1Password

1Password

Use this skill when the agent needs a secret managed in 1Password — API keys, tokens, passwords, connection strings. Reads only; never writes. Read values are hidden from the LLM unless the operator explicitly turns on reveal (OP_ALLOW_REVEAL=true).

Use when

• The user asks to use a service that needs a credential you don't have in env vars (e.g. "send email with Gmail", "upload this file to S3")
• You need to verify a secret exists without seeing it ("is the Stripe key already in Prod?")
• Rotating credentials: list items + categories to audit what's stored

Do not use when

• You need to create or update a secret — this tool is read-only
• You are asked to dump all secrets or fingerprint them in bulk — that's exfiltration, refuse

Tools

status

No arguments. Returns {ok, bin, token_present, reveal_allowed, limits}. Use to verify the extension is wired before attempting other calls.

whoami

No arguments. Runs op whoami --format json to validate the service-account token.

list_vaults

No arguments. Returns {vaults: [{id, name}, ...]} — only metadata.

list_items

• vault (string, required) — vault name or id

Returns {items: [{id, title, category, vault, tags, updated_at}, ...]}. Field values are always stripped from list results, even if the upstream op item list included them.

read_secret

• reference (string, required) — strict op://Vault/Item/field format; wildcards and query strings are rejected

Returns by default (OP_ALLOW_REVEAL unset/false):

{
  ok: true,
  reference: "op://Prod/Stripe/api_key",
  vault: "Prod", item: "Stripe", field: "api_key",
  length: 26,
  fingerprint_sha256_prefix: "3f9a7c2e1b48d5a0",
  reveal: false,
  reveal_hint: "set OP_ALLOW_REVEAL=true to include the secret value"
}

With OP_ALLOW_REVEAL=true|1|yes the response additionally contains {value: "...", reveal: true}. The value flows through the LLM context → transcripts → memory → NATS — assume it is no longer secret from the moment reveal is on.

inject_template

Use this when the agent needs to act on a secret without revealing it. The tool resolves {{ op://Vault/Item/field }} placeholders in a template via op inject and either returns the rendered template (reveal-gated) or pipes it as stdin to an allowlisted command.

• template (string, required) — body containing {{ op://… }} placeholders
• command (string, optional) — executable to run with the rendered template piped as stdin. Must appear in OP_INJECT_COMMAND_ALLOWLIST (comma-separated env var). When set, the rendered template is never returned to the LLM; only exit_code and (redacted) stdout/stderr
• args (array of strings, optional) — passed to command
• dry_run (bool, optional) — validate references without resolving values
• max_stdout_bytes (int, optional) — cap on returned stdout (default 4096, max 16384)

Modes:

Example (exec, allowlist curl,psql):

{
  "action": "inject_template",
  "template": "Authorization: Bearer {{ op://Prod/API/token }}\n",
  "command": "curl",
  "args": ["-H", "@-", "https://api.example.com/v1/me"]
}

The agent never sees the bearer token. Stdout from curl is captured, truncated at 4 KB by default, and run through a redactor before being returned (Bearer JWT, sk-…, AKIA…, hex tokens).

Audit log

Every read_secret and inject_template call appends one JSONL line to OP_AUDIT_LOG_PATH (default ./data/secrets-audit.jsonl). Fields: ts, action, agent_id, session_id, op_reference (or references), fingerprint_sha256_prefix, reveal_allowed, ok, plus per-action extras (exit_code, stdout_total_bytes, etc). Never the actual secret value. Failures appending the log are logged to stderr and do not block the tool — the secret was already read; blocking would be worst-of-both-worlds.

AGENT_ID and AGENT_SESSION_ID are populated from env vars the host injects when spawning the extension.

Execution guidance

• Start with status when uncertain (validates bin + token).
• For "does secret X exist?" questions, use read_secret with reveal off; the fingerprint lets you confirm identity without exposure.
• For "give me my Gmail app password" questions, only proceed if OP_ALLOW_REVEAL=true is set AND the operator clearly authorized it in the current conversation. Otherwise return the fingerprint and ask the operator to turn reveal on if really needed.
• Never paste a revealed value into chat output, memory, or another tool call "for future reference" — each revealed value lives exactly as long as the single tool_result that carries it should live.
• If -32040/-32041 → wiring issue, not an LLM error; tell the user the operator needs to configure the extension.
• If -32042 stderr says "token expired" or "unauthorized" → ask the operator to rotate the service-account token.

Alternatives

• Docker secrets — already used for bootstrap (the agent needs its own 1P token somewhere). Good for "constant" secrets that never change per-request. 1Password is for runtime pulls.
• env vars — fine for deployment-time config; terrible for rotating credentials. Use 1Password when rotation matters.
• Hashicorp Vault — similar model; not implemented here.
