Central AI Hub

One small service that every way in reaches every ability through. Built once, shared by the phone app, the house voice, chat, and the admin app.

Demonstrated Skills & Tech Stack

• Core Technologies: Go 1.25 service · HTTP JSON API · MQTT · LLM intent routing · OmniRoute gateway · Docker
• Key Tools: Jervis (voice) · Home Assistant · Paperclip · Artemis · internet use control · Apprise / NTFY · OmniRoute
• Engineering Capabilities: service design · intent routing · authorization and approval flows · event-driven integration · deterministic safety for high-consequence actions

Quick Start

# Phase 1 — prove the Paperclip round trip
# 1. Create an agent API key in Paperclip.
# 2. Export it for the test only.
export PAPERCLIP_API_KEY=<redacted>
# 3. File one job.
curl -s -X POST http://192.168.20.13:3100/api/issues \
  -H "Authorization: Bearer $PAPERCLIP_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"title":"round-trip test","description":"prove the return path"}'

Usage & Configuration

• Model calls go through OmniRoute at http://192.168.20.13:20129/v1.
• Secrets come from ~/.config/environment.d/10-secrets.conf.
• Paperclip is at http://192.168.20.13:3100. An API key is required.
• Home Assistant is at http://192.168.20.30:8123.
• Jervis (voice) is at http://192.168.20.13:8501.
• Hub is at http://192.168.20.13:8788 (local Docker container).

The design brief is hub_brief.md. Project instructions are AGENTS.md.

The interface between the Hub and every data project is docs/ask-contract.md. The frozen inbound API (ways in to the Hub) is docs/hub-api.md. Every other project is a peer, not a sub-project. A high-consequence control (for example, cutting the kids' internet) does not route through the Hub.
