Regent Overview
Regent is a version control tool built for the era of AI-driven software development. It addresses the critical gap in managing the activity of AI coding agents by providing a system to track not just the files they change, but the entire conversation and reasoning behind each modification. Think of it as `git` for your AI agents, offering transparency and control when multiple agents are working on your codebase.
How to use Regent
Regent operates primarily through command-line interface (CLI) commands. You integrate it with your existing AI coding tools, and it begins capturing every agent action. Key commands include `rgt log` to view a detailed history of agent changes, `rgt blame` to trace any line of code back to its exact originating prompt and session, and `rgt sessions` to manage separate conversation branches for different agents or tasks, preventing conflicts during parallel work.
Core Features of Regent
- Complete Session Tracking: Captures the full conversation history and all file changes made by an AI agent, preserving the audit trail even if the agent itself compacts or resets.
- Precise Blame Functionality: Moves beyond simple file-level blame to trace every line of code to the specific prompt that generated it, spanning multiple sessions if necessary.
- Session Branching: Assigns each AI conversation its own branch, enabling multiple agents to work in parallel without collisions or merged histories.
- Undo and Replay: Provides the ability to safely rewind both code and conversation history to a previous state before an agent made a problematic change.
- Local Operation: Works locally, capturing agent activity in content-addressed storage for privacy and control.
Use Cases for Regent
Regent is indispensable for developers and teams heavily relying on AI coding assistants. Its primary use case is auditing and debugging AI-generated code changes—when an agent edits numerous files, Regent answers "what changed?", "which prompt caused it?", and "how can I undo this safely?". It is essential for environments with multiple AI agents working simultaneously (e.g., Agent A refactoring, Agent B writing tests) to maintain a clear, conflict-free history. It also serves as a critical tool for compliance and code review in professional settings.
Advantages of Regent
Regent offers unparalleled transparency into the "black box" of AI agent activity, which is its core advantage. Unlike starting fresh or using compact commands that destroy history, Regent preserves the full, immutable audit trail. It provides a familiar mental model for developers already versed in `git`, but tailored for the unique challenges of agentic development. By tracking the agent conversation rather than just files, it enables true root-cause analysis and safe recovery from agent errors.
