How to Checkpoint (blog.conductor.build)

Conductor has introduced a new checkpointing feature that allows users to restore their development environment to a prior state with a single click, addressing limitations found in existing tools like Claude Code and Cursor. Unlike these competitors, which fail to reset certain changes made through external tools (like package managers and linters), Conductor aims for a comprehensive reset, ensuring that all modifications—tracked and untracked—are reverted. This is significant for the AI and machine learning community as it offers a more reliable and effective way to manage code states during AI model development, enhancing both productivity and the control over complex coding tasks. To implement this functionality, the Conductor team leveraged GPT-5, which provided a detailed specification and implementation strategy that fulfilled essential requirements like capturing and reverting complete states without altering user files. The solution integrates tightly into the agent's workflow, capturing three key aspects of the project state during each turn—current commit, staged changes, and untracked files—using hidden git references to maintain a clean git history. This innovative approach enables smoother experimentation and iteration in AI code development, allowing developers to focus on building without worrying about messy states.
