Agent Plugins Standardize Packaging for Skills and MCP Servers
Corey Ching presents Agent Plugins as an open specification for packaging agent skills and MCP server configurations in a format that can be discovered across products. Developed with AWS, Cursor, GitHub, Microsoft, OpenAI and Vercel, the standard defines a root manifest and common directory structure while leaving runtimes, permissions, marketplaces and client-specific interface choices to individual tools.
ChatGPT Plugins Combine Tool Access With Task-Specific Workflows
Corey Ching argues that ChatGPT plugins can turn connected work systems into task-specific workflows: apps such as email, cloud storage, calendars and Slack supply context, while skills structure it into an output. In the examples shown, that means producing editable Canva flyer drafts or assembling a sales brief that surfaces a customer’s pilot scope, security dependencies, owners and approval deadlines before a meeting.
ChatGPT Turns Plain-Language Briefs Into Published Web Apps
Corey Ching presents Sites as a ChatGPT plugin that turns a conversational brief into a functional web app, then lets users review, revise and publish it without leaving the interface. In the conference-site example, users give feedback in plain language or annotate the rendered page, while Sites handles implementation; Ching says built-in hosting and storage allow the finished app to be deployed directly. A companion Build Web Apps tool extends the same brief-driven approach to interactive software, illustrated with a locally running pixel-art game.
OpenAI Adds Workspace App Publishing to Codex
OpenAI’s Corey Ching presents Sites in Codex as a way for teams to turn prompts and trusted internal material into hosted applications that colleagues can use inside a workspace. The product is framed not as a document or slide generator, but as an application layer for internal dashboards, meeting-prep tools, event briefs, and decision memos, with hosting, authentication, storage, database support, sharing, and iterative refinement built into the workflow.
OpenAI Adds Team Sharing for Custom Codex Plugins
OpenAI says Codex plugins can now be shared across a workspace rather than remaining local to one user’s machine. The update lets creators distribute custom plugins to invited users or anyone in the workspace with a link, gives recipients a “Shared with you” area in the plugin directory, and adds direct share URLs for curated plugin pages. The company’s case is that recurring team workflows such as onboarding, pull-request preparation, and Slack triage can be packaged as Codex plugins and reused by teammates from inside the app.
