juce-visage

juce-visage is a skill for Claude Code from danielraffel/generous-corp-marketplace. It costs 172 tokens per session (3,581 once invoked), scanned A, original, MIT.

A guide for embedding the Visage GPU-accelerated user interface framework in JUCE audio plugins and apps on macOS, iOS, and iPadOS. JUCE is a framework for building audio software, while a DAW is an app used to record and produce music.

In plain words
What is it for?
Use it to build or debug JUCE plugins and apps using Visage, including AU and VST3 plugins, standalone macOS apps, and iOS/iPadOS interfaces.
Why use it?
It addresses platform-specific problems with rendering, mouse and touch input, keyboard focus, popups, memory cleanup, and plugin validation. It helps the Visage interface behave correctly inside host applications.

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

juce-visage 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 11d 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.

JUCE + Visage Integration Guide

This skill covers how to build a JUCE audio plugin (AU/VST3/Standalone) or iOS/iPadOS app that uses Visage for its UI.

Scope: macOS and iOS/iPadOS (Metal rendering, NSView/UIView embedding, event bridging). On macOS, the bridge forwards mouse events from JUCE to Visage. On iOS, Visage's VisageMetalView handles touch events natively — the bridge skips mouse forwarding entirely.

Tested with: Visage (VitalAudio fork, included directly in repo), JUCE 7/8, Logic Pro, Ableton Live, Reaper.

When to Use This Skill

Use when:

  • Starting a new JUCE plugin project that will use Visage for its UI
  • Adding Visage UI to an existing JUCE plugin
  • Building a JUCE iOS/iPadOS app with Visage GPU-accelerated UI
  • Debugging rendering, keyboard, mouse, touch, or focus issues in a JUCE+Visage plugin/app
  • Building modals, overlays, dropdowns, or secondary windows with Visage inside JUCE
  • Porting Visage standalone patterns into a DAW plugin context
  • Troubleshooting AU/VST3 validation timeouts or scanner failures
  • Making a standalone JUCE+Visage app look native on macOS
  • Adapting macOS Visage UI for iOS touch interaction and safe areas

Do NOT use when:

  • Building a pure JUCE UI (no Visage)
  • Building a standalone Visage app without JUCE
  • Working on audio processing, DSP, or MIDI logic unrelated to the UI layer

Per-Project Notes

This skill provides generic patterns. Each project should maintain a docs/juce-visage-notes.md file with project-specific details — bridge layer file paths, applied patches, destruction sequences, popup/modal/dropdown inventories, JUCE exceptions, technical debt, and learnings.

Claude's behavior with per-project notes:

  • On Visage tasks: Look for docs/juce-visage-notes.md in the project root. Read it alongside this skill.
  • If missing: Offer to create it from the template in references/troubleshooting.md (see "Maintaining Per-Project Notes").
  • After solving issues: Update the per-project file with new learnings, new popup/modal instances, or newly discovered patterns.

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.
