🚨 Breaking: The guy who created Claude Code @bcherny just revealed how his team actually builds software with AI. And it’s not prompting. It’s a 5-layer operating system for AI-driven development. Most developers only use: • one Claude session • long prompts • manual reviews • sequential work Boris’s team does the opposite. They run Claude like a parallel engineering org. Here’s what he shared: 1. Parallel sessions (not one AI) They run 5–10 Claude instances at once. Each handles a different task. One writes code One reviews One tests One refactors Everything happens in parallel. 2. Persistent memory via CLAUDE.md They keep a shared CLAUDE.md in the repo. It stores: • past mistakes • architecture rules • coding conventions • verification steps Claude reads it every session. So the AI improves over time. 3. Custom AI subagents Instead of one Claude, they define roles: • backend-reviewer • migration-guard • code-simplifier • verify-app Each agent has a specific job. Like a real team. 4. Worktree isolation (true parallelism) Each agent gets: • its own git worktree • its own task • its own tests • its own PR No context collisions. No waiting. Just parallel execution. 5. Orchestration commands They use compound commands: /simplify → runs multiple reviewers in parallel /batch → launches dozens of agents → each opens a PR This enables: • large migrations • repo-wide refactors • automated reviews • parallel implementation The insight: This isn’t one AI assistant. It’s an AI engineering system. Parallelism Memory Custom roles Isolation Orchestration Stack them together and Claude stops behaving like a chatbot — and starts behaving like a team of engineers. This is what most people missed. They copied prompts. Boris built infrastructure. Bookmark this. This changes how you use Claude Code.

99% of people using Claude are doing it wrong. They’re prompting. Not building systems. Not automating GTM. Not printing leverage. Meanwhile, a small group is using Claude to run: • Full GTM workflows on autopilot • Sub-agents working 24/7 • MCP-powered systems that replace entire teams That’s the gap. So I spent 100+ hours building The Claude GTM Engineer’s Bible — everything you actually need: • 1300+ battle-tested prompts • Claude Code + WAT framework setup • MCP, agents, automations (step-by-step) • Real GTM systems you can deploy immediately Not theory. Execution. I’m giving it to only 500 people. Want it? Follow me Must (so I can dm) Rt + Like Comment “CLAUDE” I’ll DM it. Miss this → stay stuck prompting.
