The Three Agents
You have three powerful coding agents installed, each from a different AI company:
claudecccodexcodgeminigmiWhat The Aliases Do
The aliases are configured for maximum power (vibe mode):
cc(Claude Code)NODE_OPTIONS="--max-old-space-size=32768" \ claude --dangerously-skip-permissions
- Extra memory for large projects
- Background tasks enabled by default
- No permission prompts
cod(Codex CLI)codex --dangerously-bypass-approvals-and-sandbox
- Bypass safety prompts
- No approval/sandbox checks
gmi(Gemini CLI)gemini --yolo
- YOLO mode (no confirmations)
First Login
Each agent needs to be authenticated once:
Claude Code
$ claude auth loginFollow the browser link to authenticate with your Anthropic account.
Codex CLI
On a headless VPS, Codex requires special handling because its OAuth callback expects localhost:1455.
Option 1: Device Auth (Recommended)
- Enable "Device code login" in ChatGPT Settings → Security
- Then run the command below
$ codex login --device-authOption 2: SSH Tunnel
- On your laptop, create a tunnel
- Then run
codex loginon VPS
# On laptop: $ ssh -L 1455:localhost:1455 ubuntu@YOUR_VPS_IP # Then on VPS: $ codex login
Option 3: Standard (if you have a browser)
$ codex loginChatGPT (Pro/Plus/Team)
- • For Codex CLI, ChatGPT web
- • Auth via OAuth (`codex login`)
- • Get at chat.openai.com
API (pay-as-you-go)
- • For OpenAI API, libraries
- • Uses OPENAI_API_KEY env var
- • Get at platform.openai.com
Codex CLI uses ChatGPT OAuth, not API keys. If you have an OPENAI_API_KEY, that's for the API—different system!
If login fails: Check ChatGPT Settings → Security → "API/Device access"
Gemini CLI
$ geminiFollow the prompts to authenticate with your Google account.
Backup Your Credentials!
After logging in, immediately back up your credentials:
caam backup claude my-main-accountcaam backup codex my-main-accountcaam backup gemini my-main-account
Now you can switch accounts later with:
caam activate claude my-other-account
Test Your Agents
Try each one to verify they're working:
cc "Hello! Please confirm you're working."
cod "Hello! Please confirm you're working."
gmi "Hello! Please confirm you're working."
Quick Tips
- Start simple - Let agents do small tasks first
- Be specific - Clear instructions get better results
- Check the output - Agents can make mistakes
- Use multiple agents - Different agents have different strengths
