Developer creates open-source proxy tool to prevent AI agents from degrading in quality and justify expensive subscription costs

3 Key Points

  1. Rigor is an anti-enshittification proxy designed for OpenAI Code and Claude Code instances to maintain agent quality over time

  2. Uses an epistemic graph with LLM-as-judge evaluation to assess AI agent performance and prevent quality degradation

  3. Addresses user frustration with expensive AI agent subscriptions (around $200) by providing performance accountability

  5. Team plans to release the open-source core once initial waitlist users are onboarded
