Tag: Claude-Code

If you’re using tools like Claude Code, GitHub Copilot Workspace, or similar, you’ve probably noticed there’s technical jargon that goes beyond simply “chatting with AI”. I’m talking about terms like rules, commands, skills, MCP, and hooks.

These concepts are the architecture that makes AI agents truly useful for software development. They’re not just fancy marketing words — each one serves a specific function in how the agent works.

Let’s break them down one by one in a clear way.

After my previous article about agent-centric programming, I’ve been researching more advanced techniques for using Claude Code really productively. As a programmer with 30 years of experience, I’ve seen many promising tools that ultimately didn’t deliver on their promises. But Claude Code, when used correctly, is becoming a real game-changer.

Beyond the basics: The difference between playing and working seriously

One thing is using Claude Code for experiments or personal projects, and another very different thing is integrating it into a professional workflow. For serious projects, you need a different approach:

A few days ago I came across a very interesting stream where someone showed their setup for agentic programming using Claude Code. After years developing “the old-fashioned way,” I have to admit that I’ve found this revealing.

What is Agentic Programming?

For those not familiar with the term, agentic programming is basically letting an AI agent (in this case Claude) write code for you. But I’m not talking about asking it to generate a snippet, but giving it full access to your system so it can read, write, execute, and debug code autonomously.

With the constant evolution of AI-powered development tools, Claude Code has introduced a revolutionary feature: Hooks. This feature allows developers to customize and automate specific behaviors in the Claude Code lifecycle, transforming suggestions into executable code that works deterministically.

Hooks represent a qualitative leap in the customization of AI development tools, allowing each team and developer to adapt Claude Code to their specific needs and project standards.

What are Claude Code Hooks?

Claude Code Hooks are user-defined shell commands that execute automatically at various specific points in the Claude Code lifecycle. Unlike prompting instructions, hooks guarantee that certain actions always occur, providing deterministic control over the tool’s behavior.
