claude-snapshot exports and imports portable snapshots of your entire Claude Code setup across machines. It captures settings.json, plugins, marketplace registrations, hooks, and global CLAUDE.md files into a single .tar.gz file with a manifest index. Absolute paths are normalized to $HOME for cross-machine portability. On apply, it backs up conflicting files as .bak and installs missing plugins automatically. Supports slim (config only, ~6KB) and full (with plugin caches for offline restore) export modes.
