Specs rot. Running code doesn't. How I restructured my AI agent skills around live references

37+ min ago   (493+ words) When I started having Claude Code build new web tools, I handed it abstract specs: design conventions, component rules, forbidden patterns. It would read the spec, produce something plausible, and stop at 80% quality. The remaining 20% took rounds of corrections. After…...

Right Tool, Wrong Arguments: The Agent Failure Your Evals Wave Through

58+ min ago   (480+ words) Your agent picked the correct tool. It routed to refund_order when the user asked for a refund. Your eval suite went green. And then it issued a $4,200 refund on order #0 because the argument extraction fumbled and defaulted the ID to zero....
