Add ability to resume inactive sessions and automatically continue with new
session ID. Includes message merging for preserving conversation history,
UI improvements to allow sending during inactive state, and database schema
migration. close#87
Add a new ModelSelector component that allows users to choose specific model variants for different AI agents. This includes:
- ModelSelector UI component with agent-specific model options
- Model parameter propagation through API, RPC, and spawning layers
- Support for auto model selection (default behavior)
- Localization strings for English and Chinese
- Type definitions for model options per agent
Introduces a new message-window-store module to manage message state with
automatic windowing of visible and pending messages. This replaces manual
React Query cache operations with a centralized, observable state system.
close#39
Key changes:
- New MessageWindowState tracks visible/pending messages with size limits
- Automatic trimming of message windows (400 visible, 200 pending messages)
- Pending message buffering when user scrolls away from bottom
- Centralized status updates for optimistic messages
- Thread component simplified with forwarded scroll and pending callbacks
- Removes message count tracking from components
This improves performance for chats with many messages and provides a
cleaner separation of concerns between UI and state management.
Extract permission mode display logic into shared utilities for better reusability and maintainability. Add PermissionModeTone type and related helpers to centralize mode-based styling rules across components. Update components to use new PermissionModeOption type for consistent permission mode presentation.
Implements comprehensive session lifecycle management with user-friendly interactions:
Rename: Update session metadata.name via PATCH endpoint with conflict detection
Archive: Abort active sessions via DELETE endpoint with validation
Delete: Permanently remove inactive sessions with cascade cleanup
Backend:
- Store.deleteSession() removes session and cascade-deletes messages
- SyncEngine.renameSession() with concurrency error handling
- SyncEngine.deleteSession() with active session validation
- PATCH /sessions/:id for rename, DELETE /sessions/:id for delete
Frontend Components:
- RenameSessionDialog: Text input with auto-focus and error display
- SessionActionMenu: Modal with rename, archive, delete buttons
- ConfirmDialog: Reusable confirmation with error feedback
- SessionHeader: Menu button (⋮) triggering action menu
- SessionList: Long-press detection triggering item actions
Interactions:
- Long-press on session list items (500ms threshold) opens action menu
- Menu button in session header (non-Telegram environments only)
- Confirmation dialogs with descriptive warnings for destructive actions
- Real-time error display in dialogs on operation failure
- Haptic feedback on long-press via usePlatform hook
Accessibility:
- Keyboard support (Enter/Space) for long-press handler
- Focus management in RenameSessionDialog
- Proper ARIA labels and semantic HTML
Implements bidirectional sync of permission/model modes between CLI sessions and web app. Adds Codex-specific permission modes (read-only, safe-yolo, yolo) alongside Claude's modes. Web can now control CLI session state via RPC set-session-config handler, while CLI broadcasts state changes through keep-alive payloads. UI controls are flavor-aware, showing appropriate modes for Claude vs Codex vs Gemini. Type centralization in api/types eliminates circular dependencies.
Implement comprehensive worktree session support allowing users to spawn sessions in temporary git worktrees. Includes backend worktree management, full-stack integration, and refined UI for session type selection.
Backend:
- Add worktree creation/removal utilities with branch management
- Track worktree metadata (basePath, branch, name, path) in session metadata
- Automatic cleanup of worktrees when sessions fail or exit
- Enhanced error handling with stderr tail logging
UI improvements:
- Redesign session type toggle with improved alignment and spacing
- Move worktree description inline with label for cleaner layout
- Add branch name input field that appears when worktree mode selected
- Auto-focus on worktree input when switching modes
- Reduce gap between radio options from gap-3 to gap-1.5
- Update descriptive text and placeholders for clarity
Integration:
- Thread worktree parameters through API client, RPC handlers, and daemon
- Add worktreeEnv utility to read worktree info from environment
- Update session spawning to support both simple and worktree modes
Implements comprehensive ACP backend enabling integration with ACP-compliant agents like Gemini. Includes stdio transport, message handling, permission flow, and registry for agent management. Adds new 'hapi gemini' command to launch ACP agent sessions.
Replace manual state management with TanStack Query (React Query) for more robust server state handling. This refactoring introduces:
- New hooks for queries: useSessions, useSession, useMessages, useMachines
- New hooks for mutations: useSendMessage, useSessionActions, useSpawnSession
- Centralized query client with optimized configuration (5s staleTime, disabled window focus refetch)
- Query key factory for consistent cache invalidation
- Improved message synchronization via socket events with cache updates
- Optimistic updates for message sending with retry capability
- Simplified App.tsx by removing manual state management logic
- Integrated React Query devtools in development mode
This enables automatic cache management, better error handling, and a foundation for more sophisticated data fetching patterns.
