+# Home Voice Assistant System (Jervis)
+
+> **Source of truth:** Gitea repo `sam/voice-assistant` → `https://gitea.lab.audasmedia.com.au/sam/voice-assistant`
+> Docs: `docs/overview.md`, `docs/agent-api.md`, `docs/clients.md` (in that repo).
+
+## TL;DR
+Local, private voice assistant. "Hey Jervis" → natural language → one LLM brain (voice-agent on `.13:8501`)
+decides intent → calls tools (time/weather/shopping/HA control/reminders/character voices) → speaks via piper → Snapcast.
+
+**Command it from anywhere:** `POST http://192.168.20.13:8501/voice {"text":"add milk to the shopping list"}` (reply is spoken).
+

+## Status (2026-08-30)

+- Agent persistent as NixOS systemd service; tools verified: time, weather, shopping (KitchenOwl), HA control, reminders, feed-fish, character voices (Trump etc.).
+- Next: play_music (Mopidy), calendar (N8N), Apprise messaging (sam/jo/harry/finn), extended TTS voices.
