OpenAI Codex Plugin System Launch: Out-of-the-box Integration with Slack, Figma, Notion, Gmail

According to 1M AI News, OpenAI has announced the launch of a plugin system for its AI programming tool Codex, enabling Codex to seamlessly connect to developers' everyday tools. The initial integrations include Slack, Figma, Notion, Gmail, and more.

A plugin is an installable workflow bundle that can package three types of components: Skills (keywords describing workflows for the agent to discover and invoke as needed), Apps (application integrations or connector mappings), and MCP Servers (remote tools or shared contexts). Users can browse and install officially curated OpenAI plugins through Codex's in-app plugin directory, while CLI users can access them using the /plugins command.

Plugins support local development and distribution. Developers can quickly build plugin skeletons using the built-in @plugin-creator skill, manage local plugins through repository-level or personal-level marketplaces. Plugins use a .codex-plugin/plugin.json manifest file as an entry point, supporting versioning, permission policy configuration, and branding. Self-publishing on the official public plugin marketplace is not yet available.
