🔬 New AI Craft
1. Claude Code lead: verification is the real skill in agentic coding
Boris Cherny, head of Claude Code at Anthropic, told YC Startup School 2026 that the craft is no longer prompt engineering but "give Claude a hard task that seems a little too hard, then make it possible for Claude to verify its work along the way" — calling verification the single most important thing most people get wrong. His team used exactly this loop to rewrite their Electron desktop app with Claude Code, taking it from sluggish to "pretty awesome."

2. Karpathy's 1M-token experiment: Opus 5 wrote 5,500 lines of code over 2 hours to render Lord of the Rings
Karpathy gave Opus 5 the first paragraph of LOTR, a 1M-token budget (~$10), and asked for a three.js render of the story — the model coded autonomously for ~2 hours and produced 5,500 lines of procedural animation code (playable demo at karpathy.ai/lotr-movie/). The experiment also exposes a weakness: LLMs can't natively perceive video or play games, so Opus 5 had to audit itself via slow screenshots and left plenty of jank — native multimodal feedback loops remain the missing capability.
