-# Auth Token Compatibility + Refresh Singleflight Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** 兼容云 Supabase 实际 access token claims（缺失 `iss` 仍可通过），并修复前端 401 导致 refresh 风暴问题，消除日志中的批量 401/429 警告。
-
-**Architecture:** 后端保持 HS256 签名校验、`exp/sub` 必检，将 `iss` 从“强制存在”改为“存在时校验”；前端在拦截器中加入 refresh 单飞与防重入，避免并发 401 触发多次 refresh 或 refresh 自递归。同步清理无效分支与冗余状态。
-
-**Tech Stack:** FastAPI, PyJWT, Flutter, Dio, flutter_test
-
----
-
-### Task 1: 后端 JWT claim 兼容化（无 `iss` 可通过）
-
-**Files:**
-- Modify: `backend/src/core/auth/jwt_verifier.py`
-- Test: `backend/tests/unit/core/auth/test_jwt_verifier.py`
-
-**Step 1: Write failing test**
-- 新增用例：token 不含 `iss`、但 `sub/exp` 与 HS256 签名合法时应验证成功。
-
-**Step 2: Run test to verify it fails**
-- Run: `cd backend && uv run pytest tests/unit/core/auth/test_jwt_verifier.py -q`
-
-**Step 3: Write minimal implementation**
-- `jwt.decode` 的 `require` 去掉 `iss`，仅保留 `sub/exp`。
-- 若 payload 中存在 `iss` 且配置了 issuer，则手动比对 issuer；不一致时报错。
-
-**Step 4: Run test to verify it passes**
-- Run: `cd backend && uv run pytest tests/unit/core/auth/test_jwt_verifier.py -q`
-
-### Task 2: 前端 refresh 单飞 + 防递归
-
-**Files:**
-- Modify: `apps/lib/core/api/api_interceptor.dart`
-- Test: `apps/test/core/api/api_interceptor_test.dart`
-
-**Step 1: Write failing tests**
-- 并发 401 时只调用一次 `onTokenRefresh`。
-- `/api/v1/auth/sessions/refresh` 自身 401 不触发 refresh 重试。
-
-**Step 2: Run tests to verify failures**
-- Run: `cd apps && flutter test test/core/api/api_interceptor_test.dart`
-
-**Step 3: Write minimal implementation**
-- 增加 `_refreshFuture` 单飞字段。
-- 非 refresh 请求命中 401 时 await 同一个 refresh future。
-- 对 refresh/logout 认证端点和已重试请求加短路，避免无限重入。
-
-**Step 4: Run tests to verify pass**
-- Run: `cd apps && flutter test test/core/api/api_interceptor_test.dart`
-
-### Task 3: 清理无效/旧分支并做回归验证
-
-**Files:**
-- Modify: `apps/lib/core/api/api_interceptor.dart`（移除无效重试分支）
-- Modify: `backend/src/core/auth/jwt_verifier.py`（删除不再使用的路径）
-
-**Step 1: Refactor cleanup**
-- 删除不再可达的分支与重复逻辑，保持行为不变。
-
-**Step 2: Full targeted verification**
-- Run: `cd backend && uv run ruff check src tests`
-- Run: `cd backend && uv run basedpyright`
-- Run: `cd backend && uv run pytest tests/unit/core/auth/test_jwt_verifier.py tests/unit/v1/users -q`
-- Run: `cd apps && flutter test test/core/api/api_interceptor_test.dart test/features/auth`
-
-**Step 3: Runtime spot-check**
-- Run: 登录拿 token 后请求 `/api/v1/agent/history`，确认不再因缺失 `iss` 返回 401。

