+- [x] Confirm current Cline skills path is `.cline/skills/{skill-name}/SKILL.md` with YAML frontmatter (name + description)
+- [x] Implement installer migration to native skills output
+- [x] Add legacy cleanup for `.clinerules/workflows`
+- [x] Test fresh install — 43 skills installed to `.cline/skills/`
+- [x] Test reinstall/upgrade from legacy workflow output
+- [x] Confirm no ancestor conflict protection is needed because Cline only scans workspace-local `.cline/skills/` and global `~/.cline/skills/`, with no ancestor directory inheritance
+- [x] Implement/extend automated tests — 9 assertions in test suite 18
