Show HN: Stepbook – run long agent tasks as short steps with saved state (github.com)

Stepbook, an innovative tool designed for AI agents, allows users to execute long tasks as a series of manageable short steps, each with its own saved state. This system enables agents to pause, send notes, and resume tasks or even transfer them to another agent. Stepbook works seamlessly with popular AI models like Claude Code, Codex, and OpenCode, making it versatile for complex tasks that require iterative checking, such as passing commands or migrating services. The ability to handle long workflows through fresh agent sessions significantly reduces the token usage compared to traditional single-session methods. The significance of Stepbook for the AI/ML community lies in its approach to breaking down extensive tasks into smaller, verifiable components, which enhances efficiency and resource management in AI applications. By adopting a fresh agent session for each step, Stepbook minimizes the accumulated context burden, allowing for simpler state management while ensuring that each action is well-documented and validated against predefined schemas. This method fosters not only clearer progress tracking but also easier maintenance and collaboration, as any agent capable of accessing the project can take over a task mid-way, thereby streamlining collaborative AI efforts in software development and data processing.
