· 2 sourcesre_gent, an open-source version control system for AI coding agents, has been released. Hacker News reported that it automatically tracks every tool call an agent makes and captures which prompt wrote each line of code, enabling rewinding when things break. Product Hunt added that unlike traditional Git, re_gent traces the agent's step-by-step actions, allowing users to blame code changes back to specific prompts and preserve history even when sessions are compacted. The tool addresses the fundamental problem that AI agents currently lack their own version control systems.
Hot, fresh, and worth queueing round the block for.
Summary
re_gent is an open-source version control system designed specifically for AI coding agents. It automatically tracks every tool call an agent makes, captures which prompt wrote each line of code, and enables rewinding when things break. The tool provides auditability for AI agent activity without requiring manual commits, offering features like blame tracking (which prompt produced which code), concurrent session management, and full context for any change. It addresses the fundamental problem that AI agents currently lack their own version control systems.
