Knowledge router AND interactive teacher across every book-derived skill in this project. Two modes — (1) **ask**: auto-discovers all domain skills (finance, vuln hunting, AI security, red-teaming, personal growth, ...), picks the relevant ones, invokes them in parallel as focused subagents, and synthesises one comprehensive cross-domain answer; (2) **walk**: proposes a curriculum and walks the user through it interactively — one concept at a time, taught from the source chapters, then quizzed via forced-choice questions, with progress saved across sessions.
