yup-review

yup-review is a skill for Claude Code, Codex from kunitoki/sonic-skills. It costs 117 tokens per session (1,461 once invoked), scanned A, original, Unlicense.

A code review guide for YUP audio plugins, which are software instruments or effects that run inside music applications.

In plain words
What is it for?
Use it to review plugin lifecycle code, audio processing, parameter handling, input and output buses, editor behavior, state recall, and MIDI handling.
Why use it?
It helps catch mistakes specific to YUP's audio processing, controls, editor, saved state, and plugin formats, in addition to general audio-safety checks.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

yup-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

YUP Audio Plugin Review

YUP looks JUCE-like in places, but its plugin API has its own parameter handles, bus layout, editor contract, and wrapper behavior. Review those directly instead of applying APVTS rules.

Step 0 - Run universal checks first

Invoke audio-dsp-review and audio-numerics-review before this skill. This skill adds YUP-specific checks on top; it does not replace realtime-safety or numerics reviews.

Step 1 - Identify plugin structure

Locate the core classes and boundaries:

  • yup::AudioProcessor - audio thread owns processBlock; wrapper/host code calls lifecycle, state, and preset methods
  • yup::AudioProcessorEditor - UI/message thread only; never call from audio thread
  • yup::AudioParameter - atomic scalar value plus listeners for host/UI notification
  • yup::AudioParameterHandle - audio-thread smoothing/read path; initialise in prepareToPlay
  • yup::AudioBusLayout - immutable I/O contract exposed to plugin wrappers
  • extern "C" yup::AudioProcessor* createPluginProcessor() - plugin entry point used by wrappers

Step 2 - Scan for YUP violations

Violation Where to look Risk
AudioParameterHandle default-constructed and used before prepareToPlay Members and processBlock Null parameter assertion/crash; wrong smoothing state
Missing handle.updateNextAudioBlock() processBlock Automation and smoothing lag or never update
Recreating AudioParameterHandle in processBlock Audio callback Reinitialises smoothing and may add avoidable work/glitches
setValueNotifyingHost(), beginChangeGesture(), or endChangeGesture() from audio code processBlock, MIDI handlers, DSP helpers Listener/host notification path is not a realtime data path
Allocating voices, buffers, MemoryBlock, String, std::vector, or smart-pointer objects in processBlock MIDI note-on, scratch buffers, metering Heap traffic causes xruns
YUP_DBG, Logger::writeToLog, File, URL, JSON/XML, or string formatting in audio code Debug and error paths Logging/I/O/allocation on audio thread
Hard-coded channel pointers without layout checks getWritePointer(0/1) and bus setup Mono, sidechain, or unusual host layout crashes/corrupts audio
Mutating MidiBuffer while iterating it MIDI loops Iterator invalidation or unbounded allocation
prepareToPlay not resetting all DSP and note state Lifecycle methods Host reactivation leaves stale filter history, held notes, or ramps
flush() missing for synths/effects with tails or voices CLAP reset handling Host reset leaves hanging notes or stale delay/reverb tails
State load/save left unimplemented loadStateFromMemory, saveStateIntoMemory DAW session recall and presets fail
Long work under getProcessLock() or state swaps with no handoff UI/state/background code Processing may skip under CLAP try-lock or race under other wrappers
Editor stores raw processor-owned UI pointers or processor stores editor pointer Editor/processor members Dangling pointer when host closes editor

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
