Douban Collection Export

Export Douban user collections (books, movies, music, games) to CSV files. Douban has no official data export; the official API shut down in 2018.

What This Skill Can Do

• Full export of all book/movie/music/game collections via Frodo API
• RSS incremental sync for daily updates (last ~10 items)
• CSV output with UTF-8 BOM (Excel-compatible), cross-platform (macOS/Windows/Linux)
• No login, no cookies, no browser required
• Pre-flight user ID validation (fail fast on wrong ID)

What This Skill Cannot Do

• Cannot export reviews (长评), notes (读书笔记), or broadcasts (广播)
• Cannot filter by single category in one run (exports all 4 types together)
• Cannot access private profiles (returns 0 items silently)
