The Missing Manual for Coding Agents: Claude Code, Copilot, Codex, Cursor, Antigravity - Skills, MCP, Plugins, Subagents
# AI Vibe Engineer A comprehensive repository showcasing **multiple AI-powered Kanban board implementations** and learning projects built as part of the Complete AI Coder Course. This repository demonstrates how different AI coding assistants (Codex, Cursor, Cursor, and Antigravity) can be used to build the same project with varying approaches and results. ## Project Overview This repository contains 5 complementary projects: ### 1. **Antigravity Kanban** A modern Kanban board implementation with advanced features. - **Tech Stack**: Next.js, TypeScript, React - **Features**: - Drag-and-drop card management - Renameable columns (To Do, In Progress, In Review, Done, Archived) - Add/delete/move cards between columns - Full test coverage with Vitest - E2E testing with Playwright - ESLint configuration for code quality **Quick Start**: ```bash cd antigravity_kanban/frontend npm install npm run dev ``` Visit: http://localhost:3000 **Testing**: ```bash npm run lint npm run test npm run test:e2e ``` --- ### 2. **Codex Kanban** Kanban implementation built with OpenAI's Codex AI assistant. - **Tech Stack**: Next.js, TypeScript, React - **AI Assistant**: OpenAI Codex - **Highlights**: - Community contributions and agent configurations - Comprehensive AGENTS.md for AI-assisted development - Production-ready implementation **Quick Start**: ```bash cd codex_kanban/frontend npm install npm run dev ``` **Documentation**: - [AGENTS.md](./codex_kanban/AGENTS.md) - AI assistant configuration - [Community Contributions](./codex_kanban/community_contributions/) --- ### 3. **Cursor Kanban** Full-featured Kanban board built with GitHub Copilot. - **Tech Stack**: Next.js, React, Jest, Playwright - **AI Assistant**: GitHub Copilot - **Features**: - Complete implementation with all MVP features - Jest unit tests - Playwright E2E tests - Context management with React Context - Comprehensive documentation **Quick Start**: ```bash cd copilot_kanba
Agent that generates comprehensive documentation, API references, architecture diagrams, and developer onboarding guides from existing code.
Agent configuration for systematic bug investigation that traces issues from error logs through the codebase to root cause with suggested fixes.
Agent for integrating third-party APIs including SDK setup, type generation, error handling, retry logic, and rate limit management.
Cursor's built-in autonomous coding agent that can make multi-file edits, run terminal commands, search the codebase, and iteratively build features with minimal human intervention.
Cloud-based autonomous coding agent that runs in the background on remote sandboxed environments, handling complex multi-step tasks while you continue working.
Cursor's multi-file editing agent within Composer mode that can create, edit, and delete files across your entire project in a single conversation.
