built an open-source reliability layer for AI agents , three tools, all live, zero infrastructure cost

Over the last few months I identified three problems that every developer building AI agents hits in production - and built a standalone open-source tool for each one. Together they form the Thread Suite. The Problem Space When you deploy an AI agent to production, you face three specific failure modes: Failure Mode 1 - Structural corruption Your agent returns conversational text instead of JSON. Or missing fields. Or wrong types. Your database gets dirty data. Failure Mode 2 - Behavior drift Your agent starts behaving differently across runs. Hallucinating. Refusing.
