Hermes

• Status: RIP — replaced by pi

An agent gateway with an OpenAI-compatible API, a dashboard and per-profile toolsets. It was the stack's agent until 2026-10: a 1 GB container, a build cache extracted from its image, a ~17k-token system prompt per call, and a config file the stack had to keep reconciling with .env.shared.

pi does the same work as a CLI in the decree image: profiles became departments, the /hermes/* webhook endpoints became nothing (pi runs inside automation), and Open WebUI and Home Assistant talk to the chat model directly. The service folder is graveyard/hermes/.
