The creator of Claude Code just revealed his workflow, and developers are losing their minds

Boris Cherny, creator of Claude Code at Anthropic, revealed his development workflow that uses 5 parallel AI agents and exclusively runs the slowest but smartest model, Opus 4.5. His approach transforms coding from linear programming to fleet management, achieving the output capacity of a small engineering team while maintaining a shared knowledge file that makes AI mistakes permanent lessons.

• →Cherny runs 5 Claude instances simultaneously in his terminal plus 5-10 more in browser, managing them like a real-time strategy game.
• →He exclusively uses Anthropic's slowest model Opus 4.5, finding that smarter models reduce human correction time despite slower generation.
• →His team maintains a CLAUDE.md file in their git repository that turns every AI mistake into a permanent rule for future sessions.
• →Custom slash commands and subagents automate repetitive development tasks, with /commit-push-pr being used dozens of times daily.
• →The workflow validates Anthropic's 'do more with less' strategy against competitors pursuing trillion-dollar infrastructure buildouts.
