What problem does it solve? Managing credentials and secrets across projects often leads to insecure practices like hardcoding passwords or pasting them into chat. This Skill guides the setup and use of the 1Password CLI so secrets are read, injected, or passed to commands without ever being written to disk or logs. ## Core Features & Use Cases - CLI Setup and Sign-In: Walks through installing the 1Password CLI, enabling desktop app integration, and authenticating via op signin. - Secret Reading and Injection: Reads secrets with op read, injects them into config templates with op inject, and runs commands with secrets via op run. - Safe Session Handling: Runs all op commands inside a dedicated tmux session to avoid repeated authentication prompts and TTY failures. - Use Case: You need a database password for a deployment script. Instead of copying it into a file, use op run --env-file to inject the secret at runtime directly from your 1Password vault. ## Quick Start Set up the 1Password CLI on this machine, sign me in, and read the database password from my app-prod vault without printing it to the chat.
