Details

Inspired by an approach proposed by Michael Feathers in 2002, they compiled and released, in paper form, a Github Copilot agent workflow for handling Brownfield code more reliably.

They stated that the agents in the accompanying GitHub repo can be used right away, and the focus is on systematizing modification work in existing codebases.

The core idea is to make changes in Brownfield environments more reproducible through an agent-based procedure.
