# CLAUDE.md This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. ## Project Overview A static reference site comparing the Claude Code and ChatGPT/Codex extension ecosystems. The site covers Commands, MCP/Tools, Skills, Hooks, and Plugins for both platforms via interactive cheatsheets and concept reference pages. ## Architecture - Static HTML site — no build step, no framework, no bundler - All pages are self-contained HTML files with inline CSS and JS - Served via GitHub Pages from the `docs/` directory on `main` - Ecosystem cheatsheets use React 18 (CDN/UMD) with Babel standalone ## Key Files - `docs/index.html` — Landing page - `docs/claude-ecosystem-cheatsheet.html` — Claude ecosystem (React) - `docs/claude-concepts.html` — Claude concepts (plain HTML) - `docs/chatgpt-ecosystem-cheatsheet.html` — ChatGPT ecosystem (React) - `docs/chatgpt-concepts.html` — ChatGPT concepts (plain HTML) ## Development python -m http.server 8000 --directory docs ## Conventions - Each page is standalone — styles and scripts are inlined - Claude Code brand color: #d97757 - OpenAI brand color: #10a37f - 2-space indentation for HTML/CSS/JS - Lowercase hyphenated filenames with platform prefix

# Repository Guidelines ## Project Structure & Module Organization This repository is a static documentation site served from `docs/` via GitHub Pages. The main entry point is `docs/index.html`. Platform-specific reference pages live alongside it: - `docs/claude-ecosystem-cheatsheet.html` - `docs/claude-concepts.html` - `docs/chatgpt-ecosystem-cheatsheet.html` - `docs/chatgpt-concepts.html` There is no `src/` or shared asset pipeline. Each page is self-contained with inline HTML, CSS, and JavaScript. ## Build, Test, and Development Commands No install or build step is required. - `python -m http.server 8000 --directory docs` - Open `http://localhost:8000` to verify navigation and layout. - `git status` checks that only intended files changed. ## Coding Style & Naming Conventions Use standard HTML, CSS, and vanilla JavaScript with consistent 2-space indentation. Keep pages standalone: prefer inline styles and scripts over introducing shared build tooling. Name new pages with lowercase hyphenated filenames. Brand colors: - Claude: #d97757 - OpenAI: #10a37f ## Testing Guidelines No automated test suite. Validate changes manually in a browser. Check links, responsive layout, and interactive cheatsheet behavior. ## Commit & Pull Request Guidelines Short, imperative commit messages. PRs should include a brief summary, affected pages, and screenshots for UI changes.
