  1Password CLI (`op`) usage patterns: reading secrets, extracting SSH keys,
  handling sensitive field blocking with --reveal workarounds.

# 1Password CLI (`op`)

Use `op` (v3+) to read secrets from 1Password during agent sessions. All outputs should avoid leaking secrets into logs/chat.

## Authentication

1Password CLI integrates via the 1Password app (`op signin`) or service account tokens. Verify status with:

```bash
op whoami    # Shows account URL + integration ID
```

### Session Token Pattern (`op signin --raw`)

For scripted use, capture the session token directly:

```bash
export OP_SESSION="$(op signin --raw 2>&1)"
# Now all subsequent op commands use this session
op item list --vault Hermes
```

This avoids the interactive eval pattern and works in non-interactive shells.

## Reading Items

### Basic item retrieval
```bash
# Human-readable output
op item get 'ITEM_TITLE' --vault 'VAULT_NAME'

# JSON (for programmatic parsing)
op item get 'ITEM_TITLE' --vault 'VAULT_NAME' --format json
```

### Reading specific fields
```bash
# String fields (works directly — no restrictions)
op item get 'ITEM' --field 'field_label'

# Sensitive fields (passwords, private keys, tokens)
# These are BLOCKED when piped or redirected:
op item get 'ITEM' --field 'Sensitive-Field'    # Returns "[use 'op item get ID --reveal' to reveal]"
```

## ⚠️ Pitfall: Sensitive Field Extraction Blocked

The 1Password CLI **blocks direct output** of sensitive fields (SSH keys, passwords, tokens) when piped, redirected, or captured. This is a security feature, not a bug.

**Workarounds:**

| Method | Command | Notes |
|--------|---------|-------|
| `--reveal` | `op item get ITEM --reveal --field 'Field-Name'` | Outputs the actual value (may include wrapping quotes) |
| `--reveal --value` | `op item get ITEM --reveal --field 'Field-Name' --value` | Strips quotes, raw value only |
| Temp file | `op item get ITEM --reveal --field 'Field' > /tmp/file` | Write to file, then `cat` or use via tool |

### SSH Key Extraction Pattern

```bash
# SSH keys are always TYPE:SSHKEY in 1Password
tmpkey=$(mktemp /tmp/op_ssh_key_XXXX)
op item get 'SSH-KEY-NAME' --vault 'VaultName' --reveal --field 'Private-Key' --value > "$tmpkey" 2>/dev/null
chmod 600 "$tmpkey"
# Then use: eval "$(ssh-agent)" && ssh-add "$tmpkey"
# Or: ssh -i "$tmpkey" user@host
```

After use, clean up: `rm -f "$tmpkey"`

### SSH Key JSON Parse

```bash
# Get full SSH key item as JSON, parse the openssh format
op item get 'SSH-KEY-NAME' --vault 'Vault' --reveal --format json | python3 -c "
import sys, json
data = json.load(sys.stdin)
for f in data.get('fields', []):
    if 'private' in f.get('label','').lower() or f.get('id') == 'private_key':
        print(f.get('value', ''))
"
```

Note: If `--reveal` still returns `[REDACTED]` in openssh format, the session may need refresh. Re-signin with `op signin` may be required.

## Useful Commands

```bash
# Search items
op item list --vault 'VaultName'
op item search 'keyword'

# List vaults
op vault list

# Service account (non-interactive)
op connect server CONNECT_URL
op connect service-account --account ACCOUNT_ID --secret TOKEN
```

### ⚠️ Service Account `--vault` Requirement

When authenticated as a **service account**, `op item get` REQUIRES `--vault`:

```bash
# FAILS: "a vault query must be provided when this command is called by a service account"
op item get <ITEM_ID> --fields credential

# WORKS: explicit --vault
op item get <ITEM_ID> --vault Hermes --fields label=credential --reveal
```

### API_CREDENTIAL Item Type

HA API tokens stored as `API_CREDENTIAL` category have a `credential` field:

```bash
# Extract API credential (requires --reveal for concealed field)
TOKEN=$(op item get <ITEM_ID> --vault Hermes --fields label=credential --reveal)
```

