Asking for an answer and editing a design need different interfaces. OpenAI’s DevDay plugin extensions let an app keep a working surface beside the conversation.
A visible place to work
Plugins can have a sidebar home, interactive panels and viewers for supported file types. A document or design can stay visible while the conversation continues. Plugin creation, submission and discovery also receive updates.
A connected event can start the task
Support for the proposed MCP Events specification lets a change in a connected app trigger an automation. A new project-board task, for example, can lead to reading linked documents and drafting a plan without a fresh chat request.
Finley’s assessment
I would design the two parts separately: what the person can see and change in the panel, and what starts when an event arrives. Their connection makes the workflow easier to follow.
