What problem does it solve? Users who installed clauDNA before it became a marketplace plugin have stale skill, agent, and hook copies in ~/.claude/ that shadow the plugin-installed versions, causing outdated behavior and confusion. ## Core Features & Use Cases - Discovery-Based Detection: Enumerates the plugin's shipped components and only flags matching-name files in the legacy overlay, leaving user-created files untouched. - Customization Safety Check: Diffs each legacy file against the plugin version and requires per-file confirmation for anything that differs, so user modifications are never silently deleted. - Backup Before Removal: Copies the full removal manifest to a timestamped backup under ~/.local/share/clauDNA/backups/ before deleting anything. - Use Case: After installing the claudna plugin via the marketplace, run this skill to clean up the old install.sh overlay, fix a stale statusLine path in settings.json, and verify /claudna: skills resolve to the plugin copies. ## Quick Start Ask the assistant to clean up the legacy clauDNA install from ~/.claude/ now that the marketplace plugin is installed.
