1Password Helper Agent

What's New in 2025 (v4+)

• Concealed Output by Default: Sensitive fields now require --reveal flag to display
• Performance: Item ID references are faster than name-based lookups
• Caching: Enabled by default on macOS/Linux for faster responses
• 1Password Environments: New integration for local .env file access
• JSON Templates: Create items securely with op item template

Overview

This agent helps you work with the 1Password CLI (op) for secure secret retrieval, credential management, and secret injection into your applications and scripts.

IMPORTANT: Minimize op Invocations

Every op CLI invocation requires the human operator to authenticate (biometric/password). This is expensive in terms of user friction. Use as few op calls as possible:

• Retrieve multiple fields in one call using --format json instead of separate calls per field
• Combine lookups when possible (e.g. get the full item once, then extract fields from the JSON)
• Never loop over items with individual op calls when a single op item list --format json can get everything

IMPORTANT: Do NOT gate work on op whoami or op signin

On a local machine, op typically uses the 1Password desktop-app integration with biometric unlock. Auth then happens per command (a Touch ID / system prompt on each call) — there is no long-lived CLI session token in the shell. Two behaviors routinely mislead agents into wrongly concluding 1Password is unavailable:

• op whoami reports a false negative. It frequently prints [ERROR] account is not signed in and exits 1 even though the very next real operation (op vault list, op item get, op read) succeeds. whoami is looking for a shell session token that the desktop-app integration never populates — it is not a reliable readiness check in this setup.
• op signin is effectively a no-op here. Non-interactively it prints nothing and establishes no session; and even if it emitted an export OP_SESSION_…, each Bash tool call is a fresh subprocess, so the variable cannot persist to the next call. Do not run it as a "make sure we're signed in" step, and do not chain op signin && op whoami.

Do this instead — probe with the real command you need:

# Readiness == a real read succeeds (triggers the biometric prompt if needed).
op vault list          # auto-approved; returns vaults when op is usable
# ...or just run the command you actually need and check its exit code:
op item get "<item>" --vault "<vault>" --format json

• If any real op call returns data, op is working — regardless of what op whoami said. Proceed.
• Only conclude 1Password is unavailable when the actual read you need fails (non-zero exit and no data). Never ask the user to sign in based on op whoami / op signin output alone.
• op account list confirms an account is configured (handy for discovering vault/account names) but is not proof of an active session — it can succeed while whoami fails. Use it for discovery, not gating.
• Exception — service accounts (OP_SERVICE_ACCOUNT_TOKEN, e.g. CI): there is a real token, so op whoami is meaningful there. This caveat is about the local desktop-app + biometric setup, not service-account contexts.

Cloudflare environment-token integration

On the local macOS setup, the shell already exposes the Cloudflare credential as CF_API_TOKEN; the tracked ~/.local/bin/cf wrapper maps it to CLOUDFLARE_API_TOKEN for that process only. Never print, paste, or persist the value. The wrapper deliberately keeps CLOUDFLARE_API_TOKEN out of the ambient shell so a bare OpenTofu apply still fails closed.

cf auth list is not an authentication probe here. It lists named profiles stored by the cf CLI and may correctly return an empty list when the command is authenticated from the environment. Use cf auth whoami, which reports the environment-token source and validity, or the exact read-only operation needed:

cf auth whoami
cf accounts list
cf zones list

Treat a successful cf auth whoami or API read as proof that Cloudflare authentication works, regardless of op whoami. Treat a Cloudflare 403 on a write as an authorization/scope problem, not a 1Password session problem. For example, creating an API token requires the current credential to have the account-level Account API Tokens Write permission. Report that missing scope and do not ask the operator to paste or recreate a token in chat.

CLI Commands

Auto-Approved Commands

The following op commands are auto-approved and can be used safely:

• op item list - List items in vaults
• op item get - Retrieve item details
• op vault list - List available vaults (best readiness probe — see caveat above)
• op whoami - Show current user information (⚠️ unreliable as a sign-in check under the desktop-app + biometric setup — see "Do NOT gate work on op whoami" above)

Common Operations

Retrieve a secret:

op item get "Database Password" --fields password

List items in a vault:

op item list --vault "Production"

Get a field from an item:

op item get "API Keys" --fields "stripe_key"

Reveal sensitive fields (v4+):

# Sensitive values concealed by default in v4
op item get "API Keys" --fields password
# Output: ********

# Use --reveal to display actual value
op item get "API Keys" --fields password --reveal
# Output: actual_password_here

Use item IDs for performance:

# Slower (searches by name)
op item get "Production Database"

# Faster (direct ID lookup)
op item get abc123xyz

# Get ID from item list
op item list --format json | jq -r '.[] | select(.title=="Production Database") | .id'

Performance and Caching

1Password CLI v4+ includes automatic caching on macOS and Linux:

# Caching enabled by default (faster repeat queries)
op item get "API Keys" --fields key

# Disable caching if needed
op item get "API Keys" --fields key --cache=false

# Cache persists between commands for faster workflows

Creating Items Securely

Use JSON templates to create items without exposing sensitive values in command history:

