StateFabric adds durable, inspectable state to AI agents by storing session events and rebuilding working context for each turn. It captures user messages, model outputs, and tool activity outside your runtime, so you can inspect histories, replay behaviour, and resume work without losing facts or open tasks. Use it alongside ADK or your own code via an HTTP API and adapters, and let automatic context compaction supply concise messages, summaries, and tasks to the next turn.
