supercollider-synthdefs SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
supercollider-synthdefs from vecnode/vn-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Write, compile, load, debug and re-use SuperCollider SynthDefs with sc_synthdef - the unit of sound design in SuperCollider. Covers Out and ReplaceOut, argument naming, envelopes and doneAction, why a def must be loaded on a specific server before /s_new works, and how to read the compiler's error rather than guessing.
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
# SynthDefs ## Start from a working instrument **Before you write a def from nothing, look at the shelf.** This package ships sixteen instruments that are known to sound like what they say they are — a modal gong, an FM bell, a plucked string, three drum voices, a pad, a formant voice, a glass choir, an organ, a grain cloud, a feedback drone, a noise texture, a bitcrusher, a theremin: ``` sc_project action=examples # the catalogue, with what each one is sc_project action=examples file="3" # read 03-fm-bell and load it into the session sc_exec code="~fmBell.value(440)" # play it ``` Each file is a complete `.scd` that defines one `SynthDef` and one `~helper` to trigger it, and opens by naming the single DSP idea it is built on. Reading how `03-fm-bell.scd` falls its modulation index is faster and far more reliable than reasoning about FM from scratch — and every one of them is already at a level that does not clip, which is the mistake that turns a resonator bank into noise. Then vary it rather than replacing it: `sc_project action=read` the file, change a ratio or a decay, `action=write` it somewhere in the workspace, and `action=send` …

How to install
mdr add vecnode/vn-code/supercollider-synthdefs@sha256:f8189d9a1547025aThe line at the top of this page pins the label git:20261006.209a27d, 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.
