Meta-repo pattern gives AI full codebase context without monorepo migration

A development team created a meta-repo that sits atop three separate platform repos, using symlinks to share AI skills, docs, and rules across iOS, Android, and KMP codebases. The setup reduced onboarding from three commands to one and enables cross-platform AI searches and audits. The pattern addresses the challenge of providing AI assistants with full context when merging repos isn't feasible.
