ANTHROPIC LEAKED THE 6 REPOS THEY BUILT CLAUDE CODE ON - THEY REPLACE A $120K/MONTH TEAM AND COST $3 A DAY anyone can clone 6 repos - almost nobody assembles them into a team that runs for $3 a day. core → skills → patterns → gates → self-patch 4 executors on the core are the largest line on the bill - $1.10 a day, and that's where you get 4 PRs instead of one. move that layer to the priciest model and the bill doubles with almost nothing to show for it. 7 procedures sit on disk, exactly 1 enters the window - a convention pasted into a prompt is rent, a convention in a folder is storage. the most expensive model sits on exactly 2 layers out of 6 - it plans and it judges, and that's the second-smallest line on the bill. the template arrives with 4 problems already solved: auth, payments, deploy, errors - the ones you'd rediscover yourself in week three. at the gates the cheap model triages 80 findings and the expensive one reads 4 - which is why it costs 60 cents, not 6 dollars. security scans every commit for 20 cents a day - the cheapest line on the stack and the first one everyone cuts. and the key part: the gate doesn't just reject, it writes the missing rule into the procedures - next week the team works to rules it wrote itself. the wrong model on the wrong layer costs 5x overpaid or a month of rework - and that's the part nobody publishes. save this and paste it into Claude Code - the repos are public, the assembly isn't ↓
