Multi-language systematic codebase analysis (Python, Java, JavaScript, TypeScript, SQL, PL/SQL, Rust) -- analyzes architecture, traces data flows, detects anti-patterns, and generates structured documentation for onboarding, architecture review, or code documentation. The Next Steps menu wires deep-dive output into downstream documentation generators (CLAUDE.md, codebase map, interface docs) as a technical-reference backbone.

Pure-architecture auditor. Finds missed unification opportunities (cross-cutting concerns scattered across call sites that should be a single layer) and wrong abstractions (god services, flag-soup functions, premature interfaces, leaky abstractions that should be inlined or decomposed). Reads .deep-dive/ output and produces report-only findings grounded in canonical theory (Metz's Wrong Abstraction, Beck's Tidy First, Fowler's bounded contexts, Gross's Locality of Behaviour).
