Restore expired sessions via summary-based catch-up (#52)
Aksel Joonas ReediUnverified signatureWhen the backend loses a session (typically: HF Space restarted), the chat now shows a small inline banner instead of silently erroring: Where were we? Let me skim the conversation so far and pick up right where we left off — or we can start something new. [ Catch me up ] [ Start fresh ] Flow, in one pass: * Frontend stashes the raw backend messages in localStorage on every mount-hydrate and turn_complete. When the backend 404s for the session id, the SSE transport and the mount effect both fire onSessionDead → the session is flagged `expired` in sessionStore; the sidebar marks it "needs a catch-up". * Catch me up → POST /api/session/restore-summary with the cached messages. Backend creates a fresh session, runs the existing summarizer (factored into summarize_messages() and shared with in-session compaction) with a restore-specific prompt that preserves the tool-call trail, and seeds the new session with that summary wrapped in a [SYS…962191f -
Fix parallel-research display: per-call stats in CLI and web UI (#49)
Aksel Joonas Reedi +1: lee101Unverified signatureWhen multiple research sub-agents ran concurrently, the CLI collapsed them into a single flickering slot and every web-UI tool card showed the aggregate across all agents — so 3 parallel calls looked like 1. CLI (agent/utils/terminal_display.py): - Replace the global SubAgentDisplay singleton with SubAgentDisplayManager that tracks each agent by agent_id and renders one block per agent with independent (tool count · tokens · elapsed). - 4 rolling tool-call lines per agent (was 2). - When 2+ agents are live, switch to a compact one-line-per-agent layout (label + stats + most-recent tool). Detailed 4-line rolling view only when a single agent is active. Keeps the live region small enough to fit on one terminal page so cursor-up/erase doesn't drift when content would otherwise scroll into scrollback. - Clip every live-region line to terminal width (ANSI-aware) so a wrapped line can't corrupt the cursor-up math on narrow terminals. - On completion, erase the live block and f…5ab7c4e

Fix stuck 'Waiting for approval' spinner and improve table rendering
Clear waiting-approval activity status immediately when user approves, instead of waiting for the backend's tool_state_change event over SSE. Improve markdown table styles: horizontal overflow scroll, header background, better padding, and alternating row striping.70d2074

Persist research subtool steps across page refresh
Save research steps and stats to localStorage on every update, restore atomically with isProcessing on mount so the rolling display survives page refresh during active research.ccfb504 -
Fix stale approval dialog reappearing after page refresh
The message persist effect only triggered on message count changes, so approval state updates (which modify tool state within existing messages) were never saved to localStorage. On refresh, stale approval-requested state was restored. Now saves messages immediately after approval submission.9b1773a -

Replace multi-screen onboarding with single checklist view
Replaces the 4 separate onboarding screens with a unified checklist showing all steps (sign in, join org, start session) with live status. Adds org membership polling via new GET /auth/org-membership endpoint that reuses existing check_org_membership(). Join link opens as popup and auto-closes when membership is detected.6d7f53f -
Add message edit and regenerate from any point in conversation
Backend: add truncate_to_user_message() on ContextManager, POST /api/truncate/{session_id} endpoint, and session_manager.truncate() helper to slice conversation history to before a given user message. Frontend: add editAndRegenerate callback in useAgentChat that truncates backend + frontend messages then resubmits via existing chat flow. UserMessage gains an inline edit mode with pencil icon on hover, TextField for editing, Enter/Escape to confirm/cancel.0611031 -
Redesign research subagent display with live stats and rolling steps
- Add researchStats (toolCount, tokenCount, elapsed) to session state - Parse tokens:/tools: log events into stats instead of step list - Show live stats in chip (running · N tools · Xk tokens · Ys) - Rolling 2-line window of sub-tool calls, hidden on completion - Format step labels with specifics (dataset name, paper query, etc.) - Handle truncated JSON args from backend via regex fallback - Fix stale tool spinners on page reload (coerce to completed) - Clean activity status bar labels for research tool logs901a405

feat: beautiful research sub-agent UI with inline progress steps
- ToolCallGroup: renders research sub-steps inline below the tool row with contextual icons (📂 finding examples, 📄 reading file, 📚 docs) and a spinner on the active step - ActivityStatusBar: shows current research step in the shimmer bar ("Exploring docs(trl)..." instead of generic "Running research...") - Store: tracks researchSteps per-session, cleared on each new research call - useAgentChat: routes research tool_log events to both the step list and activity statusfff300b

feat: render cancelled tool state in UI after user interrupt
Send tool_state_change(cancelled) events for in-flight tools so the frontend can flip spinners to a muted "cancelled" state. Keep SSE stream open (don't call chat.stop()) so backend events arrive. Show "What should the agent do instead?" placeholder after cancel. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>887da19

fix: use backend is_processing as source of truth on refresh
Replace message-based state inference with the backend's is_processing flag. Message inference is fundamentally broken — completed tool results make tools look "done" even when the agent is mid-turn. Also add resume: true to useChat so the SDK calls reconnectToStream() on mount, re-subscribing to live events if the agent is still running. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>e229826 -
fix: auto-retry on truncated tool calls + correct activity status on refresh
Agent loop: when finish_reason=length drops tool calls, inject a system hint telling the LLM to use bash heredoc or smaller edits instead, then continue the loop. Also set max_tokens=16384 and emit an error event so the truncation is visible in the UI. Frontend: extract actual tool name from in-progress message parts on hydration instead of hardcoding 'running', which rendered as "Running running" in the activity bar.

fix: live event streaming after reconnection + LiteLLM timeout
Frontend: visibility change handler now re-hydrates messages, opens a live event stream via GET /api/events, and polls messages every 3s to keep the chat in sync. Terminal events trigger a final hydration and clean up both the stream and poll. Backend: add timeout=600 to litellm acompletion() call — long tool-use turns were being killed by the default timeout.

feat: SSE keepalive, reconnection, and is_processing flag
Prevents SSE streams from being killed by reverse proxies during long operations and lets the frontend recover gracefully after sleep/disconnect. Backend: - SSE keepalive pings every 15s via `: keepalive` comments - New GET /api/events/{session_id} subscribe-only endpoint for reconnection - is_processing flag on AgentSession, exposed in session info API Frontend: - reconnectToStream() re-attaches to a running session via /api/events - Visibility change re-hydrates ALL sessions from backend on wake - Background sessions also re-sync (removed isActive guard on listener) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>d7f2a7c -
fix: disable chat input during processing after page refresh
After hydrating messages from the backend, scan the last assistant message for in-progress tools (input-available state) or pending approvals and set the correct isProcessing/activityStatus. Previously the store defaults (idle) would briefly enable the chat input. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>0e75fdd -
fix: per-session state management for smooth task switching
Background sessions now maintain their own state snapshots in agentStore so streaming, tool calls, and panel updates are not lost when switching tasks or backgrounding the browser tab. - Add sessionStates map + updateSession/switchActiveSession/syncSnapshot - Side-channel callbacks always update per-session state (no isActiveRef guard) - Global setters (setPanel, setPanelView, etc.) sync to active snapshot - Re-sync state on browser tab visibility change - Fix direct state mutation in switchActiveSession Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>f56fa2e

feat: per-session WebSocket architecture for parallel chat sessions
Each session now owns its own useAgentChat + WebSocket transport instead of sharing a single instance. Background sessions process all events (including approval_required) continuously, fixing the bug where approvals from non-active sessions were silently dropped.
