What is Wilsonic-MTS-ESP CLAUDE.md?

Project instructions for Wilsonic-MTS-ESP, covering how to build its standalone macOS app and audio plug-ins with Xcode. Audio plug-ins are components that run inside music software.

Building the standalone app and AU or VST3 plug-ins on macOS.

They give the coding agent the project's build commands and the correct targets to select.

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.

Model	Per session	Once invoked
Fable 5.1	$0.04063	$0.04063
Opus 5.5	$0.01625	$0.01625
Sonnet 5.5	$0.00813	$0.00813
Haiku 4.5	$0.00406	$0.00406

Security

Grade A, and why

Wilsonic-MTS-ESP CLAUDE.md 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 16d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Build Commands

JUCE version: 9.0.1. The .jucer files resolve modules through the Projucer's global module path (default ~/JUCE/modules); CI clones the 9.0.1 tag there. Regenerate Builds/ with Projucer --resave Wilsonic.jucer after pulling.

macOS (Primary Development Platform)

# Build standalone app and plugins using Xcode
open Builds/MacOSX/Wilsonic.xcodeproj
# Select target (Standalone, AU, VST3) and build

# Or build WilsonicController
open Builds/MacOSX-WilsonicController/WilsonicController.xcodeproj

Cross-Platform Build via Command Line

# Linux/CI build (using makefiles)
cd Builds/LinuxMakefile
make -j4 CONFIG=Release

# Run unit tests
make -C tests
./tests/test_wilsonicmath

Windows

# Open in Visual Studio 2022
Builds/VisualStudio2022/Wilsonic.sln

Parallel Development: Lanes and Worktrees

Work flows in three lanes — full contract in CONTRIBUTING.md:

Plugin (plugin/* branches): Source/, tests/, *.jucer. Gated by .github/workflows/plugin.yml (JUCE builds + C++ tests + research-seam CLI build).
Research (research/* branches): experiments/, plans/, prompts/, docs/. Gated by .github/workflows/research.yml (scorer freeze + Python suite). Research reads Source/ but NEVER edits it — harness-found plugin bugs become GitHub issues.
Chore (chore/* branches): docs, CI, scripts.

Non-negotiables for agents:

One lane per PR. Never mix Source/ and experiments/ changes.
Never edit experiments/triads/scorer.py or its pin — CI-enforced freeze; only Marcus changes the scorer.
Choke points are serialized: before touching WilsonicProcessor+Params.cpp, DesignsModel.*, *.jucer, or all_tunings.json, check gh pr list for another open PR touching them. Append-only ordering rules apply (see "Adding New Scale Designs" below).
Worktrees: scripts/worktree.sh new <lane> <topic> creates .claude/worktrees/<lane>-<topic> on branch <lane>/<topic>; list flags name/branch drift; done <name> is the only sanctioned teardown (stash-safe, refuses unmerged work). If a session auto-created a claude/* branch, rename to the lane prefix before opening the PR.
One running Wilsonic instance at a time when testing tuning output — MTS-ESP allows one master per machine, and a second worktree's build silently loses the master slot.
Licences are separate by artefact: all code is MIT, Ear Bench judgments (experiments/ear_bench/judgments/) are CC BY 4.0, and JUCE's licence applies only to distributing a built plugin binary. Research code must never depend on the real JUCE framework (the research seam builds against stub JuceHeader.h files). Details: CONTRIBUTING.md, "Licences: three separate questions".

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.
