 name: setup-wiki
+author: ours
 version: 1.1.0
 description: Creates or migrates a project's `.wiki/` to the canonical Karpathy LLM Wiki layout — `CLAUDE.md` schema, `index.md`, `log.md`, `overview.md`, `raw/README.md`, plus empty `entities/`, `concepts/`, `packages/`, `sources/`, `contradictions/`, `open-questions/`. Use when the user says "set up wiki", "init wiki", "настрой вики", "инициализируй вики", "create wiki", "migrate wiki to canon", "wiki сломана", "wiki layout broken", or whenever `using-wiki` detects a missing or non-canonical `.wiki/`. Two modes — greenfield (no wiki) and migrate (existing non-canonical layout). Confirmation gate before writing. Cross-platform.
