ANTHROPIC LEAKED A $3.4M FILE THAT GIVES YOU A $120K/MONTH ENGINEERING TEAM IN 10 MINUTES AND BUILDS ANY SYSTEM
Microsoft and Google have been using this file for a while - 5 roles, zero hires, and it costs $0.
in 10 minutes the whole system is up: core, skills, contracts, tests, cron and a team already working.
all of it rests on the root you write: who buys, what it costs, what the team never does, and one metric.
Sonnet 5 brings up the core and wires the skills, Opus 5 splits the task and judges the result, Haiku 4.5 assembles the report on the batch queue.
contracts get written before the workers - without them every hop re-guesses what the last one meant.
with contracts the same object travels between all 5 roles: SETUP.md → skeleton → task graph → gate → report.
the critic is the gate - nothing ships past it, which is why you never get a green build with dead logic.
the auditor writes one line back into the root - tomorrow's team is better than today's, and you opened nothing.
without that edge you don't have a loop, you have 5 scripts repeating monday for a year.
4 typed handoffs and 1 return - the whole system rests on those five arrows.
save this and paste it into Claude Code - 10 minutes, 5 roles, zero hires ↓
