Move AI chats across harnesses: Claude Code, Codex, OpenCode, Cursor, and more (github.com)

A new library called txcript has been released, enabling users to seamlessly transition coding conversations between various AI agents such as Claude Code, Codex, and others, by converting and preserving the context of agent sessions. This functionality allows developers to start a project in one coding agent and continue it in another without losing historical context, including messages, reasoning, and tool usage. The library supports multiple platforms, with a Rust API, a JavaScript package, and a command-line interface (CLI), making it accessible to a wider range of developers. The significance of txcript lies in its ability to enhance collaboration and efficiency in AI-assisted coding. By allowing conversation transfers across agents, developers can leverage the strengths of different AI tools while maintaining continuity in their project work. Key technical features include the ability to search, view, and edit session histories and the conversion of sessions into standardized formats for interoperability among different AI systems. This innovation broadens the possibilities for integrating diverse AI functionalities, potentially leading to more sophisticated and adaptable coding environments.
