Configure Hermes Agent to use MandAPI as a custom OpenAI-compatible Chat Completions endpoint. Inspect the installed version and existing model settings, preserving unrelated options. Use model.provider=custom, model.base_url=https://api.mandapi.com/v1, the exact account-visible MODEL_ID and model.key_env=MANDAPI_API_KEY, or use the current hermes model wizard. Keep the key private and ensure the launched process inherits it. Do not use old LLM_MODEL configuration. Guide one short text check and then a read-only README task, reviewing MandAPI usage. Explain how to restore the prior model settings.
