system-layer-extraction

Deep architectural investigation that extracts, documents, and maps every system in a codebase. Use this skill whenever the user asks to: extract layers, map systems, analyze architecture, investigate codebase structure, document system boundaries, create a system map, understand how systems relate, audit dependencies, assess isolation, or do any form of comprehensive architectural analysis. Also trigger when the user says things like 'I want to see all the layers', 'map out the systems', 'what are the moving parts', 'how is this structured', or 'give me the full picture of the architecture'. This is NOT for reviewing code quality or individual files — it's for understanding the full system topology.
