What problem does it solve? Saving code changes safely is hard when work mixes multiple concerns, targets already-merged history, or must preserve unrelated dirty files. This Skill provides a single entrypoint for all commit and local-history operations, routing automatically based on working-copy state while enforcing repository history policy. ## Core Features & Use Cases - Auto-routed saves: Detects working-copy state and routes to the correct procedure — default save, split, edit, parallel workspace, empty change, divergent change, or merged-target handling — without manual flag selection. - History rewriting with integrity proofs: Supports retrospective blame fixups, reordering, and editing prior changes, with automatic backup checkpoints and post-rewrite verification comparing Git tree and content hashes. - Manifest-scoped lifecycle saves: Saves an exact checksum-bound set of paths while proving byte-for-byte preservation of all unrelated dirty work. - Use Case: You have a mixed working copy containing a feature and an unrelated typo fix. Invoke the skill and it detects multiple concerns, proposes a split plan, creates self-contained conventional commits, and verifies each change compiles and passes tests in isolation. ## Quick Start Ask the assistant to save the current working-copy changes as clean conventional commits using the commit skill.
