The revision adds verification-before-fixing and named failure modes, matching Karpathy's push for agentic engineering.
Why now: The ten-rule template surfaced on X this week, alongside renewed attention on Karpathy's Sequoia Ascent 2026 talk and its pitch for agentic engineering.
Karpathy's CLAUDE.md template grew from four rules to ten this week, per TechTimes.
One builder credits the added rules with cutting Claude Code's error rate from 41 percent to 11 percent. That's a single anecdotal claim, not a benchmark, but the stakes are real for anyone running an agent loop unsupervised.
The new additions read as guardrails for an autonomous process, not prompting tips. They tell the agent to verify a bug before patching it, keep its dependencies honest, and name its own recurring failure modes. I've watched Claude Code spiral through exactly these loops in my own projects, and naming the failure mode is usually what pulls it back.
The bigger context is Karpathy's Sequoia Ascent 2026 talk. There he frames vibe coding as fine for throwaway scripts, but argues real software needs a harder discipline: agentic engineering. The context window is the lever, the LLM is the interpreter, and the job shifts to shaping intent and reviewing output.
My bet: this list forks into a dozen competing versions within weeks. Most keep the four rules that are easy to copy and drop the two that require naming failure modes you've watched your own agent hit.
