How Claude Code learns from your project mistakes (and why that matters)

Following Rod Macbeth's post yesterday about Boris Cherny's X thread on Claude Code tips (https://www.skool.com/ai-marketing-insiders/claude-code-tips-from-the-creator?p=de65df2f). I explored the content with Claude. Many points focused on coding activities, but point 10 on learning with Claude stood out. I asked Claude to expand on how this actually works.

Today I had a practical example. My calendar times were showing 30 minutes off in my daily briefings. The fix took some back and forth, but what happened next was new.

Claude Code updated two things automatically:

The workflow node that caused the problem
Its own project documentation (CLAUDE md) with the lesson learned

So next time it encounters a similar datetime format issue in this project, it already knows the solution. The learning persists.

I have attached the summary it produced. The key insight for non-coders: Claude Code can build institutional memory for your specific project, not just fix individual problems. Also CLAUDE md is your most valuable asset to maintain.
