1Password CLI

SkillDev tools

Set up op CLI, sign in, and read or inject secrets.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the 1Password CLI skill

What this skill tells your AI

The instructions your AI receives, as published by h4dex/opc-nexus in vendor/hermes-agent/optional-skills/security/1password/SKILL.md and read by ahel’s review.

Use this skill when the user wants secrets managed through 1Password instead of plaintext env vars or files.

Requirements

  • 1Password account
  • 1Password CLI (op) installed
  • One of: desktop app integration, service account token (OP_SERVICE_ACCOUNT_TOKEN), or Connect server
  • tmux available for stable authenticated sessions during Hermes terminal calls (desktop app flow only)

When to Use

  • Install or configure 1Password CLI
  • Sign in with op signin
  • Read secret references like op://Vault/Item/field
  • Inject secrets into config/templates using op inject
  • Run commands with secret env vars via op run

Authentication Methods

Service Account (recommended for Hermes)

Set OP_SERVICE_ACCOUNT_TOKEN in ${HERMES_HOME:-~/.hermes}/.env (the skill will prompt for this on first load). No desktop app needed. Supports op read, op inject, op run.

export OP_SERVICE_ACCOUNT_TOKEN="your-token-here"
op whoami  # verify — should show Type: SERVICE_ACCOUNT

Desktop App Integration (interactive)

  1. Enable in 1Password desktop app: Settings → Developer → Integrate with 1Password CLI
  2. Ensure app is unlocked
  3. Run op signin and approve the biometric prompt

Connect Server (self-hosted)

export OP_CONNECT_HOST="http://localhost:8080"
export OP_CONNECT_TOKEN="your-connect-token"

Setup

  1. Install CLI:
# macOS
brew install 1password-cli

# Linux (official package/install docs)
# See references/get-started.md for distro-specific links.

# Windows (winget)
winget install AgileBits.1Password.CLI
  1. Verify:
op --version
  1. Choose an auth method above and configure it.

Hermes Execution Pattern (desktop app flow)

Hermes terminal commands are non-interactive by default and can lose auth context between calls. For reliable op use with desktop app integration, run sign-in and secret operations inside a dedicated tmux session.

Note: This is NOT needed when using OP_SERVICE_ACCOUNT_TOKEN — the token persists across terminal calls automatically.

SOCKET_DIR="${TMPDIR:-/tmp}/hermes-tmux-sockets"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/hermes-op.sock"
SESSION="op-auth-$(date +%Y%m%d-%H%M%S)"

tmux -S "$SOCKET" new -d -s "$SESSION" -n shell

# Sign in (approve in desktop app when prompted)
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "eval \"\$(op signin --account my.1password.com)\"" Enter

# Verify auth
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "op whoami" Enter

# Example read
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "op read 'op://Private/Npmjs/one-time password?attribute=otp'" Enter

# Capture output when needed
tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200

# Cleanup
tmux -S "$SOCKET" kill-session -t "$SESSION"

Common Operations

Read a secret

op read "op://app-prod/db/password"

Get OTP

op read "op://app-prod/npm/one-time password?attribute=otp"

Inject into template

echo "db_password: {{ op://app-prod/db/password }}" | op inject

Run a command with secret env var

export DB_PASSWORD="op://app-prod/db/password"
op run -- sh -c '[ -n "$DB_PASSWORD" ] && echo "DB_PASSWORD is set" || echo "DB_PASSWORD missing"'

Guardrails

  • Never print raw secrets back to user unless they explicitly request the value.
  • Prefer op run / op inject instead of writing secrets into files.
  • If command fails with "account is not signed in", run op signin again in the same tmux session.
  • If desktop app integration is unavailable (headless/CI), use service account token flow.

CI / Headless note

For non-interactive use, authenticate with OP_SERVICE_ACCOUNT_TOKEN and avoid interactive op signin. Service accounts require CLI v2.18.0+.
