According to monitoring by 1M AI News, OpenAI has announced the launch of a plugin system for its AI programming tool Codex, allowing Codex to seamlessly connect with the tools developers use daily. The first integrations include Slack, Figma, Notion, Gmail, and more.
Plugins are installable workflow bundles, with each plugin capable of packaging three types of components: Skills (prompts that describe 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 plugins curated by OpenAI in the Codex app’s plugin directory, while CLI users can access them via the /plugins command.
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 use a .codex-plugin/plugin.json manifest file as the entry point and support version management, permission policy configuration, and branding display. The self-service publishing feature for the official public plugin market is not yet available.
