building a digital doorman

A lightweight AI agent that answers questions about my work by reading actual code. Architecture, security, and model selection decisions.

The model used is a Claude model, not self-hosted, so I'm not sure why the infrastructure is at all relevant here, except as click bait?
Meh it's kind of interesting. Even if it is just a ridiculously over engineered agent orchestrator for a chat box and code search
