OB1 Install & Authentication

Install

curl -fsSL https://dashboard.openblocklabs.com/install | bash

Installs to ~/.ob1/bin/ob1, symlinks to ~/.local/bin/ob1.

Verify: ob1 --version

Authentication

OB1 uses device code flow. Run ob1 and it will display:

To sign in: https://auth.openblocklabs.com/device
Enter code: XXXX-XXXX

Headless/server workflow:

  1. Start ob1 with PTY: the auth URL and code appear in terminal
  2. Send the code to user (via chat) — they open the URL in their browser
  3. User signs in and approves
  4. OB1 shows "Authentication Successful!" and asks to confirm organization
  5. Press Enter to confirm — auth token saved to ~/.ob1/

Important: Each ob1 process generates a unique code. If the process dies, a new code is needed. Keep the process alive until user confirms.

After first auth, all subsequent runs skip login.

Post-Install

  • Default model: Claude Opus 4.6
  • Default mode: Safe YOLO
  • Config: ~/.ob1/settings.json
  • Non-interactive: ob1 -p "task" -y -o text
