Generate a looped or cinematic music track — loops authored at >=30s with a marked loop point, cinematic tracks at >=60s linear.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# /music-track — Generate a Loop or Cinematic Music Track ## Overview ElevenLabs Music renders a track from a prompt. Summer clamps the requested length to **3–600 seconds** before sending it, so anything outside that range is silently pulled to the nearest bound. Quality depends on prompt specificity: tempo (BPM), key, instrumentation, mood, structural cue. "Epic orchestral" returns generic stock music. "85 BPM, D minor, solo cello and detuned upright piano, sparse, melancholic, no drums, 4/4" returns a usable score for a melancholic exploration scene. This skill produces one track aligned with the audio bible's music style and dynamic music plan, then wires it as an `AudioStreamPlayer` on the `Music` bus with a marked loop point if it's a loop, or as a linear cinematic stream if it's a one-shot. ## When to use - Looped track for a level, biome, menu, or game state (calm / tension / combat). - Cinematic linear track for an intro, ending, boss reveal, or cutscene. - Replacing a placeholder loop with on-bible music. ## When NOT to use - Short stings / event punctuation (<5s) → use `sound-effect` with class `Stinger`. …

How to install
mdr add summerengine/summer/music-track@sha256:eeaa6fa689d388a3The line at the top of this page pins the label git:20261010.4ade947, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
