Claude Code

Claude Code is a command-line tool that lets you delegate coding tasks to Claude directly from your terminal. It reads your codebase, makes changes, runs commands, and iterates, like pair programming with an AI that never gets tired.

The Claude Code workflow: describe what you want in plain English, let Claude plan and execute, review the changes, and iterate. The key shift is learning to describe OUTCOMES not IMPLEMENTATIONS.

Model Context Protocol (MCP) servers let Claude Code connect to external tools and data sources, GitHub, databases, APIs, file systems, and more. This turns Claude from a code editor into a full development assistant.

Patterns that work in practice: debugging with Claude, writing tests, refactoring legacy code, adding features to existing codebases, and managing complex multi-file changes.
