- Hermes / OpenClaw plugin index.ts now re-export `probeHermesBinary` / `probeOpenClawBinary` and their status types so the dashboard's `runtime-provider-probes.ts` façade can import them via the public package entry instead of deep paths. - Dashboard `package.json` adds `@fusion-plugin-examples/hermes-runtime`, `…/openclaw-runtime`, `…/paperclip-runtime` as workspace deps so pnpm symlinks them into `packages/dashboard/node_modules/`. Without these, the new probe imports failed with "Cannot find module" during `pnpm typecheck`. This clears 6 of the 9 outstanding typecheck errors. The remaining 3 are in the in-flight Hermes plugin rewrite (runtime-adapter still imports from a deleted `./pi-module.js`; the new `index.ts` calls a factory with the wrong arg type) and should be resolved by the same change set that landed the rewrite.

# Hermes Runtime Plugin
|
|
|
|
Drives the local **`hermes` CLI** ([NousResearch/hermes-agent](https://github.com/NousResearch/hermes-agent)) as a subprocess, so a Fusion agent backed by this runtime delegates each prompt to a real Hermes Agent process running on the same machine.
|
|
|
|
## What it does
|
|
|
|
For each `promptWithFallback(session, prompt)` call:
|
|
|
|
1. Spawns `hermes chat -q <prompt> -Q --source tool` (with `--resume <id>` on subsequent calls in the same session).
|
|
2. Captures the trailing `session_id: YYYYMMDD_HHMMSS_xxxxxx` line from stdout.
|
|
3. Strips ANSI + TUI chrome (`╭─ Hermes ─╮`, `↻ Resumed session …`, etc.) and forwards the cleaned response body to `session.callbacks.onText(...)`.
|
|
4. Persists the captured session id on the session object so the next call resumes the same Hermes session.
|
|
|
|
This is fundamentally different from the older "raw-model" approach that bypassed `hermes` entirely by calling `@mariozechner/pi-ai` directly. The CLI subprocess is now the source of truth — provider/model selection, auth, skills, and memory are all the responsibility of the user's local `hermes` install.
|
|
|
|
## Prerequisites
|
|
|
|
You need the `hermes` Python CLI on `PATH` (or set `binaryPath` / `HERMES_BIN`). Install instructions:
|
|
|
|
```bash
|
|
# Recommended: use the upstream installer
|
|
curl -LsSf https://hermes-agent.nousresearch.com/install.sh | sh
|
|
|
|
# Or via pipx (cross-platform)
|
|
pipx install hermes-agent
|
|
```
|
|
|
|
After install, run `hermes login` (or `hermes auth`) to configure a provider. The Fusion plugin does **not** manage Hermes auth — it inherits whatever the local install has.
|
|
|
|
Verify with `hermes --version`.
|
|
|
|
## Limitations
|
|
|
|
Because we drive the CLI's `chat -q` mode:
|
|
|
|
- **No per-token streaming.** Hermes buffers output through prompt_toolkit; the full response arrives once the process exits. `onText` is called exactly once per turn.
|
|
- **No reasoning/thinking deltas.** `-Q` mode suppresses them. If you need streaming + reasoning, switch to Hermes's ACP mode (not yet implemented in this plugin).
|
|
- **No tool-call hooks.** Hermes runs tools internally; Fusion only sees the final assistant text. Use `yolo: true` to skip Hermes's interactive approval prompts in non-interactive sessions.
|
|
- **`AgentRuntimeOptions.cwd`, `tools`, `skills`, `sessionManager`, etc. are ignored** — Hermes's own session/tools/skills systems handle these.
|
|
|
|
## Settings
|
|
|
|
| Key | Env var | Default | Notes |
|
|
|---|---|---|---|
|
|
| `binaryPath` | `HERMES_BIN` | `hermes` | Path to the `hermes` binary. Falls back to PATH lookup. |
|
|
| `model` | `HERMES_MODEL_ID` | (Hermes default) | `-m <model>` (e.g. `claude-sonnet-4-5`, `MiniMax-M2.7`). |
|
|
| `provider` | `HERMES_PROVIDER` | (Hermes default) | `--provider <provider>` — one of `auto`, `anthropic`, `openrouter`, `gemini`, `openai-codex`, `copilot`, `copilot-acp`, `huggingface`, `zai`, `kimi-coding`, `minimax`, `minimax-cn`, `kilocode`, `xiaomi`, `nous`. |
|
|
| `maxTurns` | `HERMES_MAX_TURNS` | `12` | `--max-turns N`. Hermes's own default is 90; we cap lower. |
|
|
| `yolo` | `HERMES_YOLO` | `false` | `--yolo` — skip interactive approval. Required for non-interactive sessions that use shell-style tools. |
|
|
| `cliTimeoutMs` | `HERMES_CLI_TIMEOUT_MS` | `300000` (5 min) | Hard kill on the Fusion side. |
|
|
|
|
Settings precedence: plugin settings → env var → default.
|
|
|
|
## Public API
|
|
|
|
```ts
|
|
import {
|
|
HermesRuntimeAdapter,
|
|
resolveCliSettings,
|
|
invokeHermesCli,
|
|
buildHermesArgs,
|
|
parseHermesOutput,
|
|
probeHermesBinary,
|
|
type HermesCliSettings,
|
|
type HermesCliResult,
|
|
type HermesBinaryStatus,
|
|
} from "@fusion-plugin-examples/hermes-runtime";
|
|
```
|
|
|
|
`probeHermesBinary({ binaryPath?, timeoutMs? })` runs `hermes --version` and returns `{ available, version, binaryPath, reason, probeDurationMs }`. Used by the dashboard's "Runtimes → Hermes" settings card to power the install-status badge.
