The Upgrade Research Agent

"Our service calls parcelhttp with retry=3, streams large files through it, and runs on Python 3.8. What breaks if we upgrade from version 2.9 to version 3.0?"

An engineer typed that question into an internal tool. About two minutes later, the tool listed four changes that affect the code and one that does not. Every statement had a source beside it. Answering the same question by hand means reading a changelog, a migration guide and several issue threads, which takes most of an hour.

The library names in this design, such as parcelhttp, are illustrative and do not refer to real packages.
