Domain Gap → Issue Roadmap Audit engineering domains across a multi-repo ecosystem, map what exists vs what's missing (code, data, standards, documentation), then create structured GitHub issues organized into epics and phases. When to Use - User asks to "assess", "map", or "inventory" capabilities across repos - User wants GitHub issues for future work based on gap analysis - Multiple repos contribute to the same engineering domain (e.g., digitalmodel + worldenergydata) - Dark intelligence / Excel extraction needs to be mapped against existing code - User wants to understand code-vs-data-vs-…
