The second rung of Boris Cherny's 4-Step AI Maturity Framework, following Step 1 – AI Assisted (Pair Programmer Model). One engineer orchestrates 5–10 agents at once, each on its own work tree/git checkout, jumping between them and reviewing only final output rather than intermediate steps. The bottleneck this step removes is the lack of automated verification and safe agent permissioning — without those, reviewing only final output across many parallel agents isn't safe to do.
