How I Built a Skill That Makes All My Other Skills Better (Using Karpathy's Autoresearch)

TLDR: The author runs 20+ Claude Code skills for their newsletter pipeline and noticed 70-80% of outputs were good but the rest missed the mark. They adapted Andrej Karpathy's open-source "autoresearch" pattern — give an AI something editable, a way to measure improvement, and a time box — into a meta-skill that autonomously improves all their other skills. The key innovation is converting subjective 1-5 rubric scores into binary yes/no checks so the loop can run without human judgment in the middle.
