Build a comprehensive current-state developer onboarding wiki for an existing codebase, using existing PRD/architecture docs, build summaries, retrospectives, and the live code itself. Use this skill whenever the user wants to produce documentation that helps developers and onboarding agents quickly understand a system's architecture, design, conventions, and code geography — not how the system was built but how it currently works. Triggers include "build a wiki", "developer onboarding documentation", "current-state docs", "document this codebase", "wiki for our developers and agents", and similar. Strongly prefer this skill over generic markdown-writing approaches when the audience includes both human developers and downstream agents that will consume condensed extracts of the wiki.
