Snippet of the day
"The first 100 customers are about you. The next 1000 are about your product. After that, it's about the system."
— Patrick Collison

Joke of the day

⚡ Builder's Note · Sneak peek of this week's guide
Most 'agentic AI' production systems are just LLM + retry-on-failure.
That's fine — but call it what it is. Real agents make decisions about WHAT to do next, not just retry until the previous step works. If your agent's decision tree has fewer than 3 branches, you have a script with extra steps.
→ The decision-tree depth audit is in this week's guide.
