Resolve provider credentials from 1Password op://vault/item/field references
at startup via the official `op` CLI, alongside the existing Bitwarden source.
Users map env-var names to references in secrets.onepassword.env; after .env
loads, each is resolved with `op read` and injected into os.environ. Auth is
whatever `op` already uses (service-account token or desktop/interactive
session) — Hermes never authenticates or installs `op` itself.
Startup-safe and fail-open: a missing binary, expired auth, a bad reference,
or an empty value each warn and fall back to existing credentials, never
blocking startup. Successful, complete pulls are cached in-process and on disk
(<hermes_home>/cache/op_cache.json, 0600) via the shared DiskCache; only
secret values are stored, never the token (auth is fingerprinted into the
key). Adds `hermes secrets onepassword {setup,status,set,remove,sync,disable}`
(aliases op/1password), config defaults, the cli-config example, docs, and
hermetic tests.
Hardening applied across both backends in env_loader: each source runs in its
own guard, config sections are coerced to dict, and cache_ttl_seconds is
coerced defensively — so a malformed secrets: section can't abort startup.

Secrets
Hermes can pull API keys from external secret managers at process startup instead of storing them in ~/.hermes/.env. The bootstrap token for the secret manager lives in .env; every other provider key (OpenAI, Anthropic, OpenRouter, etc.) can stay in the manager and rotate centrally.
Supported:
- Bitwarden Secrets Manager —
bwsCLI, lazy-installed, free tier works. - 1Password —
op://references via the officialopCLI; service-account or desktop session auth.
Multiple sources at once
You can enable more than one secret source at the same time — for example a team Bitwarden project alongside a personal vault plugin. Sources compose per env var with a deterministic precedence ladder:
- Your
.env/ shell wins by default. A source only replaces a pre-existing value when its ownoverride_existing: trueis set (Bitwarden defaults to true so central rotation works). - Mapped sources beat bulk sources. A source where you explicitly bind env vars to references (an
env:map) outranks a source that injects a whole project of secrets implicitly, regardless of ordering. - First source wins. Within the same shape, the order of the optional
secrets.sourceslist (or registration order) decides. Later claims on an already-claimed var are skipped — with a startup warning, never silently.
override_existing never lets one source overwrite a var another source already claimed, and no source can ever overwrite another source's bootstrap token (e.g. BWS_ACCESS_TOKEN).
secrets:
sources: [bitwarden] # optional explicit ordering
bitwarden:
enabled: true
project_id: "..."
Every credential injected by a source is labelled with its origin — setup flows and hermes model show (from Bitwarden) next to detected keys so you always know where a value came from.
Adding your own backend
Third-party secret managers ship as standalone plugins, not core PRs. A backend subclasses agent.secret_sources.base.SecretSource (one required method: fetch(cfg, home_path) -> FetchResult) and registers via ctx.register_secret_source(MySource()) in the plugin's register(ctx). The orchestrator owns precedence, conflict handling, timeouts, and provenance — your source only fetches. Contract rules: fetch() never raises, never prompts, and returns within its timeout budget; validate your implementation against the conformance kit in tests/secret_sources/conformance.py.
The bundled set is deliberately closed (same policy as memory providers): Bitwarden and 1Password ship in-tree. Everything else — Infisical, Proton Pass, HashiCorp Vault, AWS Secrets Manager, OS keystores — belongs in plugin repos; share them in the Nous Research Discord (#plugins-skills-and-skins).