+# AgentScope Agent Route Migration Handoff Plan
+
+## 1) Reconfirmed Objective
+
+- Keep external API paths unchanged under `/api/v1/agent/*`.
+- Replace internal run/resume/events runtime path with `core/agentscope` modules.
+- Use five modules only: `runtime`, `prompts`, `schemas`, `tools`, `events`.
+- Put AG-UI event conversion + persistence + Redis export in `events`.
+- Keep `/transcribe` under the same router prefix but independent from agent runtime.
+- Continue migration until legacy `core/agent` is removable.
+
+## 2) Current Progress Snapshot
+
+### Completed
+
+- Task 1 (schemas) finished:
+  - Added runtime-facing schemas in `core/agentscope/schemas/agent_runtime.py`.
+  - Exported aliases for compatibility (`AcceptedTaskResponse`, `TaskAcceptedResponse`, `TaskAccepted`).
+- Task 2 (events) finished:
+  - Added `events` module with AG-UI conversion, SSE encoding, Redis stream bus, pipeline, and store abstraction.
+  - Security fixes applied:
+    - Prevent reserved key overwrite in AG-UI codec.
+    - Sanitize SSE stream id.
+    - Support Redis bytes payload decoding.
+  - SSE now reuses AG-UI protocol encoder (`EventEncoder`) instead of custom JSON-only logic.
+- Task 3 (runtime adapter) finished:
+  - Added `AgentRouteRuntime` to emit internal events around orchestrator execution.
+  - Added step events for stage identification:
+    - `step.start/step.finish` for `intent`, `execution`, `report`.
+  - Error event payload no longer leaks raw exception text to clients.
+- Task 4 (route/service wiring) largely finished:
+  - `/v1/agent/router.py` now uses `core.agentscope.events.to_sse_event`.
+  - `/v1/agent/dependencies.py` queue tasks switched to `core.agentscope.runtime.tasks`.
+  - `/v1/agent/dependencies.py` stream reads switched to `RedisStreamBus`.
+  - `/v1/agent/service.py` enqueue payload now carries `owner_id` and extracted `user_token`.
+  - Added tests for runtime task entrypoint dispatch/validation.
+
+### In Progress / Not Finished
+
+- Task 4 review wrap-up:
+  - One review already returned PASS for spec compliance after fixes.
+  - Final quality/security confirmation for latest delta should be re-run once before moving to Task 5.
+- Task 5 (sessions/messages persistence ownership, cost/tokens/latency full persistence) not started.
+- Task 6 (remove `core/agent` and clean imports) not started.
+- Task 7 (frontend AG-UI contract and E2E validation) not started.

