What problem does it solve? Closing out a work session often means losing context about what shipped, why decisions were made, and what to pick up next. This Skill captures that state in a standardized checkpoint file committed to the repo, so the next session starts with full context. ## Core Features & Use Cases - Template-based checkpoint generation: Writes memory/checkpoint-YYYY-MM-DD-<topic>.md with fixed sections (What shipped / Design decisions / Deferred / Board state / Next pickup), matching the style of prior checkpoints. - Live board state capture: Runs gh issue list to embed currently-open GitHub issues in the checkpoint. - Safe git workflow: Commits on the current feature branch with a heredoc message, refuses to run on main, and defers to pre-merge-housekeeping when bundling before a merge. - Use Case: After finishing a shooting-engagements feature in the turnipsim repo, ask for a checkpoint to document the session and commit it before opening a PR. ## Quick Start Ask the assistant to checkpoint this session with the topic slug for the feature you just finished.
