What problem does it solve? Managing secrets and credentials across development environments often leads to insecure practices like hardcoding passwords or pasting secrets into logs. This Skill guides you through installing, authenticating, and using the 1Password CLI (op) so secrets are read, injected, or run securely without exposing them. ## Core Features & Use Cases - CLI Setup and Sign-In: Walks through installing the op CLI, enabling desktop app integration, and signing in to single or multiple accounts. - Secure Secret Access: Reads secrets via op read, injects them into config files with op inject, or runs commands with secrets via op run without writing them to disk. - tmux Session Management: Runs all op commands inside a dedicated tmux session to avoid repeated authentication prompts and TTY failures. - Use Case: A developer needs a database password for a deployment script. Instead of copying it into a .env file, they use op run --env-file to inject the secret at runtime directly from their 1Password vault. ## Quick Start Ask the assistant to set up the 1Password CLI, sign in to your account, and read a specific secret from a vault using an op:// reference.
