met an anthropic engineer making $1.2M a year. asked him how he ships alone at the pace of a full team. he didn't answer. sent me his .claude/. one folder. SAME MODEL - DIFFERENT RESULT. everyone's still picking between opus and sonnet like the model is the ceiling. it isn't. the real lever is what the model wakes up into: CLAUDE.md → hooks → verifier subagent → skills → mcp → memory → shift notes. you stop chatting with the model. you write the folder once. the folder runs the model. - CLAUDE.md - the contract - settings.json - the permissions - hooks/ - the reflexes - agents/verifier - the shift-notes cop - skills/ - 33 muscle memories - .mcp.json - the tools - MEMORY.md - the shift log that's the stack. full breakdown in the article below. bookmark before he realizes i posted it.
