Claude
The Claude tag collects guides to Anthropic's assistant, Claude Code, skills and MCP for real work, written for beginners and developers alike. These are independent guides, not pages published by Anthropic. You will find plain explanations of AI agents, skills and MCP, setup walkthroughs for the coding tool on Windows and inside VS Code, a guide to writing a skill from a SKILL.md file, and steps for connecting an MCP server. Practical pieces cover research and source summaries, spreadsheets and résumés.
If you have never written code, read the explainer on what a skill is and the MCP guide for non-coders first. If you want to work on your own computer, continue with the piece on who Claude Code is for, then the setup guide for your operating system. Each guide cites official sources with the date they were checked, because features, install steps and prices can change.