### `--fields` Syntax

```bash
# By field label (preferred — robust against ID changes)
op item get ITEM --fields label=credential --reveal
op item get ITEM --fields label=username,label=password --reveal

# By field type
op item get ITEM --fields type=concealed --reveal

# Multiple fields as CSV
op item get ITEM --fields label=username,label=password --format json
```

## Common Field Types

```
STRING    → Direct output works (hostnames, usernames, URLs without passwords)
PASSWORD  → Requires --reveal
SSHKEY    → Requires --reveal + file redirect for private key usage
NOTES     → --field 'notesPlain'
```

## Creating Items with Custom Fields

`op item create` supports arbitrary custom fields via `key=value` syntax:

```bash
# Login item (username + password)
op item create --title="app-db" --vault "$VAULT_ID" \
  --category=Login \
  username=appuser password="$(openssl rand -base64 32)"

# Password item with multiple custom fields
op item create --title="app-security" --vault "$VAULT_ID" \
  --category=Password \
  password="$PRIMARY_SECRET" \
  "internal_token=$TOKEN1" \
  "jwt_secret=$TOKEN2" \
  "secret_key=$TOKEN3" \
  "lfs_jwt_secret=$TOKEN4"
```

Custom fields appear as labeled fields in the 1P item and are retrievable via `op item get --fields field_name`.

## ⚠️ Pitfall: API Credential Item Creation — Two-Step Required

When creating an `API Credential` item, `op item create` does NOT
populate the `credential` (token) field even when passing
`credential=VALUE` as a parameter. The item is created with `username`
and `url` populated, but the `credential` field stays empty.

**Two-step required:**

```bash
# Step 1: Create the item (username + url are set, credential is NOT)
op item create --category="API Credential" \
  --title="My API Token" --vault="Hermes" \
  username="myuser" url="https://api.example.com"

# Step 2: Edit to set the credential field
op item edit "<ITEM_ID>" --vault="Hermes" \
  credential="ACTUAL_TOKEN_VALUE"
```

**Contrast with Login category:** `op item create --category="Login"`
correctly populates both `username` and `password` in a single step —
the two-step issue is specific to the `API Credential` category.

```bash
# This works in one step (Login category):
op item create --category="Login" \
  --title="My Service" --vault="Hermes" \
  username="admin" password="s3cret" --url="https://service.example.com"
```

**Verification:**
```bash
op item get "<ITEM_ID>" --vault "Hermes" --fields credential --reveal
# Should output the actual token value
```

## ⚠️ Accessing Vaults Outside Local Service Account Scope

The local `op` service account may only have access to certain vaults (e.g. "Hermes"). Other vaults (e.g. "Kubernetes ESO" used by External Secrets Operator in K8s) are invisible:

```bash
op vault list
# ID                            NAME
# 5ythsz37hf3xminhq33drg55tm    Hermes
# "Kubernetes ESO" NOT listed
```

### Workaround: Use the ESO Service Account Token

Extract the ESO token from K8s and use it as `OP_SERVICE_ACCOUNT_TOKEN`:

```bash
# Get ESO token from K8s secret
ESO_TOKEN=$(kubectl get secret onepassword-token -n external-secrets \
  -o jsonpath="{.data.token}" | base64 -d)

# Use it for op commands
OP_SERVICE_ACCOUNT_TOKEN="$ESO_TOKEN" op vault list
# ID                            NAME
# 334ykdtj5kar3jlpcrztjvx2fu    Kubernetes ESO

# Now create/read items in that vault
OP_SERVICE_ACCOUNT_TOKEN="$ESO_TOKEN" \
  op item create --title="app-db" --vault "334ykdtj5kar3jlpcrztjvx2fu" ...
```

⚠️ **Vault NAME may not resolve with service accounts.** Use the vault ID (e.g. `334ykdtj5kar3jlpcrztjvx2fu`) instead of the name ("Kubernetes ESO") — service accounts sometimes can't resolve vault names, only IDs.
