Anthropic released a 30-minute masterclass that walks through how they actually use Claude Code internally.

The speaker is Boris Cherny, the engineer who built Claude Code at Anthropic. He uses it daily on the codebase that produces it. Around 80% of Anthropic’s technical staff do the same.

Boris doesn’t pitch the product. He walks through the actual habits behind his daily use. I pulled out the 8 lessons that have real teeth.

And since we’re talking about Anthropic: I’m including their original pitch deck as a bonus. It’s one of the cleanest examples of positioning as strategy in modern tech: how to win trust before you win distribution, turn “safety” into a product moat, and raise institutional capital for a research-heavy business. It’s at the end of this newsletter.

Inside you will find:

  1. Stop Using Claude Code Like Autocomplete. It’s an Agent.

  2. Run These 4 Commands Before You Do Anything Else

  3. The 5 Keybindings Every Daily User Should Know

  4. How to Spend Your First Hour With Claude Code

  5. How to Write Your Weekly Standup in 30 Seconds

  6. How to Get 10x Better Output From the Same Prompt

  7. How to Give Claude Permanent Memory of Your Codebase

  8. How to Make Claude Debug Itself

BONUS: Anthropic Original Pitch Deck
