Build Steps

Understand the Problem

Claude's training data has a cutoff date, so it may not know about the latest framework versions, APIs, or breaking changes. Context7 solves this by fetching live documentation.

Install Context7 MCP

Add Context7 to your Claude Code MCP configuration. The MCP provides tools that Claude can call to fetch current documentation for frameworks you're working with.

Code

// Add to your MCP config
// Context7 fetches up-to-date docs on demand
// Claude calls it when working with unfamiliar frameworks

Use in Your Workflow

When you ask Claude to work with a framework, it can fetch the latest docs before generating code. This means correct, up-to-date implementations rather than guessing from old training data.

Adopt a Monorepo Structure

CJ recommends monorepos for AI-assisted development. When everything is in one repo, Claude can read the backend while fixing the frontend without context switching across repositories.
