Save exact Spotify track IDs to Liked Songs and re-read their state for verification.

Return one page of the current user's Spotify playlists.

Return metadata for an exact Spotify playlist ID.

Update metadata for an exact playlist ID and re-read each requested field once for verification.

Add exact Spotify track IDs or track/episode URIs. A returned snapshot proves acceptance; a missing snapshot is reported as ambiguous and must not be retried blindly.

Compare Spotify and ReccoBeats readings for exact track IDs. Provider failures, missing providers, missing fields, and material conflicts remain explicit.

Audit audio-analysis coverage and conflicts for exact Spotify track IDs without changing Spotify or treating heuristic measurements as musical quality scores.

Fetch current audio evidence and store a position-safe DJ analysis.

Use anchor to retain incomplete tracks in place or error to reject incomplete analysis. Explicit legacy features override provider values. Audio is fetched for each call; this tool does not maintain a feature cache.

Create an immutable deterministic DJ order without changing Spotify.

Preview or apply a plan with snapshot checks, receipts, and fresh verification.

Preview or restore the exact pre-plan order recorded in a mutation receipt.

Audit every position in a Spotify playlist for audio-feature coverage, exact and likely duplicate recordings, tempo ambiguity, provider conflicts, and heuristic opening, peak, and reset candidates without changing Spotify.

Preview or apply the compatibility BPM and energy ordering workflow. Dry-run is the default; applying uses snapshot checks, durable receipts, and fresh verification.
