I made a clone of the workflow described by Dex Horthy in Advanced Context Engineering in the form of Claude Code Plugin where you can download at
https://github.com/billlyzhaoyh/humanlayer-clone.
It enables you to step through the three steps of using coding agent to accomplish complex tasks: research, plan and implement. This is also backed by a Linear based automation flow that you can follow the plug in to setup. The plugin will help you set up the github workflow if you wish or you can copy paste from my repo.
Let me know your thoughts and feedback!
