What problem does it solve?
This Skill eliminates the risk of lost work context, out-of-sync project specifications, and incomplete session tracking when ending a development session, ensuring all progress is preserved and the next session can pick up seamlessly.
Core Features & Use Cases
- Spec Synchronization: Automatically updates project vision and active feature specs to match the actual code built during the session, marking completed "Done When" items and documenting newly discovered constraints.
- State & Backlog Management: Writes a detailed session summary, updates backlog and current task lists, and flags platform-relevant updates like new credentials or reusable utilities for human review.
- Use Case: A developer finishing a day of work building a new user authentication feature can use this Skill to automatically update the auth spec to match the implemented code, move completed backlog items to the done list, commit all changes, and write a summary of what was built for the next session.
Quick Start
Use the checkpoint skill to end your current development session, sync all project specs to match the work you completed, commit your changes, and write a session summary for the next session.