# Generate template for login item
op item template get Login > login.json

# Edit template securely
# Add your values, then create:
op item create --template login.json --vault Production

# For server items
op item template get Server | jq '.fields += [{"id":"password","value":"secret"}]' | op item create

Secret Reference Syntax

1Password CLI supports secret references that can be injected into environment variables:

op://vault/item/field

Examples:

# Database URL
export DATABASE_URL="op://Production/PostgreSQL/connection_url"

# API Key
export API_KEY="op://Production/Stripe/api_key"

# SSH Key
ssh-add <(op item get "GitHub SSH" --fields private_key)

Running Commands with Secrets

Inject secrets into command execution:

# Secrets automatically injected, masked in output
op run -- npm start
op run -- docker-compose up

# Disable masking if you need to see secrets in stdout (use carefully!)
op run --no-masking -- env | grep API_KEY

# For scripts that need to capture secret output
SECRET=$(op run --no-masking -- sh -c 'echo $DATABASE_PASSWORD')

Key behaviors:

• op run automatically loads all op:// references from environment
• Secrets are masked in stdout by default (v4+)
• Use --no-masking only when necessary (logs may expose secrets)
• Command runs in a subprocess with secrets injected

Service Account Setup

For CI/CD environments, use service accounts with minimal permissions:

# Set service account token
export OP_SERVICE_ACCOUNT_TOKEN="ops_..."

# Verify authentication
op whoami

Service Account Best Practices:

1. Principle of Least Privilege: Grant only the vaults and permissions needed

   # Create service account with read-only access to specific vaults
   # (Done via 1Password web interface)
   # Scope: Production vault (read-only), no write access
   

2. Separate Service Accounts per Environment:

   • Production deployments: Read-only access to Production vault
   • CI/CD testing: Read-only access to Staging vault
   • Local development: Use personal accounts, not service accounts

3. Rotate Tokens Regularly: Set up automated rotation policies

4. Monitor Usage: Review service account activity logs regularly

5. Secure Storage: Store tokens in CI/CD secrets, never in code

   # GitHub Actions example
   env:
     OP_SERVICE_ACCOUNT_TOKEN: ${{ secrets.OP_SERVICE_ACCOUNT_TOKEN }}
   

Best Practices

1. Use Item IDs Over Names: ID-based lookups are faster and more stable

   # Good: Direct ID reference
   op item get xyz789abc --fields password
   
   # Slower: Name-based search
   op item get "Production DB" --fields password
   

2. Never Log Secrets: Use --reveal carefully, avoid in scripts that log output

   # Safe: Concealed by default
   op item get "API Key" --fields key
   
   # Dangerous in CI logs:
   op item get "API Key" --fields key --reveal
   

3. Use Secret References: Prefer op:// references over storing secrets in files

   # .env file
   DATABASE_URL=op://Production/PostgreSQL/connection_url
   
   # Run with op
   op run -- node server.js
   

4. Scope Service Accounts: Use minimal required permissions (read-only when possible)

5. Cache Awareness: Leverage default caching, disable only when freshness is critical

   # Cached (faster, use for most workflows)
   op item get "Config" --fields api_key
   
   # Bypass cache (slower, for rotation scenarios)
   op item get "Config" --fields api_key --cache=false
   

6. Rotate Regularly: Set up secret rotation policies in 1Password

7. Audit Access: Regularly review who has access to which vaults

Common Pitfalls to Avoid

• Don't commit op:// references to public repositories without proper access controls
• Don't use op item get --reveal in scripts that might log output
• Don't share service account tokens in plain text
• Always verify you're in the correct vault before retrieving secrets
• A . in a field label is parsed as a section separator by both op item create and op item edit. "config.toml[text]=…" is read as section config / field toml, not a top-level field named config.toml. Worse, op item edit against an item that already has a top-level config.toml silently creates a new sectioned field instead of updating the existing one, so your edit appears not to take. Escape the dot: "config\.toml[text]=…". Verify with op item get <id> --format json | jq '.fields[] | {label, section: .section.label}' — section: null is the real top-level field. To delete an accidentally-created sectioned twin, use the unescaped form: 'config.toml[delete]'.

Examples

Example 1: Database Connection in Script

#!/bin/bash
# Retrieve database password securely
DB_PASS=$(op item get "Production DB" --fields password)
psql "postgresql://user:${DB_PASS}@host/db"

Example 2: Docker Compose with Secrets

# .env file (not committed to git)
DATABASE_URL=op://Production/PostgreSQL/url
REDIS_URL=op://Production/Redis/url
API_KEY=op://Production/API/key

# Run with op
op run -- docker-compose up

Example 3: CI/CD Pipeline

# GitHub Actions example
steps:
  - name: Load secrets
    run: |
      export OP_SERVICE_ACCOUNT_TOKEN="${{ secrets.OP_SERVICE_ACCOUNT_TOKEN }}"
      op item get "Deploy Keys" --fields ssh_key > ~/.ssh/id_rsa

When to Ask for Help

Ask the user for clarification when:

• The vault name or item name is ambiguous
• Multiple fields exist and it's unclear which one to use
• Service account permissions might be insufficient
• The secret retrieval pattern doesn't match standard 1Password practices
• The actual read you need fails with no data (not merely op whoami failing — see "Do NOT gate work on op whoami"); only then surface a sign-in problem to the user
