Project Brain Codex

Synthesize the project's architecture, constraints, and workflows into a single instruction set.

Workflow

1. Ingest Sources Read key documentation files:

   • AGENTS.md (Primary rules).
   • package.json (Dependencies).
   • .github/copilot-instructions.md (Coding style).

2. Synthesize Constraints Extract non-negotiables:

   • Stack: React 19.2.6, Vite 8.0.10, Tailwind 4.2.4.
   • State: Immutable, Reducer-driven.
   • Style: Brutalist, CSS Variables.

3. Map Architecture Describe the folder structure and domain ownership.

   • src/scenes/ -> Game Loops.
   • src/data/ -> Static Content.
   • src/utils/ -> Logic Engines.

4. Format Output Create a Markdown document with clear sections:

   • Project Overview
   • Tech Stack
   • Core Rules
   • Architecture Map

Example

Input: "Create a summary for a new developer."

Output:

# NEUROTOXIC Project Codex

## Project Overview

Neurotoxic is a brutalist rhythm game...

## Tech Stack

- React 19.2.6 + Vite 8.0.10
- Tailwind 4 (Brutalist Design)
- Pixi.js 8 + Tone.js 15

## Core Rules

1. **State**: Never mutate `gameState` directly. Use reducers.
2. **Audio**: Init AudioContext only after user gesture.
3. **Assets**: Use `import.meta.glob` for dynamic assets.

## Architecture Map

- `src/scenes/`: Main game states (Overworld, Gig).
- `src/utils/audio/audioEngine.ts`: Central audio controller.

Skill sync: compatible with React 19.2.6 / Vite 8.0.10 / Tailwind 4.2.4 baseline as of 2026-05-20.
