What cyrus-setup-launch does

The skill inspects local configurations in ~/.cyrus/.env and ~/.cyrus/config.json. It formats a summary table showing whether credentials for Linear, GitHub, Slack, and Claude are set up before running the agent.

Cyrus needs to stay online after reboots. The skill asks how to handle persistence, offering pm2, a Linux systemd unit, or running directly in the foreground. If proxy sandboxing is enabled, it also verifies CA certificate trust in the operating system store.

Secrets are guarded by an explicit restriction. The agent is forbidden from loading ~/.cyrus/.env using file read tools, relying on grep instead to protect keys from conversational context. Creating systemd units or installing root certificates requires sudo access.

What it helps with

  • audit Cyrus connection status for Linear, GitHub, and Slack
  • configure background persistence using pm2 or systemd
  • install Cyrus egress proxy CA certificate into the system keychain
  • start and persist ngrok tunnels for external endpoints

Example prompts for the agent

  • Check my Cyrus setup and launch the agent in the background using pm2
  • Review Cyrus configuration and generate a systemd service file
  • Show the Cyrus setup summary and start it in the foreground

Questions about cyrus-setup-launch

How do I install cyrus-setup-launch in Claude Code?

Run npx skills add cyrusagents/cyrus --skill cyrus-setup-launch -a claude-code in your terminal.

What does cyrus-setup-launch do?

It validates your Cyrus setup, displays a summary of connected surfaces, and configures background execution using pm2 or systemd.

Why does the skill avoid reading .env files directly?

The skill instructions explicitly ban file reading tools on environment files. It relies on Bash and grep so API keys stay out of the conversation context.

**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:

```bash
# 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   │
│    GitHub:  ✓ CLI authenticated     │
│    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
   CYRUS_BIN=$(which cyrus)
   CYRUS_USER=$(whoami)
   ```

2. 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=$CYRUS_USER
   EnvironmentFile=/home/$CYRUS_USER/.cyrus/.env
   ExecStart=$CYRUS_BIN
   Restart=always
   RestartSec=10

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

3. 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:

```bash
cyrus
```

## Step 4: Start ngrok (if applicable)

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

```bash
ngrok start cyrus
```

If using pm2, also make ngrok persistent:

```bash
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:**

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

If sandbox is enabled, check trust status:

```bash
# 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:

```bash
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:

```bash
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 (`NODE_EXTRA_CA_CERTS`, `GIT_SSL_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:

```bash
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!
