What problem does it solve? Writing live-coded music in Strudel requires knowing its mini-notation, synth and effect APIs, and song-structure idioms, and a single syntax error silently leaves the pane playing the old pattern. This Skill provides the complete reference and a validation workflow so tracks parse and play correctly on every save. ## Core Features & Use Cases - Mini-notation and pattern authoring: Write sequences, subdivisions, Euclidean rhythms, polymeters, chords, and scale-degree melodies using Strudel's pattern language. - Offline-first sound design: Build drums and synths from oscillators, noise sources, and the synthesized sbd kick without needing internet-fetched samples. - Verdict validation: Run the verdict.py checker after every save to confirm the file parses with the same parser the REPL uses and to update the pane's status display. - Use Case: Ask for a 120 BPM minor-key groove; the Skill writes track.strudel with named stack voices (kick, bass, hats), runs the verdict, and the pane hot-swaps the pattern on the next cycle. ## Quick Start Ask the agent to write a four-on-the-floor groove with a sawtooth bassline in track.strudel and check it with the verdict.
