Repository navigation
feat(chat): composer shortcuts, Cmd+Enter steer, and image attachments in the transcript - #8181
Merged
Merged
Conversation
- Cap the editor at 40vh so long text no longer pushes the send button out of the pane. - "/" focuses the composer in the active chat pane. - Up/Down recall sent messages; Down past the newest restores the draft. - Cmd/Ctrl+Enter sends and then steers the message once it is queued.
Adds an additive host-service attachments.read query that returns an image attachment's bytes. User messages render images as square thumbnails above the text bubble; an older host without the query falls back to the name badge.

- Cmd+Enter steer remembers the turn it targets and drops the steer if that turn ends or a different one starts, so it cannot cancel the next queued task. - Up/Down keeps the draft as editor state, so chips survive the round trip; the start/end caret check now handles a leading or trailing chip. - History skips harness bookkeeping blocks, like the transcript does. - "/" works in a new chat before the first message. - An image the browser cannot display falls back to the name badge.

Included review availability: This review used your included allowance. Your plan provides up to 10 included reviews per hour; 4 remain after this review.
The Claude and Codex harnesses dropped attachment parts, so an image never reached the agent. The composer now writes attached files into the worktree's .superset/attachments (the convention terminal pastes already use) and appends one tag per file to the message text: <attachment path=".superset/attachments/shot.png" type="image/png" /> Every harness gets the same plain path and reads the file with its own tools. The transcript, queue rows, history and rail parse the tags back out: images show as thumbnails read through filesystem.readFile (capped at 5 MB), other files as name badges. Drops the host-service attachments.read query this PR had added, and moves uploadPastedFiles to usePaneRegistry/utils now that the chat composer shares it with the terminal.
This reverts commit 42991c1.
- registerHistoryNavigation (PromptInput/utils/historyNavigation) holds the Up/Down logic that lived inline in ComposerBody, with headless Lexical tests: recall from empty, no recall mid-draft, a chip draft survives a round trip, and an edit to a recalled prompt is kept. - Once a recalled prompt is edited, Up/Down no longer navigate, so the edit is not discarded. Clearing the box resumes navigation. - chat-ui gets a test script and excludes tests from tsc, like packages/chat. - SessionView wraps the history list in useStableList so a new timeline item does not re-render the memoised Composer.
FOCUS_CHAT_INPUT (Cmd+J / Ctrl+Shift+J) and CHAT_ADD_ATTACHMENT (Cmd+U / Ctrl+Shift+U) were registered and listed in Settings but nothing handled them. The active chat pane's composer now does, through useHotkey, so both can be rebound. "/" stays a plain listener because a registry entry holds one binding per platform; it now also skips IME composition and AltGr like useHotkey does.
…s it
Cmd/Ctrl+Enter used to send the prompt, wait on the client for its queue
echo, then call steerQueuedPrompt: three client-side guards and still a
window where the turn could change between the check and the action.
promptInputSchema gains an optional steer: { expectedTurnId }. When
LiveSession.prompt queues the message and the running turn is still that
id, it steers it in the same step. Otherwise it only queues, as before.
Compatibility: additive optional input. Older clients never send it, so
behaviour is unchanged; an older host strips the unknown key and queues
the message normally. The outbox carries the flag so a retry sends it
again, and the desktop drops useSteerOnArrival and the runningTurnId prop.

Attachment tags are plain message text, so a typed tag could name any path, and filesystem.readFile does not check worktree containment. The parser now accepts only a single sanitized file name directly inside .superset/attachments, the only shape the composer writes. Any other tag stays in the message as text and is never read.

P2: When the workspace lookup fails or has no worktree path, the disabled file query remains pending and this renders an endless shimmer. Track the workspace query state and show the filename badge when loading cannot proceed.

P2: For sessions exceeding the initial page, Up-arrow history omits older prompts until the user scrolls the transcript to load them. Build history from a complete session source or page older entries independently.

P2: This case never sends a previously running turn ID: t0 is absent from GATED_THEN_QUICK, while t1 is still running. It won't catch steering when the expected turn has completed; complete t1, start t2, then send expectedTurnId: "t1" and assert the prompt stays queued.

P2: Keyboard shortcuts stop working when focus is on a row’s Steer, Remove, or More control because event.target is the nested control, not the row. Resolve the containing [data-queue-row] before looking up its index.

promptinput gains an optionalsteer. Older clients never send it, so behaviour is unchanged. An older host strips the unknown key (non-strict zod object) and queues the message without steering.Follow-ups
