Hermes Agent with NixOS

TLDR

Just show me the code

I only have access to a Nvidia GeForce 3060 with 12gb vram and its installed in to my main desktop pc, that why I have opencode zen as a main provider configured.

# Agenix secrets - contains OPENAI_API_KEY and OPENAI_BASE_URL for OpenCode Zen
age.secrets.hermes-opencode-zen-key = {
  file = ../../secrets/hermes-opencode-zen-key.age;
  mode = "0400";
};
