code 0): report ✓ trusted. Offer to set sandbox.systemWideCert: true in config.json to skip per-session cert env vars.
• If not found (exit code 44): inform the user and offer to run the trust command:

sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~/.cyrus/certs/cyrus-egress-ca.pem

On Linux, check with test -f /usr/local/share/ca-certificates/cyrus-egress-ca.crt. If not present:

sudo cp ~/.cyrus/certs/cyrus-egress-ca.pem /usr/local/share/ca-certificates/cyrus-egress-ca.crt
sudo update-ca-certificates

After trusting system-wide, offer to set sandbox.systemWideCert: true in config.json. This skips per-session cert env vars (NODEEXTRACACERTS, GITSSL_CAINFO, etc.) since the OS cert store handles trust for all tools.

If the user declines system-wide trust, Cyrus still works — it sets cert env vars per-session. But some tools (Bun, .NET, curl on macOS with SecureTransport) will only work with system-wide trust.

Step 6: Verify Running

Once Cyrus starts, verify it's listening:

curl -s http://localhost:3456/status

Should return {"status":"idle"} or similar.

Then try assigning a Linear issue to Cyrus, or @mentioning it in Slack, to verify the full pipeline works!

Completion

✓ Cyrus is running and ready. Assign a Linear issue or @mention in Slack to test it out!
