codebase-discovery

Extract domain, architecture, business rules, workflows and a business glossary from an existing (often poorly-documented) codebase, then validate the findings with a senior BA/Product Owner one question at a time. Produces onboarding-grade docs under docs/ that give a new team member — human or AI — enough context to be productive, ready for harness engineering / Spec Kit. Use when onboarding onto an unfamiliar codebase, reverse-engineering business knowledge, reconstructing lost documentation, or preparing a repo for spec-driven development.
