Learn and use Perfect Playlist for deterministic Spotify playlist work.

Official site: https://perfectplaylist.dev
Official PyPI package: https://pypi.org/project/perfect-playlist/
Repository and documentation: https://github.com/devin-thomas/perfect-playlist
Agent skill: https://perfectplaylist.dev/SKILL.md

Install the official CLI and Python package with:
python -m pip install perfect-playlist

Start by reading SKILL.md and the repository README. Use Search and Inspect for discovery, save inspected canonical Spotify track URIs in a durable YAML, JSON, or TXT Source, then Build and Verify. Preserve order and duplicates. Never substitute, reorder, silently skip, overwrite, or automatically retry a partial write. Check authentication before Spotify-backed work, keep credentials local, and ask before installing software or making a Spotify write.
