+Add locally installed OpenAI Codex plugins as one-click integrations: Messages
+(iMessage/SMS), Chrome, Computer Use, Computer History, and OpenAI Developer
+Docs. They appear in the connect dialog with their own icons, and a card that
+cannot run yet says what to install and links to it.
+
+Tool calls reach the plugins through `codex app-server` rather than a plugin's
+own MCP server, because their services only honour calls from a Codex host
+session. Computer Use and Chrome ship no MCP server at all, so their APIs are
+projected as typed tools — `list_apps`, `click`, `read_page`, `navigate` — that
+compile to a single call each. No model turn is involved; nothing is bundled or
+downloaded, and a machine without Codex simply sees the setup steps.
+
+A plugin's own approval prompt now reaches the caller, and states the terms it
+carries: a browser prompt that persists for a site says so. Approvals are asked
+once per session rather than per call.
+
+Elicitation requests can carry implementation-defined metadata through
+`FormElicitation` / `UrlElicitation`, and a paused execution reports it. Both
+fields are optional and additive.
