Build a Coding Assistant

Difficulty: intermediate

Explore and compare AI-powered coding tools and build your own

Step 1: Try existing coding agents

Recommended: Claude Code, Cursor, Aider, OpenAI Codex CLI, Continue

Each has different strengths — CLI vs IDE, autonomy vs control

Step 2: Understand how they work

Recommended: OpenHands (formerly OpenDevin), SWE-agent

Study research agents to understand coding agent architecture

Step 3: Add code execution safety

Recommended: E2B

Sandbox untrusted AI-generated code in isolated environments

Step 4: Connect to your tools

Recommended: MCP Servers (Official), MCP TypeScript SDK

Use MCP to give your agent access to GitHub, filesystems, databases
