How to Master Claude Code in 30 Minutes

TL;DR

To master Claude Code, set up its terminal experience, begin with codebase Q&A, and use specific prompts for larger engineering tasks such as writing functions, building features, and fixing bugs. It works across VS Code, Xcode, JetBrains IDEs, Vim, remote SSH, and T-Max without requiring code indexing. Read on for practical setup steps, security details, and ways to integrate Claude Code into daily development.

Transcript

[Applause] Hello. Hey everyone. Uh, I'm Boris. I'm a member of technical staff here at Anthropic and I created quad code and here to talk to you a little bit about some practical tips and tricks for using quad code. Um it's going to be very practical. I'm not going to go too much into the history or the theory or anything like this. Uh and yeah, be... Read More

Questions & Answers

Q: How do you get started with Claude Code?

Install Claude Code with NodeJS, then run terminal setup to enable Shift+Enter for new lines and use the theme command to select a preferred appearance. The speaker recommends starting with codebase Q&A by asking how specific code works or is used.

Q: What is Claude Code designed to do?

Claude Code is a fully agentic AI coding assistant designed for work beyond line-by-line completion. It can build features, write entire functions or files, and fix entire bugs.

Q: Which development environments work with Claude Code?

Claude Code works with VS Code, Xcode, JetBrains IDEs, Vim, and terminals. It can also run locally, over remote SSH, and through T-Max, allowing engineers to retain their existing workflows.

Q: How does Claude Code help engineers understand a codebase?

Engineers can ask how a particular piece of code is used or how to instantiate something. Claude Code explores the codebase, looks for usage examples, and can provide a deeper answer than a basic text search.

Q: How did Claude Code affect technical onboarding at Anthropic?

New technical hires at Anthropic install Claude Code on their first day and immediately use it to ask questions about the codebase. According to the speaker, technical onboarding decreased from about two or three weeks to about two or three days.

Q: Does Claude Code index or remotely store a codebase?

Claude Code does not create an index or remote database containing the code, and the code stays local. The transcript also states that Anthropic does not train generative models on that code.

Q: How can Claude Code be connected to GitHub?

Run the slash-install GitHub app command from the terminal to install the announced GitHub integration. After installation, users can mention Claude on a GitHub issue or pull request.

Q: How can users make prompting Claude Code more convenient?

Users can customize allowed tools so they are not repeatedly asked to approve the same actions. On macOS, they can also enable dictation under system accessibility settings and speak specific prompts to Claude Code instead of typing them.
