Code Atlas Skill Purpose Build exhaustive, regeneratable architecture atlases directly from code truth. A code-atlas is a living document set: diagrams, graphs, and inventory tables that form a navigable map of any codebase. Atlas-building is investigation: structured reasoning about code in graph form reveals structural bugs, API contract mismatches, and architectural drift that linear code review misses. An atlas is complete when any engineer, given only the atlas and a bug report, can trace the full execution path without opening the source code. Layer Overview Layer definitions are the si…
