great_cto

You already have the agent. This is everything around it. great_cto runs Claude Code as a pipeline of 70 specialist agents β€” an independent model checks each stage before the next builds on it, spending caps refuse rather than warn, and three decisions stay yours: what gets built, how, and whether it ships.
