Documentation & Modernization

Two complementary workflows for a repository the user already has checked out locally, bundled as one skill:

• Documentation mode — produce one definitive, cited architecture document from the code on disk. Ideal for onboarding, system-design maps, or as the evidence base for a modernization effort.
• Modernization mode — turn that architecture into a phased, safety-laddered plan to upgrade, migrate, or rewrite a legacy system.

Mode selection

• If the user wants to understand, document, map, research, or onboard onto a codebase, run Documentation mode.
• If the user wants to modernize, migrate, upgrade, or rewrite a system, run Modernization mode. Modernization mode is self-sufficient: if no architecture document exists yet, it runs the Documentation mode workflow first (in the same pass), then continues straight through to the plan.
