Agent Skills: 1Password CLI

1Password CLI

Manage personal secrets and passwords using the 1Password CLI (op).

CRITICAL RULES

1. Tag Filter: Only read secrets that have the agents tag. All queries MUST include --tags agents filter.
2. Confirmation Required: Always confirm with the user before creating or modifying secrets. No confirmation is needed for reading secrets.

Prerequisites

Before using any op commands, ensure:

1. 1Password CLI is installed (op --version)
2. Desktop app integration is enabled (Settings > Developer > Integrate with 1Password CLI)
3. User is signed in (run any command to trigger authentication)

Common Operations

List Items

List items tagged for agent access:

op item list --tags agents

List items by category:

op item list --tags agents --categories Login
op item list --tags agents --categories Password
op item list --tags agents --categories "API Credential"

List items in a specific vault:

op item list --tags agents --vault Personal

Get Item Details

Get full details for an item:

op item get "Item Name" --tags agents

Get specific fields:

op item get "GitHub Token" --tags agents --fields label=username,label=password

Get in JSON format:

op item get "API Key" --tags agents --format json

Get one-time password (OTP):

op item get "Google" --tags agents --otp

Read Secret Values

Use op read with secret references for direct value retrieval:

op read "op://Personal/GitHub Token/password"
op read "op://Personal/API Key/credential"

Secret reference format:

op://vault-name/item-name/[section-name/]field-name

Create Items

ALWAYS confirm with user before creating items.

Create a Login item:

op item create --category=login \
  --title='Service Name' \
  --vault='Personal' \
  --url='https://example.com' \
  --tags='agents' \
  username='user@example.com' \
  password='secure-password'

Create an API Credential:

op item create --category="API Credential" \
  --title='Service API' \
  --vault='Personal' \
  --tags='agents' \
  credential='api-key-value'

Create a Password item:

op item create --category=password \
  --title='Database Password' \
  --vault='Personal' \
  --tags='agents' \
  password='secure-password'

Create with auto-generated password:

op item create --category=login \
  --title='New Service' \
  --vault='Personal' \
  --tags='agents' \
  --url='https://example.com' \
  --generate-password='letters,digits,symbols,32' \
  username='user@example.com'

Edit Items

ALWAYS confirm with user before editing items.

Edit a field value:

op item edit 'Service Name' 'password=new-password'

Add or update tags (preserving the agents tag):

op item edit 'Service Name' --tags='agents,production,api'

Generate new password:

op item edit 'Service Name' --generate-password='letters,digits,symbols,32'

Delete Items

ALWAYS confirm with user before deleting items.

Delete an item:

op item delete "Old Service"

Archive instead of delete:

op item delete "Old Service" --archive

Output Formats

Human-readable (default):

op item get "Service Name"

JSON format (for parsing):

op item get "Service Name" --format json

Parse with jq:

op item get "Service Name" --format json | jq '.fields[] | select(.label=="password") | .value'

Common Patterns

Find all agent-accessible secrets

op item list --tags agents --format json | jq -r '.[] | "\(.title) (\(.vault.name))"'

Get password for a service

op item get "Service Name" --tags agents --fields label=password --format json | jq -r '.fields[0].value'

Check if an item exists

op item get "Service Name" --tags agents --format json &>/dev/null && echo "exists" || echo "not found"

List all API credentials for agents

op item list --tags agents --categories "API Credential"

Categories

Available item categories:

• API Credential
• Bank Account
• Credit Card
• Database
• Document
• Driver License
• Email Account
• Identity
• Login
• Membership
• Outdoor License
• Passport
• Password
• Reward Program
• Secure Note
• Server
• Social Security Number
• Software License
• Wireless Router

Error Handling

If authentication fails:

op signin

If item not found, verify:

1. Item exists in 1Password
2. Item has the agents tag
3. Correct vault is accessible
4. User is properly authenticated

Best Practices

1. Always use the agents tag for items intended for agent access
2. Confirm destructive operations (create, edit, delete) with user
3. Use secret references (op://...) when injecting secrets into commands
4. Prefer JSON format when parsing output programmatically
5. Use item IDs instead of names for more reliable references
6. Specify vault when dealing with multiple vaults to avoid ambiguity
