What problem does it solve? Managing secrets through plaintext environment variables or config files exposes credentials and complicates rotation. This Skill sets up the 1Password CLI (op) so secrets are read, injected, or passed to commands directly from a 1Password vault. ## Core Features & Use Cases - CLI Setup and Authentication: Install op and authenticate via service account token, desktop app integration, or a self-hosted Connect server. - Secret Operations: Read secrets with op:// references, fetch one-time passwords, inject secrets into templates with op inject, and run commands with secret env vars via op run. - Stable Terminal Sessions: Use a dedicated tmux session for desktop app sign-in flows so authentication persists across non-interactive terminal calls. - Use Case: A developer needs a database password for a deployment script. Instead of pasting it into a .env file, they run the command with op run so the secret is resolved at runtime from the vault. ## Quick Start Set up the 1Password CLI with a service account token and read the database password from my app-prod vault.
