Simple explanation
Welcome to Day 5. Up until now Claude Code has been asking your permission before every single action. "Can I create this file?" "Can I run this command?" "Can I make this change?" Today that stops. What is Auto Mode? Auto Mode tells Claude Code to stop asking for permission and just build. You give it a task. It works through the entire thing start to finish. No interruptions. No yes/no prompts. It just does it. This is how experienced builders use Claude Code. They set a task running and move on to something else while it works. The rule you must follow first Always — always — create a GitHub branch before using Auto Mode. Auto Mode moves fast. It makes multiple changes without checking. That is the point. But without a branch — if something goes wrong — you have no safety net. Branch first. Auto Mode second. Every time. This is why Day 4 came before Day 5. Multi-Clauding — the real power move Once Auto Mode is running — you do not need to watch it. Open a second Claude Code window and start a completely different task there. Session 1 builds your contact page. Session 2 writes your about page. Both running. Both building. At the same time. You are no longer waiting for AI. AI is working while you work.
What to do
How to turn on Auto Mode Press Shift + Tab once inside a Claude Code session. You will see the mode indicator show Auto Mode is active. That is it. One keypress. Or type this at the start of your prompt: "Run this in auto mode: [your prompt here]" Today's practical task 1. Create a GitHub branch called "day-5-auto." 2. Open Claude Code. 3. Press Shift + Tab to turn on Auto Mode. 4. Ask Claude Code to build a complete about page with a heading, three short paragraphs, and a link back to the homepage. 5. While it builds — open a second Claude Code window. 6. Ask the second session to write three headline options for your homepage. 7. Watch both sessions run at the same time. Today's result: You have used Auto Mode and run two Claude Code sessions simultaneously.
Copy-paste prompt
Run in auto mode. Build a complete about page for this website. Include: a heading that says "About", three short paragraphs explaining what this site is and who it is for, and a link at the bottom that says "Back to home" pointing to the homepage. Match the existing design exactly. Do not change any other files.
Course note
Key takeaway
Auto Mode removes permission prompts so Claude Code builds without interruption. Always branch first. Then run Auto Mode. Then open a second session. That is how you build twice as fast.
