About dominodatalab/domino-ai-plugin
One source tree, several distributions. This repository is a Claude Code plugin as checked in; the same checkout is a Codex / ChatGPT plugin (and builds the package for the OpenAI plugin directory), a Cursor plugin, a Gemini CLI extension, and an Antigravity plugin (plugin.json plus mcp_config.json). All of them share the same skills; all but the OpenAI directory package, which is skills-only, also carry the same always-on guidance and the same Domino MCP server.
