What problem does it solve? The underlying toolkit installer silently overwrites local modifications to installed skills with no warning, no merge, and no record of what was lost. This Skill wraps the update in a git-based safety net so every change the installer makes becomes a reviewable diff, and destroyed local tailorings are surfaced instead of discovered weeks later. ## Core Features & Use Cases - Pre-update safety checks: Verifies the directory is a git repository, the working tree is clean, and installed skills are tracked by git before allowing the update to run. - Change classification: After the update, classifies every changed file as a clean upstream update, a reverted local tailoring, or both, quoting removed content so nothing is silently lost. - Guided reconciliation: For each reverted tailoring, presents options to move it to a project-level slot, restore it in place, or let it go, with a recommendation. - Use Case: You run the toolkit update to get newer skill versions, and the Skill reports that two of your local edits were reverted, shows you the removed content, and helps you relocate those edits somewhere future updates cannot reach. ## Quick Start Update my installed toolkit skills and show me which of my local modifications were reverted by the update.
