Descriptions:
Riley Brown walks through the seven skills and plugins he uses daily inside Codex, OpenAI’s super app that combines chat, a coding agent, and document creation in a single interface. Brown manages a 1.5 million follower content operation and frames these skills as the practical building blocks of a fully AI-powered marketing team.
The video opens by clarifying the distinction between skills (markdown instruction files that teach the agent a repeatable task) and plugins (bundled skill sets with external integrations). Highlighted workflows include a YouTube research skill, a Readwise integration for pulling reading highlights into content drafts, an Excalidraw skill for auto-generating mind-map style video outlines, and Paper—an HTML-based diagramming tool with built-in MCP support designed specifically for AI agents. Brown also demonstrates sub-agent spawning, where the main Codex agent creates parallel workers (named Zeno and Hyens in the demo) to complete multi-step research tasks concurrently, cutting a workflow that took over ten minutes down significantly.
Brown notes that all of these skills transfer directly to Claude Code users, since the underlying skill file format is compatible. The video’s central argument is that assembling and customizing reusable AI workflows—rather than handling each marketing task manually—is what separates high-output creators in 2026. Instructions for downloading each skill are linked in the video description.
