I built an AI agent that diagnoses cars — and asks before it touches anything

Built for the TrueForge Agent Harness Hackathon (Aug 24–30, 2026).

"Something expensive broke. Figure out why and prove it. Ask a human before you touch anything."

That was basically the idea behind FaultTrace.

I wanted to build something that felt more like an actual investigation than another chatbot with a few tools attached. The result is an autonomous vehicle-forensics agent that can gather evidence, test competing explanations, run actual analysis, and stop when it reaches a physical-world action that needs a human.
