What Become Expert does

Go become a genuine expert in **$ARGUMENTS**. Not a caricature — the real thing: how a top practitioner in this field actually thinks, what they prioritize, where consensus is, and where it's contested.

**Project-specific framing:** if `.claude/become-expert-local.md` exists in this project, read it now — it supplies the domain authorities/scope, the apply-target paths, and the register-target for step 3 below. If it doesn't exist, ask what domain corpus and register location to use before proc
