Gymwasp's agentic code review factory, called The Mandible, processed 372 issues over 6 months with 65% merge-ready after one review round and a cumulative pass rate of 87%. Analysis of 12,000 review rounds across seven parallel reviewer lanes shows diminishing returns after round 2, with oscillation rather than convergence, and reveals that naive averaging understates true cost by 44% when including issues shipped with warnings.
An AI software factory is an automated system that queues coding tasks, provisions isolated workspaces for agents, verifies changes automatically, and routes decisions to humans at explicit merge gates. The key insight is that a single engineer with a coding agent can generate pull requests faster than a team can review them, making the bottleneck not code generation but absorption of output through proper infrastructure and gates.
