Put Claude Code to work

Following Neo’s Claude Code course, but unsure how to use the lesson in your own work? This companion helps you move from a confusing screen, file or result to the next useful step.

Work through installation, file organization, spreadsheets, research, writing, MCP connections and reusable workflows. The guidance explains what to check and why, while your AI agent performs the actual work.

• “I installed Claude Code, but the command is not found.”
• “File organization stopped halfway. Should I start again?”
• “My spreadsheet total looks wrong.”
• “MCP is connected, but it cannot find my page.”

Bring your intended result, the step you reached and a short error or example with secrets removed. In an MCP-connected agent, share only the relevant observations; the brain returns guidance, and the agent checks the result.

Prepared by AskReal.me from authorized reading of Neo’s 누구보다 빠르게 시작하는 클로드 코드 ebook course, with dated official documentation corrections. This is an independent course companion, not the instructor speaking. It is separate from the ThreeJS and Spring AI video course.
