+# BrainWaves — Claude Code Rules
+
+## Project Overview
+BrainWaves is an Electron + React desktop application for running EEG experiments. It uses electron-vite for bundling, Redux + redux-observable for state management, and Pyodide (WASM) for in-app Python data analysis. Its primary usecase is making EEG data collection and analysis easy for students
+
+## Background
+This app is fairly complex in that it involves communicating with external EEG devices over bluetooth, with high precision and speed goals, and doing scientific computing within a frontier python-in-the-browser environment.
+Reliability and visibility of these different sources of complexity is thus most important for developers.
+The UI of the app should have a lighthearted and fun feel, since its target audience is students.
+Redux Observables are hard to learn, but powerful. They help encapsulate complex temporally sensitive logic into functions. They should be maintained as an approach going forward, at least until a refactor is made.
+A priority for this codebase is extensibility modularity and hackability. There are many features on the horizon such as swapping out hard-coded analysis for block-based programming, or even an embedd notebook environment. As such, effort should be taken not to hard-code things or cut corners by leaking abstractions.
+
+## Stack
+- **Runtime**: Electron (main) + React 18 (renderer)
+- **Bundler**: electron-vite / Vite
+- **State**: Redux Toolkit + redux-observable (RxJS epics)
+- **Language**: TypeScript (strict)
+- **Styling**: Semantic UI React + SCSS
+- **Testing**: Jest
+- **Linting**: ESLint + Prettier (single quotes, ES5 trailing commas)
+
+## Key Directories
+- `src/main/` — Electron main process
+- `src/renderer/` — React renderer process
+- `src/preload/` — Electron preload scripts
+- `src/renderer/experiments/` — Lab.js experiment files
+- `src/renderer/utils/pyodide/` — Pyodide WASM Python runtime
+
+## Dev Workflow
+```bash
+npm run dev          # Start dev server (patches deps first)
+npm run build        # Build all processes
+npm test             # Run Jest tests
+npm run typecheck    # TypeScript check (no emit)
+npm run lint         # ESLint
+npm run lint-fix     # ESLint + Prettier auto-fix
+npm run package      # Build + package for current platform
+```
+
+## Conventions
+- Use TypeScript; avoid `any` unless strictly necessary
+- Redux state changes go through RTK slices or typed actions via `typesafe-actions`
+- Side effects belong in RxJS epics (`redux-observable`)
+- Do not commit secrets or device credentials
+- Keep Electron main/renderer separation strict — use preload IPC bridges
+
+## Out of Scope
+- Do not modify `src/renderer/utils/pyodide/src/` directly; it is managed by `InstallPyodide.js`
+- Do not alter `electron-builder` publish config without confirming release intent
+
+## LLM Context
+Shared context for agents and developers lives in `.llms/`:
+- `.llms/CLAUDE.md` — this file; stable conventions and architecture
+- `.llms/learnings.md` — accumulated codebase insights from agents and developers
+
+When you discover something non-obvious about the codebase (a gotcha, a hidden dependency, a tricky pattern), add it to `.llms/learnings.md` so future agents and developers benefit.
