The head of Claude Code at Anthropic, Boris Cherny, shared Anthropic's internal Claude Code workflow publicly, triggering a massive viral response (2.5M views, 12K likes). The core practice: each team maintains a CLAUDE.md in git that logs every mistake Claude makes so it's never repeated, plus style conventions, PR templates, and architectural decisions — read at the start of every session. VentureBeat ran a dedicated article titled 'The creator of Claude Code just revealed his workflow, and developers are losing their minds.' Most actionable: the feedback loop principle — always give Claude a way to verify its own work (bash command, test suite, or browser test).
