What is sync-dev?
Audits docs/specifications/, docs/issue/, and docs/policy/ for English documents that are missing a Korean translation in docs/dev/, or where the Korean version appears out of date compared to the English source, then creates or updates those translations. Use this to keep docs/dev/ in sync. Triggered by "sync docs", "번역 동기화", "update translations", "sync dev", or "mirror docs". Source: ywj3493/claude-skills.
