+# Quick Task 002: Auto-rename Duplicate Playlists on Import Summary
+
+**One-liner:** CountPlaylistsByName query + uniquePlaylistName helper auto-appends (1), (2), etc. on M3U import when name collides
+
+## What Was Done
+
+### Task 1: Add CountPlaylistsByName SQL query and regenerate sqlc
+- Added `CountPlaylistsByName :one` query to `playlists.sql` — counts playlists with exact name match
+- Regenerated sqlc producing `CountPlaylistsByName(ctx, name) (int64, error)` in Go
+- **Commit:** `04b2088`
+
+### Task 2: Add uniquePlaylistName helper and wire into ImportPlaylist
+- Added `uniquePlaylistName(name string) string` method to playlist Service
+- Logic: if name exists, tries "Name (1)", "Name (2)", etc. until a free name is found
+- Wired single call `playlistName = s.uniquePlaylistName(playlistName)` in ImportPlaylist, between name derivation and CreatePlaylist call
+- CreatePlaylist and CreatePlaylistWithTracks remain unchanged — no auto-rename on manual creation
+- **Commit:** `8ba8bbe`
+
+## Verification Results
+
+| Check | Result |
+|-------|--------|
+| `go build ./backend/...` | ✅ Pass |
+| `go vet ./backend/...` | ✅ Pass |
+| CountPlaylistsByName in generated Go | ✅ Present |
+| uniquePlaylistName only in ImportPlaylist | ✅ 3 occurrences (comment, definition, one call site) |
+| CreatePlaylist unchanged | ✅ No uniquePlaylistName reference |
+| CreatePlaylistWithTracks unchanged | ✅ No uniquePlaylistName reference |
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
