openai/plugins took 505 stars in a day on a plugin manifest spec, not a product
GitHub Trending·medium signal
The repo is a curated set of Codex plugin examples at 6,072 stars and 813 forks, pushed 2026-09-08, where each plugin lives under plugins/<name>/ with a required .codex-plugin/plugin.json manifest. Optional companion surfaces are skills/, .app.json and .mcp.json, which effectively documents how Codex composes skills, apps and MCP servers into one installable unit. It is the second OpenAI first-party catalog on the trending boards this week, after openai/skills reappeared at +449.
