Tracepath — I Built an AI Agent Audit Middleware in One Weekend

This is a submission for Weekend Challenge: Passion Edition

What I Built

Tracepath is an open-source middleware that makes any AI agent — LangChain, CrewAI, AutoGen, or your own — auditable, traceable, and compliant with regulations like the EU AI Act and FINRA.

It's a full audit stack you can spin up with a single docker compose up. Every tool call your agent makes gets intercepted, signed with Ed25519, checked against OPA policies, stored in an immutable WORM log, and monitored in real-time for anomalies.

"Can you audit what your agents did yesterday?" — Tracepath answers that.