+## 4) Key References Used
+
+### In-repo references
+
+- Current agent route/service contracts:
+  - `backend/src/v1/agent/router.py`
+  - `backend/src/v1/agent/service.py`
+  - `backend/src/v1/agent/dependencies.py`
+  - `backend/src/v1/agent/repository.py`
+- Existing runtime/orchestrator basis:
+  - `backend/src/core/agentscope/runtime/orchestrator.py`
+
+### External reference project
+
+- DIVA-backend async stream/task patterns (for architecture guidance only):
+  - `/home/qzl/Code/DIVA-backend/src/diva/services/app/conversation/task_event_stream_service.py`
+  - `/home/qzl/Code/DIVA-backend/src/diva/services/app/conversation/tasks.py`
+  - `/home/qzl/Code/DIVA-backend/src/diva/utils/agui_events.py`
+
+### Protocol/framework references
+
+- AG-UI protocol skill docs (event naming/shape guidance)
+- AgentScope skill docs (`ReActAgent`, model/runtime usage)
+
+## 5) Next Execution Plan (Continue From Here)
+
+### Step A: Close Task 4 gates (quick)
+
+- Re-run targeted checks for the latest Task 4 code:
+  - `uv run pytest tests/unit/v1/agent/test_service.py tests/unit/core/agentscope/runtime/test_tasks.py tests/unit/core/agentscope/runtime/test_agent_route_runtime.py tests/unit/core/agentscope/events -q`
+  - `uv run ruff check src/v1/agent src/core/agentscope/runtime src/core/agentscope/events tests/unit/core/agentscope/runtime tests/unit/core/agentscope/events`
+  - `uv run basedpyright src/v1/agent src/core/agentscope/runtime src/core/agentscope/events tests/unit/core/agentscope/runtime tests/unit/core/agentscope/events`
+- Run one explicit code/security review pass on Task 4 final diff.
+
+### Step B: Execute Task 5 (persistence migration)
+
+- Implement `events.store` real persistence (replace `NullEventStore` path in runtime task assembly):
+  - persist sessions/messages from AG-UI wire events.
+  - include tokens/cost/latency fields.
+  - maintain session aggregates.
+- Add unit + integration tests for persistence correctness and aggregation.
+
+### Step C: Execute Task 6 (remove legacy core/agent)
+
+- Move remaining required data structures into `core/agentscope/schemas`.
+- Replace all `core.agent.*` imports in active code paths.
+- Delete `backend/src/core/agent/**` when no runtime path depends on it.
+- Add guard test to ensure no legacy imports remain.
+
+### Step D: Execute Task 7 (frontend contract validation)
+
+- Validate AG-UI event stream compatibility with current Flutter parser and bloc flow.
+- Run impacted frontend tests for chat/event handling.
+
+## 6) Risks and Notes
+
+- Workspace is currently dirty with many unrelated app/backend files; avoid mixing commits.
+- This handoff only tracks the AgentScope migration subset above.
+- `/transcribe` remains in `v1/agent/router.py` and intentionally independent.
+
+## 7) Resume Checklist (first actions next session)
+
+1. Read this handoff file.
+2. Re-run Task 4 final checks and review gates.
+3. Start Task 5 by replacing `NullEventStore` with real store implementation.
+4. Keep route contract stable (`/api/v1/agent/*`) until Task 7 is verified.

+# AgentScope Agent Route Migration Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Keep `/api/v1/agent/*` routes stable while fully replacing old `core/agent` runtime with `core/agentscope` runtime, AG-UI event pipeline, Redis streaming, and session/message persistence.
+
+**Architecture:** Route handlers remain under `v1/agent`, but all runtime behavior moves to `core/agentscope` across five modules (`runtime`, `prompts`, `schemas`, `tools`, `events`). The `events` module owns AG-UI conversion, persistence, and Redis stream publishing/reading. Runtime orchestrator emits internal events only, then delegates to `events.pipeline` for normalization, persistence, and transport.
+
+**Tech Stack:** FastAPI, SQLAlchemy async, Redis streams, Taskiq, AgentScope ReActAgent, LiteLLM proxy, Pydantic v2, pytest.
+
+---
+

+- Create: `backend/src/core/agentscope/schemas/agent_runtime.py`
+- Test: `backend/tests/unit/core/agentscope/schemas/test_agent_runtime_schemas.py`

+# 日视图改进设计
+
+**Date:** 2026-03-11
+**Status:** 已确认
+
+## 需求概述
+
+对日历日视图进行三项改进：
+1. 固定顶部头部
+2. 添加「今天」快捷按钮
+3. 双指缩放时间轴高度
+
+## 设计方案
+
+### 1. 固定顶部头部
+
+使用 `Stack` + `Positioned` 布局：
+- 外层 `Stack` 包含头部和可滚动内容
+- 头部使用 `Positioned` 固定在顶部 `top: 0`
+- 时间轴内容使用 `SingleChildScrollView` 可滚动
+- 头部高度：68px
+
+### 2. 「今天」按钮
+
+- **位置**：+ 号按钮左侧（`const Spacer()` 在返回和日期之间，+号和今天按钮靠近）
+- **样式**：
+  - 圆角按钮（`BorderRadius.circular(AppRadius.xl)`）
+  - 背景：`AppColors.messageBtnWrap`
+  - 文字：黑色，「今天」
+- **显示条件**：只有当 `_selectedDate` 不是今天时显示
+- **点击行为**：调用 `_goToToday()` 跳转到今天
+
+### 3. 双指缩放时间轴高度
+
+使用 `GestureDetector` 监听缩放手势：
+- `_hourHeight` 从 `const` 改为变量 `double _hourHeight = 34.0;`
+- 添加缩放状态变量：
+  ```dart
+  double _baseHourHeight = 34.0;
+  double _currentScale = 1.0;
+  ```
+- 缩放范围：0.5x ~ 2.0x（17px ~ 68px/小时）
+- 在 `_buildTimelineBoard()` 中使用 `_hourHeight` 动态计算高度
+
+## 实现计划

