Hermes Runtime Plugin
Provides an executable Hermes runtime plugin for Fusion. This package enables runtime registration, discovery, and session execution so agents configured with runtimeConfig.runtimeHint: "hermes" can run through the standard runtime adapter contract.
Overview
This plugin follows the runtime adapter pattern used by other executable plugin runtimes:
- Registers Hermes runtime metadata for resolver discovery
- Creates executable runtime sessions via
createFnAgent - Delegates prompt execution through
promptWithFallback - Exposes model descriptions through
describeModel - Supports best-effort session disposal via
dispose()
