bub vs skillhub

bub: Bub is a small Python agent runtime built on agents.md and Agent Skills, where every stage of a turn is a pluggy hook that plugins can override. Context is rebuilt from append-only tape records, and the same pipeline serves the CLI, Telegram and custom channels.; skillhub: SkillHub is iFlytek's self-hosted registry for agent skill packages, giving organizations a private place to publish, version, search and review skills behind their firewall. It has team namespaces with roles, audit-logged review, scoped API tokens, S3/MinIO storage and a CLI that installs skills into agents such as Codex.
