Skill Snapshot

中文文档

A Claude Code skill for creating snapshots of your skills with version control. Store backups in a private GitHub repository and restore any version when needed.

Features

• Snapshot Management: Save, restore, list, and diff skill versions
• Private GitHub Storage: Automatically creates and syncs to a private repository
• Smart Scanning: Automatically identifies which skills need backup
• Version Tags: Each snapshot is tagged (e.g., my-skill/v1, my-skill/v2)

Installation

Copy the skill-snapshot folder to your Claude Code skills directory:

cp -r skill-snapshot ~/.claude/skills/
