Claude is one of the best AI models for code generation. Sonnet 4.6 is the first Sonnet model to beat the previous Opus in coding benchmarks. But good code generation depends on how you ask. This article covers 10 best practices that will get you better code from Claude every time. This is Article 19 in the Claude AI — From Zero to Power User series. You should know Prompt Engineering Basics and Tool Use before this article. ...

A prompt that works on three examples might fail on the fourth. Prompt engineering without testing is guessing. In this article, you will learn how to test prompts systematically, measure quality, and iterate until you get reliable results. This is Article 18 in the Claude AI — From Zero to Power User series. You should know Prompt Engineering Basics before this article. By the end, you will have an eval harness that tests your prompts automatically and a process for improving them. ...

Claude knows a lot, but it does not know your company documents, your codebase, or your private data. RAG (Retrieval-Augmented Generation) fixes this. You give Claude relevant context from your own documents, and it answers questions based on that context. This is Article 17 in the Claude AI — From Zero to Power User series. You should know the Messages API before this article. By the end, you will build a working RAG pipeline that answers questions from your own documents. ...

Claude can see your screen and control your computer. It takes screenshots, analyzes what is on screen, then clicks buttons, types text, and navigates applications — just like a human would. This is Article 16 in the Claude AI — From Zero to Power User series. You should know Tool Use before this article. By the end, you will build a working desktop automation that fills out a web form automatically. ...

One agent is powerful. Multiple agents working together are transformative. A code review agent checks for bugs while a test agent writes tests and a documentation agent updates the docs — all in parallel. Multi-agent systems let you break complex tasks into specialized roles. This is Article 15 in the Claude AI — From Zero to Power User series. You should have completed Article 14: Building AI Agents before this article. ...

An AI agent is not a chatbot. A chatbot answers questions. An agent takes actions. It reads files, writes code, runs commands, queries databases, and makes decisions — autonomously. The Claude Agent SDK gives you the same tools that power Claude Code, but programmable. This is Article 14 in the Claude AI — From Zero to Power User series. You should have completed Article 8: Tool Use and Article 13: MCP before this article. ...

Tool use lets Claude call functions you define in your API request. MCP goes further — it lets Claude connect to external servers that provide tools, data, and prompts. MCP is the bridge between Claude and the rest of your infrastructure. This is Article 13 in the Claude AI — From Zero to Power User series. You should have completed Article 8: Tool Use before this article. By the end of this article, you will understand MCP architecture, use pre-built MCP servers, and build your own MCP server in both Python and TypeScript. ...

Here are the 5 biggest AI stories from the week of April 13–19, 2026. 1. Anthropic: Claude Opus 4.7 Anthropic released Claude Opus 4.7 this week. The headline numbers: 3× more production bugs fixed on SWE-bench compared to the previous model 98.5% on vision tasks — near-perfect image understanding New /ultrareview command in Claude Code for deeper code analysis The catch: Opus 4.7 uses a new tokenizer that adds up to 35% more tokens on code-heavy tasks, which increases cost even though the per-token price stayed the same. If you work with a lot of code, run the math on your current usage before upgrading. ...

Google announced a new tool for Android developers: Android CLI. It works with any AI agent — Claude Code, Gemini CLI, Codex, or others. It makes AI-assisted Android development 3x faster and cuts LLM token usage by 70%. In this article I’ll explain what Android CLI is, what commands it has, and how to get started. What Is Android CLI? Android CLI is a command-line tool built for AI agents. ...

Some problems need thinking. A complex debugging task, a math proof, or a multi-step architecture decision — these benefit from Claude reasoning through the problem before answering. Extended thinking makes this explicit and controllable. This is Article 12 in the Claude AI — From Zero to Power User series. You should have completed Article 7: Messages API before this article. By the end of this article, you will know how to enable extended thinking, set thinking budgets, and decide when to use it. ...
