What problem does it solve? Setting up the 1Password CLI (op) and authenticating it correctly involves OS-specific install steps, desktop app integration, and session handling that often fails when commands run in fresh shells. This Skill guides the full setup and sign-in flow so secret reads, injections, and runs work reliably. ## Core Features & Use Cases - CLI Setup & App Integration: Walks through installing the 1Password CLI and enabling desktop app integration on macOS, Windows, and Linux. - Authenticated Secret Access: Handles single and multi-account sign-in, then reads, injects, or runs commands with secrets via op read, op inject, and op run. - tmux Session Management: Runs all op commands inside a dedicated tmux session to avoid repeated authorization prompts caused by fresh TTYs. - Use Case: A developer needs a database password from a shared vault in a CI-like shell. The Skill verifies op is installed, signs in through the desktop app inside tmux, and runs op run --env-file to inject the secret without writing it to disk. ## Quick Start Use the 1password skill to sign in to my 1Password account and read the database password from my app-prod vault.
