Both list SKILL.md skills, but they sit at different layers. The Hermes Skills Hub is Hermes Agent's native, first-party registry. GuildSkills is the cross-agent layer on top of the open standard — the same skills plus Cursor, Codex, Gemini CLI, OpenCode, Claude Code and 35+ more, with search, ranking and a multi-signal Quality Score. They're complementary.
