We ran a tiny one-shot experiment from a one-shot SWE-bench task with Claude Code to study the Context Engineering & Reuse Pattern: • 92 LLM calls invoked • ~2M input tokens • 13 minutes runtime • 92% prefix reuse rate With prefix caching, this single task drops from $6.00

The haters said that James Madison University didn't deserve a #CFBPlayoff slot over Notre Dame, Texas, or BYU. And they were correct. Honestly, great call by the haters.

I fully agree with @Teamsters. Self-driving trucks should *always* be supervised by a qualified professional to keep our roads safe. It’s a necessary partnership for America’s highways and economy.

There are ZERO good books on AI. It moves too fast, and the people who know the most are immersed in making it move faster (rather than writing), such that the books that exist are either old or wrong. Is there a BOOK that contradicts this view?
