According to 1M AI News, OpenAI has announced the launch of a plugin system for its AI programming tool Codex, allowing it to connect seamlessly with tools commonly used by developers. The initial integrations include Slack, Figma, Notion, and Gmail. Plugins are installable workflow bundles that can package three types of components: Skills (prompts that describe workflows for Agents 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 plugins curated by OpenAI through the plugin directory within the Codex application, while CLI users can access them via the /plugins command. The plugins support local development and distribution. Developers can quickly build plugin skeletons using the built-in @plugin-creator skill and manage local plugins through repository-level or personal-level marketplaces. Plugins are initiated with a .codex-plugin/plugin.json manifest file, supporting version management, permission policy configuration, and branding display. The self-service publishing feature for the official public plugin marketplace has not yet been opened.
