hk-follow-breadcrumb

Consults existing breadcrumb analysis docs before exploring the codebase. Use this skill whenever the user asks about how a flow works, where something happens in the code, how to debug or test a specific area, what files are involved in a feature, or needs to understand the path data takes through the system. Also trigger when the user mentions 'where does X happen', 'how does Y work', 'trace this', 'what files handle Z', 'how to test this flow', 'debug this area', or when you're about to spawn multiple exploration subagents to understand a cross-cutting flow. Even if the user doesn't explicitly ask — if the task requires understanding how multiple layers connect (frontend → backend → worker → CLI), check breadcrumbs first. This is cheaper and more accurate than re-discovering the same information through code search.
