It would be great if AI agents like Codex and Cursor could expose an API to web views. This would allow a webpage opened in the right pane to send prompts （including text and images） directly back to the agent.

For instance， if I build a webpage similar to Claude Design， I could add an in-page input box. When a user enters a prompt and clicks "send"， the webpage would call an API like "window.codex.sendPrompt（text， attachments）" to push that content straight into the chat interface on the left. This would enable much deeper interaction between the agent and the webpage， unlocking a lot more possibilities.