-# Calendar Metadata And API Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** 统一后端 `schedule-items` 与 Agent 日历卡片的 metadata v1 约束，并让前端日历模块完成真实 API 接入与 metadata 全字段渲染。
-
-**Architecture:** 后端以 `v1.schedule_items.schemas` 作为 metadata 单一真源，路由响应与 Agent 工具 payload 统一复用该结构。前端新增 Calendar API 数据层，使用 DTO 与领域模型映射驱动 UI；日历创建弹窗与详情页升级为可编辑/展示完整 metadata（location、notes、attachments、version）。
-
-**Tech Stack:** FastAPI, Pydantic v2, SQLAlchemy, Flutter, Dio, GetIt, widget/unit tests

+# 日历提醒字段与详情页对齐设计
+
+**Date:** 2026-03-11
+**Status:** 已确认
+
+## 目标
+
+- 修复日历事件详情页字段映射错误，去掉 raw metadata 直出
+- 新增可持久化的提醒字段（方案1）：`metadata.reminder_minutes`
+- 打通前后端和 AgentScope 工具调用链
+- 用前端本地通知实现系统提醒与震动
+
+## 数据契约
+
+### metadata 结构
+
+```json
+{
+  "color": "#4F46E5",
+  "location": "会议室A",
+  "notes": "带电脑",
+  "attachments": [],
+  "reminder_minutes": 15,
+  "version": 1
+}
+```
+
+### 字段规则
+
+- `reminder_minutes`: `int | null`
+- 取值范围：`0..10080`（0 表示准时提醒，10080 表示最多提前 7 天）
+- 兼容历史数据：缺失或 null 视为无提醒
+
+## 前端设计
+
+1. 模型层（`ScheduleMetadata`）新增 `reminderMinutes`
+2. 详情页：提醒时间改为结构化渲染
+   - null: `无`
+   - 0: `准时提醒`
+   - n: `开始前 n 分钟`
+3. 创建/编辑弹层新增提醒选项，默认值为 `15`
+4. 删除 metadata raw 原样渲染区块
+
+## 本地通知设计
+
+- 采用 Flutter 本地通知，调度时间：`startAt - reminderMinutes`
+- 创建/编辑成功：重建该事件通知
+- 删除成功：取消该事件通知
+- App 启动后：扫描未来事件并重建通知（补偿机制）
+
+## 后端与 AgentScope 设计
+
+1. `ScheduleItemMetadata` 增加 `reminder_minutes`
+2. service 继续走 `metadata -> extra_metadata`，不加新 DB 列
+3. AgentScope `calendar.write` 增加 `reminder_minutes` 参数
+4. CrewAI calendar tool 将 `reminderMinutes` 映射为 `metadata.reminder_minutes`
+5. calendar tool 回包增加 `reminderMinutes` 字段
+
+## 验证策略
+
+- 后端：schemas/service/agentscope 单元测试
+- 前端：calendar_api 与详情页渲染测试
+- 手动：创建提醒 -> 等待系统通知与震动 -> 更新/删除后确认调度变更

