txcript: Switching coding agents mid-conversation

Austin-based startup txcript has introduced a new tool that allows users to seamlessly transfer coding conversations across different programming agents. The tool enables starting a conversation in one agent, such as Claude Code, and continuing it in another, like Codex, while preserving messages, reasoning, and tool history.

Developed using Rust, JavaScript, and a command-line interface (CLI), txcript provides prebuilt WebAssembly for Node and Bun. It supports various agents including Claude Code, Codex, OpenCode, Cursor, and more. Users can download binaries for macOS, Linux, or Windows from the Releases page or install from source with Rust 1.96 or newer.

To continue a conversation, users need to provide an agent-specific ID from the list or use an unambiguous prefix. The source session is kept alive while a new native session is created for the target agent. The original session is retained, allowing users to move project files separately.

txcript offers a simple JSON format called Simple, which represents conversation history, reasoning, tool calls, results, images, and metadata. This format is used for exporting conversations from agents without native adapters. However, not all agent-specific records and unsupported fields may be preserved during conversion.

The tool aims to enable users to move across AI chat platforms, facilitating the transfer of coding conversations between different agents. It supports creating documents with the run.json format, which can be used to store conversation history and other relevant data.
