Feature & Specification Comparison
Tools & Capabilities Breakdown
Crompton Network Tools (26)
crompton_hello
Discover the album. Returns greeting, track count, and entry points for the Stage API. Call this first.
crompton_album_manifest
Get the ordered track list for a full-album listen: 13 tracks with stream URLs, durations, and the compositional silences between each pair. Use this when you want to listen to the album end-to-end. Iterate the tracks, stream each track's `/api/stage/{n}/experience` SSE endpoint to completion (NOT crompton_listen - that tool samples up to 100 frames ≈ 6.7s only), and sit through the intertrackGap before opening the next. See crompton_cookbook section=recipe-4 for the listening pattern.
crompton_track
Get metadata for a specific track: title, theme, lead performers, audio stats, available endpoints.
crompton_brief
Get an ~800-token single-call summary of a track. Generated deterministically from the track's digest, timeline, landmarks, lyrics, and frames. Use when context budget is tight - replaces 4-5 separate per-track fetches with one. Returned as Markdown in `broadcast.brief`.
