Why Does AI Code Fail When Chained Together?

Each AI-generated module passes its own tests, reads cleanly, and does what the prompt asked. Then you wire three of them together and the system breaks in ways no single piece explains. That is the composition cliff: every generation session makes its own quiet assumptions about formats, nulls, retries, ordering, and ownership, and those assumptions never get reconciled with each other. As builders move from single-file help to multi-agent pipelines and AI-built services that call other AI-built services, this cliff has become where most production failures actually happen.
