On a 1.04-million-line legacy system, how aiXcoder used AI to complete a 1,093-line code iteration

A military energy enterprise, in collaboration with the aiXcoder team, used AI to complete a 1,093-line code change on an existing system with 1.04 million lines of code and 184 functional modules, in under 20 minutes total. The solution customizes a main agent, development expert agents, and quality assurance expert agents according to software engineering responsibilities; each subtask uses an independent context, and code review is performed by an independent role to avoid self-attribution bias. Models and data are fully deployed locally and never leave the intranet.
