# feat\(web,mobile\): Continue on… a linked environment · PR \#16758 · pingdotgg/t3code [View on GitCafe](https://git.cafe/pingdotgg/t3code/pull/16758) Repository: [pingdotgg/t3code](https://git.cafe/pingdotgg/t3code) Visibility: public State: open Source repository: pingdotgg/t3code Source branch: t3code/peer/handoff-ui Target branch: t3code/peer/handoff Head commit: bae6ee0b2e3853df96ec3b279e68ca358169f2dc [Discussion and reviews](https://git.cafe/pingdotgg/t3code/pull/16758) [Commits](https://git.cafe/pingdotgg/t3code/pull/16758/commits?format=markdown) [Files changed](https://git.cafe/pingdotgg/t3code/pull/16758/diffs?format=markdown) ## Description --- Moving a thread to a linked environment ([#16751](https://github.com/pingdotgg/t3code/pull/16751)) was reachable only through the `t3_thread_handoff` MCP tool. Users had no way to start a move, see one waiting or under way, or reach the thread on the other machine afterwards. ## How - **"Continue on…" on every thread entry point.** - Web: the sidebar thread menu, the chat-header thread menu, and the command palette. The menus read `threadHandoff.options` as they open, waiting at most 1.5 s, and show one entry per linked environment. A target that can't take the thread is disabled with the reason, for example "Not answering right now." or the missing project. - Mobile: the thread row's long-press menu, the iOS thread header's git menu, and an Android header action. These open a small "Continue on…" sheet that reads the options, because native menus are built ahead of time. - The entry needs the `peerLinks` capability, is hidden while a move is under way or done, and is disabled while the thread runs. A running thread moves only through the agent (`t3_thread_handoff` with `whenTurnEnds`). - **The move's state above the composer**, from the shell's new `handoff` field, using shared wording (`threadHandoffNotice`): - pending: "Moving to when this turn ends", with **Keep it here**; - departing: "Moving to …"; - departed: "This thread continues on ", with **Open on **; - failed: the reason. While the thread is departing or departed, the composer is closed: web blocks sending with the reason, and mobile hides the composer behind the card. - "Open on " shows only when this client is also connected to that environment, so it never navigates to a thread the client cannot load. - `docs/user/remote-access.md` says where to find **Continue on…**. ## Verification - Web `threadActionMenu.logic` (19 tests) covers the new submenu: one child per target, disabled with its reason, disabled while running, disabled for a connection that cannot change threads, and absent with no targets. Client-runtime `peerLinks` (5 tests) covers `threadHandoffNotice` for pending, departed, failed and no move. - Mobile `thread-list-environments` (15 tests) still passes with the new `peerLinks` capability set. - A real move through the sidebar menu across two dev servers, in the recording below. - Web, mobile and client-runtime typecheck clean. Lint is clean on the changed files, apart from `ChatView.tsx`'s existing warnings. ## Screenshots ![Before (main) and after (this PR): the sidebar thread menu gains Continue on…, listing the linked environment](https://gh-file-drop-api-prod-mi5fy3sowv63ufte.pinglabs.workers.dev/f/ca5ab8bc4acb3354/16758-before-after.png) A real move from the sidebar menu.
