plugin Software development

AI coding assistants are more helpful in greenfield development than for modifying brownfield code — large, undertested, poorly-maintained systems that make up the majority of professional programming. This workflow follows Michael Feathers' workflow from 2002, applied in the context of agentic coding. This is the Claude Code plugin that delivers the [seven-phase brownfield surgery](https://zenodo.org/records/19640171) workflow as slash commands, subagents, and phase-aware hooks. This workflow is already published as a paper Zenodo titled [Agentic Code Surgery for Brownfield Systems](https://zenodo.org/records/19640171) by the author of this plugin.
