3 Engineers Shipped a Product from Empty Repo in 72 Hours with Grok Bot: 433 PRs, Notes Open-Sourced
CurieuxExplorer · x · 2026-09-21
Three SpaceX engineers (Roshan Sadanani, Lauren Tan, Matt Palmer) built and launched a product from an empty repo in 72 hours, live on stream, using the Grok Bot agent platform — totaling 433 PRs. The experience is now distilled into an MIT-licensed repo, grokbot-field-notes.
Key playbook:
- One chief of staff: a single orchestrator bot through which every specialist bot is built, so it knows who does what
- One bot, one job: scope bots like job descriptions; split only when scope grows
- Drafts before sends: write access is earned, not granted
- No proof, no merge: the bot must reproduce the bug, fix it, and attach video evidence to the PR
- Four human gates only: migrations, deploys, money, permissions — everything else automated
The repo ships a drop-in AGENTS.md, ANTIPATTERNS.md with 40 documented on-air failures and fixes, nine role playbooks, and a failure log.
