* feat: reviews page split view, add-to-chat, virtualization + perf
- Virtualize the diff (Pierre Virtualizer + worker pool), mirroring the agent
chat panel, so large PRs window rows instead of materializing every line.
- Split chat and diff into independent scroll containers and make chat
auto-scroll fully contained, so typing/streaming no longer moves the diff.
- Memoize FileDiffCard with stable callbacks so focusing a finding re-renders
only the affected card.
- Add a persisted unified/split diff toggle.
- Add highlight-to-chat: select lines (drag / shift-click) + gutter "+" to drop
a file:line snippet into the chat composer.
- Rebuild sidebar group rows: whole card scrolls to the group (incl. the
expanded explanation), Read explanation stays a separate toggle, memoized.
* feat: add-to-chat uses attachment pills + selection popup / ⌘L
Replace the raw-snippet injection with a Cursor-style flow:
- Selecting lines shows a floating "Add to Chat ⌘L" popup at the pointer; ⌘L
adds the current selection without it. Removes the auto-adding gutter "+".
- "Add to chat" now creates a removable attachment pill in the composer (and a
pill in the sent message bubble) instead of pasting raw text. The code is
still serialized into the message content so the model receives it as context.
* feat: restore gutter + drag-handle for line selection
Re-enable Pierre's gutter '+' as a click-and-drag line selector (with the
highlight growing as you drag) — the affordance that was lost when the
auto-adding gutter button was removed. It no longer auto-adds: the commit flows
through onLineSelected to the 'Add to Chat' popup / ⌘L.
* fix: live selection highlight while dragging + reposition Add to Chat popup
- Feed onLineSelectionChange into the controlled selection so rows highlight
live as you drag, not just on release (Pierre only paints the controlled
selection when the prop updates). Popup now fires on onLineSelectionEnd.
- Anchor the popup's bottom-left to the drag handle (drop horizontal centering)
so it no longer overlaps the '+' button.
* fix: anchor Add to Chat popup to gutter handle + click-away to unselect
- Position the popup from the gutter '+' handle's rect (in the diff shadow DOM,
placed on the selection's bottom line) instead of the pointer-release point,
which landed inconsistently. Falls back to the pointer if not found.
- Clear the line selection (and popup) on any outside pointer-down.
* fix: sidebar-collapse header overlap + PR review comments
- Lift useSidebarLayout to AgentsShell (single source), share collapsed via
context, and pad the reviews header left when the sidebar is collapsed so the
fixed collapse toggle no longer overlaps the header content.
- add-to-chat: collect each diff side separately so a selection that spans a
deletion->addition no longer pastes wrong-file lines (PR comment).
- chat: clear attachments after sending via a suggested prompt, so an attached
snippet isn't silently resent on the next message (PR comment).
* fix: anchored finding card positions to the right of the diff again
The virtualization refactor moved the card inside the main-width Virtualizer
scroller, so it clamped over the diff. Render it in the outer container as a
viewport-fixed card clamped to window width (right gutter / over the side panel,
like prod) and track the finding as the diff scrolls (rAF-throttled), hiding
when the finding scrolls out of view.
* feat: add UI hotkey wiring and Cmd/Ctrl+B sidebar toggle
Add a reusable useHotkey hook for registering global keyboard
shortcuts (with 'mod' resolving to Cmd on macOS, Ctrl elsewhere),
and wire up the first shortcut: mod+b toggles the left sidebar.

* fix: ignore key repeat for sidebar toggle hotkey
Holding Cmd/Ctrl+B fired repeated keydown events, toggling the sidebar
multiple times. Add an ignoreRepeat option to useHotkey and enable it for
the sidebar toggle so one held press toggles once.

The sidebar expand and collapse toggle buttons were missing the
cursor-pointer style, so hovering didn't show a pointer cursor.

* Make dashboard UI mobile-friendly
- Drop the thread title/repo header on the agent chat view.
- Expanded sidebar becomes a full-screen overlay on mobile (<768px) instead of a squished column; resize handle hidden.
- Default to collapsed on mobile first load so the chat stays visible; navigating a link/thread auto-collapses the overlay.
* Fix settings rows and run cards overflowing on small screens
- SettingsRow stacks label/control vertically below sm; reduce AppShell padding on mobile.
- Truncate long model/repo names in AgentRunCard metadata so cards stay within bounds.
* Keep collapsed-sidebar button from overlapping page titles on mobile
* Render page titles below the sidebar button on mobile instead of indenting
* Don't persist mobile auto-close to localStorage, preserving desktop preference

