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 on macOS, Linux, or Windows and authenticate via desktop app integration, service account token, or 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 Agent Sessions: Use a dedicated tmux session pattern so desktop-app sign-in persists across non-interactive terminal calls. - Use Case: A developer needs a database password for a deployment script without storing it in a file. The Skill authenticates op with a service account token and runs the script with op run so the secret is injected only at runtime. ## Quick Start Set up the 1Password CLI with a service account token and read the database password from my app-prod vault.
