Run Hermes on an Antigravity subscription via the official agy CLI (DirectSDK path). Streams tokens progressively, persists multi-turn trajectories via agy --conversation (up to 239k tokens), discovers models dynamically per account, maps thinking effort, reports quota in /usage, and aborts reported native tools.

## Good to know before installing

Routes inference and /usage quota reads through Google's official agy CLI under your subscription (usage counts against it); links (symlink, else hardlink/copy) the antigravity-oauth-token into a per-session private temp HOME deleted on close; probes OS keyring presence (Linux Secret Service, macOS Keychain, Windows Credential Manager) without reading secrets; on macOS symlinks ~/Library/Keychains for CLI session reuse; never writes to vendor credential stores; strips credential-looking environment variables before spawning agy (name heuristic; ANTIGRAVITY_ENV_STRICT for an allow-list). Disclosure — the opt-in ANTIGRAVITY_DEBUG_PROMPT_DIR env var writes every outgoing prompt (full conversation text) to that directory.

## 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 antigravity-subscription-directsdk
```

2. Said no? Turn it on later:

```bash
hermes plugins enable antigravity-subscription-directsdk
```

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
