Proton Pass secret source: resolves pass://vault/item/field references (mapped source "protonpass") or every env-var-titled item of one vault (bulk source "protonpass_vault") into environment variables at startup through the user's own pass-cli, beside the built-in Bitwarden and 1Password sources, with a hermes protonpass setup/status/token/set/remove/sync/disable CLI. Stdlib-only, no Python deps.

## Good to know before installing

When enabled, runs the user-installed pass-cli (argv only, allowlisted env, 30 s per call), which talks to Proton's API; a personal access token or AI-agent token is read from Hermes' env and passed only to the pass-cli login child's environment (never argv); writes a 0700 session dir under cache/protonpass and a 0600 value cache (cache_ttl_seconds: 0 disables); no self-update, no downloaded binaries, no telemetry, no background process.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install protonpass
```

2. Said no? Turn it on later:

```bash
hermes plugins enable protonpass
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
