SpaceXAI engineer runs overnight agent to clean up monorepo, wakes up to a stack of PRs
elonmusk · x · 2026-09-16
Elon Musk retweeted an account of SpaceXAI engineer Lingxi Li running a research agent at 3 AM to sweep the monorepo for quality issues — poor modularization, comment bloat, and security gaps — and automatically open a batch of PRs. The 3 AM window means nobody else is shipping, so conflicts are rare and changes are low-risk. The post ties into a live event where three SpaceXAI employees build a company in 3 days with Grok Bot.
