Claude Code

Claude Code is Anthropic's AI coding agent that runs directly in your terminal. Unlike copilot-style tools that only suggest completions, Claude Code operates as a fully autonomous coding agent — it reads files, writes code, executes shell commands, runs tests, searches your codebase, and completes multi-step engineering tasks from a single natural language prompt. It understands your entire project structure, not just the file you have open. For developers building production AI systems, Claude Code eliminates the constant context-switching between editor, terminal, and AI chat interface that fragments deep work and slows shipping. The result is a fundamentally different development workflow: instead of asking an AI for suggestions and then implementing them yourself, you describe what you want and Claude Code autonomously implements it end-to-end.

Claude 3.5 Sonnet — the model powering Claude Code — achieved 49% on SWE-bench Verified (Anthropic, 2024), the most rigorous AI coding benchmark, placing it at the top of all publicly available models at release. In production use, teams report Claude Code reducing routine coding tasks from hours to minutes through autonomous multi-file refactors, test generation, and debugging.

The most powerful Claude Code setups use CLAUDE.md files to encode project context, hooks to automate post-edit formatting and linting, and multi-agent workflows to parallelize independent tasks. The difference between amateur and professional Claude Code usage often comes down to these configuration choices.

At The AI How, we cover Claude Code from initial setup through advanced production patterns. Whether you want to understand session limit management, build custom agent workflows, or squeeze maximum performance out of your AI coding setup, we have in-depth tutorials built for AI builders who use Claude Code daily.