* feat(ui): add Agents chat UI ported from open-swe-app
Introduce a Cursor-style Agents surface separate from the dashboard, with ported chat/diff components and mock thread data until LangGraph APIs land.
Co-authored-by: Cursor <cursoragent@cursor.com>
* feat(dashboard): wire Agents UI to LangGraph thread APIs
Add dashboard thread list/detail/run/message/stream endpoints with a LangGraph message adapter, dashboard OAuth auth for runs, and TanStack Query hooks replacing mock data.
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(dashboard): single agent reply per turn in Agents UI
Use UUID thread IDs LangGraph accepts, skip confirming_completion for
dashboard threads, and merge adapter agent messages so duplicate bubbles
do not render.
Co-authored-by: Cursor <cursoragent@cursor.com>
* feat(ui): polish Agents UI with floating prompt and layout cleanup
Remove no-op chrome (git panel, headers, sidebar search), port CloudPromptBar
from open-swe-app, and refine chat layout so messages scroll behind the input.

* fix(agent): patch deepagents reducer for None messages on checkpoint replay
LangGraph thread state could 500 when cancelled runs left messages as None.
Apply the reducer guard before graph import, fall back to metadata in the
dashboard API, and adjust Agents prompt bar layout.

* feat(ui): unify sidebar user menu and clean up Agents UI navigation
Extract SidebarUserMenu so the dashboard and Agents sidebars render the
same profile button, drop the redundant Agents nav row in favor of the
existing Back to Agents link, add the open-swe logo header to the Agents
sidebar, flatten the New Agent button, and cap the home screen run list
to keep the prompt input in view.
* feat(ui): resizable/collapsible sidebar shared across dashboard and Agents
Add a useSidebarLayout hook + SidebarFrame wrapper so both sidebars
share a persisted width (default 260px, drag to resize, 200-420 range)
and a collapse toggle that hides the panel and surfaces a floating
reopen button. Also adds a DELETE /threads/{id} endpoint and an X-on-
hover thread delete control in the Agents sidebar.
* feat(ui): instant user message and busy indicator on Agents transition
Stash submitted prompts in sessionStorage, pre-populate the new thread
detail cache, and merge pending prompts into the rendered message list
so the Agents page renders the user bubble plus the existing thinking
spinner immediately instead of flashing a skeleton and "Agent is
starting" while the run boots.
* feat(ui): token-stream agent replies in the Agents thread view
Opt the LangGraph runs into messages-tuple streaming and forward those
events through the existing SSE channel. The frontend now applies
AIMessageChunk deltas directly to the cached thread (cancelling any
in-flight refetch first so optimistic tokens are not clobbered) and
keeps positional pending prompts so the user bubble stays in the right
place while the agent streams its reply.
* fix(dashboard): await threads.join_stream before iterating
threads.join_stream is async def returning an AsyncIterator, so it must
be awaited before async for. The SSE endpoint was raising
TypeError: 'async for' requires an object with __aiter__ method, got
coroutine on every connection.
* fix(dashboard): drop messages-tuple stream_mode that broke thinking-mode tool turns
Setting stream_mode=["values","messages-tuple","updates"] on
runs.create forces langchain_anthropic into streaming, and on the
second model call (after tool execution) its serialized thinking
blocks come back malformed, so Anthropic rejects the request with
'messages.1.content.0.thinking.thinking: Field required'. Revert to
the default stream_mode so claude-opus thinking + tool use runs to
completion. The frontend keeps the messages-event handler in place
as a no-op fallback for when streaming is re-enabled.
* feat(agents): per-thread model picker wired through to the run
Add optional model_id/effort to the create-thread and send-message
request bodies, forward them as agent_model_id/agent_effort in the
LangGraph run configurable, and record the resolved choice in thread
metadata so the UI can show the model the run is actually using.
get_agent now picks the per-thread override last (highest priority over
team default + profile override) and falls back gracefully when it is
absent or unsupported.
The frontend prompt bar becomes a controlled component fed by a
shared useModelOptions hook (options + profile -> defaultSelection).
AgentsHome seeds the picker from the user's profile default; the
thread view seeds from the thread's recorded model/effort and lets
each follow-up retarget the run.
* refactor(ui): align Agents prompt bar layout with open-swe-app PromptBar
Drop the absolute-positioned send button, restore the original
px-4 py-3.5 min-h-[106px] flex-col container, and move the model
picker into a mt-auto pt-2 footer row so the placeholder text and
the model selector share the same horizontal padding.
* chore: fix lint/format CI failures
Remove unused imports and reformat two files flagged by ruff.
* fix(tests): stop messages-reducer patch tests from polluting the suite
Restore agent modules after reducer patch tests and import LangSmithSandbox
from agent.server in proxy refresh tests so isinstance checks stay valid.
