AgentFS with FUSE: SQLite-backed agent state as a POSIX filesystem

AgentFS introduces a novel abstraction for managing agent states by leveraging SQLite to form a unified filesystem for AI agents, compatible with TypeScript and Rust SDKs and soon Python. It allows developers to integrate AgentFS into various projects and offers a standardized SQLite schema with an SDK, enabling seamless integration with existing systems. By utilizing the Filesystem in Userspace (FUSE) interface, AgentFS can be mounted as a POSIX filesystem, granting agents compatibility with a wide range of Unix tools without the need for integration effort. This setup provides real-time observability, allowing developers to monitor agent activities and debug with familiar Unix commands like ls, cat, and tail. The FUSE support in AgentFS bridges the gap between the SQLite-backed filesystem's portability and queryability and the native filesystem-centric tools, making it ideal for coding agents and ensuring agent state remains auditable and portable.
