name	vib3-dev
description	VIB3+ SDK development and expansion. Use when extending the engine, adding new geometries, developing shaders (GLSL/WGSL), creating MCP tools, writing tests, modifying the rendering pipeline, adding platform integrations, or working with the C++ WASM core. Use when this capability is needed.

VIB3+ SDK Development

Help extend, refactor, test, and build new features for the VIB3+ 4D visualization engine.

Gold Standard v3 & Codex Reference

When building creative features or examples, follow the Gold Standard v3 creative vocabulary:

• Gold Standard v3: examples/dogfood/GOLD_STANDARD.md — Motion vocabulary (14 motions), coordination grammar (7 patterns), composition framework, 3-mode parameter model, EMA smoothing, per-system personality
• Codex: examples/codex/ — Collection of annotated reference implementations showing different creative approaches
• Synesthesia (golden reference): examples/codex/synesthesia/ — Audio-reactive ambient with all 3 modes, all 6 rotation axes active, [WHY] annotations throughout

Key technical patterns from Gold Standard:

• EMA smoothing: alpha = 1 - Math.exp(-dt / tau) — never use setTimeout for visual parameter changes
• Hue convention: JS/API uses 0-360, shaders use 0-1. Convert at boundary: u_hue = hue / 360.0
• 4D rotation must have non-zero base velocity on XW/YW/ZW axes or the 4th dimension won't be visible
• Per-system personality: switching systems should change parameter ranges, not just shaders

Development Workflow

1. Read Before Writing

• CLAUDE.md — Architecture, shader system, C++ core, uniforms, projections
• Module-specific docs in DOCS/ (see References below)
• Existing source in the target module directory

2. Analyze Existing Patterns

• Constructor: new Module(options = {})
• Callbacks: (paramName, value) => void
• ES Modules throughout, JSDoc on public APIs
• No hidden globals beyond window.Vib3Core

3. Plan Changes

VIB3+ is highly interconnected — identify ALL affected files:

• Shader changes → GLSL + WGSL variants + inline shader sync
• New parameters → MCP tool schema + agent-config updates
• New systems → engine registration + keyboard shortcut + MCP enum

4. Implement → Test → Verify Shaders → Update Docs

Checklists

New Geometry

• Generator in src/geometry/generators/
• Register in src/geometry/GeometryFactory.js
• Metadata in src/geometry/GeometryLibrary.js
• GLSL in src/shaders/common/geometry24.glsl
• WGSL in src/shaders/common/geometry24.wgsl
• Update inline shaders in QuantumVisualizer.js, FacetedSystem.js, HolographicVisualizer.js
• C++ generator in cpp/geometry/ if WASM-accelerated
• Tests in tests/geometry/
• npm run verify:shaders

Warning: A 9th base geometry shifts all hypersphere (9-17) and hypertetra (18-26) indices — breaking change.

New Shader

• Both .glsl and .wgsl variants
• Standard uniforms (u_time, u_resolution, u_geometry, u_rot4d*, etc.)
• 6D rotation: rotateXY * rotateXZ * rotateYZ * rotateXW * rotateYW * rotateZW
• 4D→3D projection (perspective/stereographic/orthographic)
• Sync inline shaders with external files
• npm run verify:shaders

New MCP Tool

• Definition in src/agent/mcp/tools.js (name, description, inputSchema)
• Handler in src/agent/mcp/MCPServer.js handleToolCall()
• Update agent-config/claude-agent-context.md
• Update agent-config/openai-agent-context.md
• Tests in tests/agent/

New Visualization System

1. Create src/newsystem/ directory
2. Renderer following src/core/RendererContracts.js
3. Adapter in src/core/renderers/
4. Register in VIB3Engine.js switchSystem()
5. GLSL + WGSL shaders in src/shaders/newsystem/
6. Keyboard shortcut (next number key)
7. MCP switch_system enum in tools.js
8. Tests + CLAUDE.md update

New Platform Integration

• Follow src/integrations/frameworks/Vib3React.js pattern
• Lifecycle: init, update, destroy
• Map VIB3+ params to integration props
• GPU resource disposal (see DOCS/GPU_DISPOSAL_GUIDE.md)

Commands

npm test              # Unit tests (Vitest + happy-dom)
npm run test:e2e      # E2E browser tests (Playwright)
npm run verify:shaders # Shader sync (GLSL/WGSL inline vs external)
npm run lint          # ESLint
npm run bench         # Performance benchmarks
npm run dev           # Vite dev server
cd cpp && ./build.sh  # Build WASM core

---

Key Rules

1. 6D rotation order: Always XY → XZ → YZ → XW → YW → ZW
2. WASM optional: JS fallbacks in src/math/
3. WebGPU optional: Falls back to WebGL
4. 3 active systems: Quantum, Faceted, Holographic (Polychora is TBD)
5. Shader sync enforced: Pre-commit hook on .glsl/.wgsl changes
6. Column-major: C++ Mat4x4 = float m[16] column-major
7. Rotor normalization: Normalize after composition to prevent drift
