Turn VS Code into an agent harness for customer-facing work.

A solution engineer’s output is a pipeline of artifacts — research, questions, findings, a data model, sample data, a rehearsed demo, a leave-behind. Every one of them can be produced, checked, or rehearsed by agents. This is a field manual for building that harness in VS Code, walked end-to-end through one engagement: Contoso Financial, a fictional Fortune-50 capital-markets firm, from discovery session to demo day.
