zeno-secrets-1password

1Password-backed SecretsStore for Zeno.

Ships OpCliSecretsStore, a SecretsStore adapter that reads secrets through the 1Password CLI (op read). Intended for agents that run in environments where a 1Password service-account token is available but mounting the raw secret material into the process env is undesirable.

Install

uv add 'zeno-framework[secrets-1password]'

Install the 1Password CLI on the host:

brew install 1password-cli       # macOS
# or follow https://developer.1password.com/docs/cli/get-started/

Export a service-account token:

export OP_SERVICE_ACCOUNT_TOKEN="ops_..."

Usage

from zeno.app import ZenoApp
from zeno.secrets_1password import OpCliSecretsStore

app = ZenoApp(
    ...,
    secrets=OpCliSecretsStore(
        references={
            "OPENAI_API_KEY": "op://Engineering/openai/credential",
            "STRIPE_KEY":     "op://Engineering/stripe/api_key",
        },
        cache_ttl=60.0,
    ),
)

Inside a tool:

@tool
async def call_stripe(ctx: Ctx) -> str:
    api_key = await ctx.secrets.get("STRIPE_KEY")
    ...

What it does

• get(name) — if name begins with op://, invokes op read name directly; otherwise looks up the reference in the references map and shells op read <ref>.
• Results are cached in-process for cache_ttl seconds (default 60). Pass cache_ttl=None to disable caching.
• Invocations time out at timeout seconds (default 5). The subprocess is killed and reaped on timeout; no ResourceWarning leaks.
• OP_SERVICE_ACCOUNT_TOKEN is passed to the subprocess via an explicit env dict that inherits only PATH — unrelated parent env vars are not leaked into the op process. Pass token="ops_..." to the constructor to override the env var.
• Missing op binary → ConfigurationError with an install pointer.
• Missing token → ConfigurationError raised before the subprocess runs.
• op read exit codes are inspected: "item not found" / "no such" / "isn't an item" map to SecretNotFoundError; everything else (auth failures, network errors) maps to SecretsBackendError with the stderr text preserved in the message.

Why op CLI, not the Connect HTTP API?

The CLI path works both locally (via 1Password desktop auth) and in CI (via a service-account token) with no Connect server to self-host. Connect-based and SDK-based stores can ship later as sibling classes inside the same package without breaking existing callers.

Part of the Zeno framework.
