Anthropic

Introduction The landscape of software engineering is undergoing a seismic shift. For decades, the relationship between a developer and their computer was mediated by manual input: typing commands, clicking buttons, and switching between windows. With the release of Claude Code and the Computer Use capability, Anthropic has introduced a paradigm shift where the AI is no longer just a chatbot, but an active participant in the operating system. Claude Code is a command-line interface (CLI) tool that allows Claude to interact directly with your local development environment. When paired with the broader “Computer Use” API—which enables Claude to perceive a screen, move a cursor, and execute keyboard events—we are witnessing the birth of the “AI Agent” era. ...

Introduction Claude Code introduces a powerful feature called Skills—a way to teach Claude repeatable, specialized capabilities that persist across sessions. Think of Skills as plugins for behavior: structured instruction sets that define exactly what Claude should do, when to do it, and which tools it can use. Unlike one-off prompts that you type into chat, Skills are persistent, discoverable, and automatically selected by Claude based on context. They transform Claude from a general-purpose assistant into a specialized agent that can reliably perform complex, domain-specific tasks. ...