+# Calendar Reminder Metadata Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add `metadata.reminder_minutes` end-to-end (frontend/backend/AgentScope), fix detail-page field rendering, and enable local system reminders.
+
+**Architecture:** Keep calendar schema additive via `metadata` JSON (no new DB columns). Backend validates and persists `reminder_minutes`; AgentScope tools accept and pass reminder values; frontend parses/edits/displays reminder and schedules local notifications based on event time.
+
+**Tech Stack:** Flutter, FastAPI, Pydantic v2, AgentScope toolkit, pytest, flutter_test.
+
+---
+
+### Task 1: Backend metadata schema tests first
+
+**Files:**
+- Test: `backend/tests/unit/v1/schedule_items/test_schemas.py`
+- Modify: `backend/src/v1/schedule_items/schemas.py`
+
+**Step 1: Write failing tests**
+- Add tests for `reminder_minutes` accepted values (`None`, `0`, `15`, `10080`)

+**Step 2: Run tests to verify RED**
+Run: `uv run pytest backend/tests/unit/v1/schedule_items/test_schemas.py -q`
+Expected: FAIL for missing/invalid field support.
+
+**Step 3: Minimal implementation**
+- Add `reminder_minutes: int | None = Field(default=None, ge=0, le=10080)` to `ScheduleItemMetadata`
+
+**Step 4: Verify GREEN**

+
+### Task 4: CrewAI calendar bridge tests first
+
+**Files:**
+- Test: `backend/tests/unit/core/agent/test_mutate_calendar_event_tool.py`
+- Modify: `backend/src/core/agent/infrastructure/crewai/tools/create_calendar_event_tool.py`
+
+**Step 1: Write failing tests**

+# 首页图片选择功能设计
+
+## 1. 需求概述
+
+在首页聊天界面的加号按钮弹出的底部面板中，实现拍照和相册选择图片功能：
+- 最多选择 3 张图片
+- 图片预览显示在输入框上方
+- 图片可被取消移除
+- 点击发送后图片随文本一起发送到后端
+
+## 2. 技术方案
+
+### 2.1 依赖
+
+添加 `image_picker: ^1.0.7` 到 `pubspec.yaml`
+
+### 2.2 状态管理
+
+在 `HomeScreen` 中添加图片状态：
+```dart
+List<XFile> _selectedImages = [];  // 最多3张
+```
+
+### 2.3 图片选择逻辑
+
+修改 `home_sheet.dart`：
+- `image_picker` 选择图片（最多3张）
+- 返回选中的 `List<XFile>` 到 `HomeScreen`
+
+### 2.4 AG-UI 消息格式
+
+修改 `ag_ui_service.dart` 的 `_buildRunInput` 方法，支持多模态消息：
+
+```dart
+Map<String, dynamic> _buildRunInput({
+  required String content,
+  List<XFile>? images,
+}) {
+  final threadId = _threadId ?? _newUuid();
+  final runId = _nextId(_runIdPrefix);
+  
+  // 构建多模态内容块
+  final contentBlocks = <Map<String, dynamic>>[];
+  
+  // 添加文本
+  if (content.isNotEmpty) {
+    contentBlocks.add({'type': 'text', 'text': content});
+  }
+  
+  // 添加图片（Base64 编码）
+  for (final image in images ?? []) {
+    final bytes = await image.readAsBytes();
+    final base64 = base64Encode(bytes);
+    contentBlocks.add({
+      'type': 'image',
+      'source': {
+        'type': 'base64',
+        'media_type': 'image/jpeg',
+        'data': base64,
+      },
+    });
+  }
+  
+  return {
+    'threadId': threadId,
+    'runId': runId,
+    'state': <String, dynamic>{},
+    'messages': [
+      {
+        'id': _nextId('user_'),
+        'role': 'user',
+        'content': contentBlocks.length == 1 
+            ? (contentBlocks[0]['type'] == 'text' 
+                ? contentBlocks[0]['text'] 
+                : contentBlocks)
+            : contentBlocks,
+      },
+    ],
+    // ...
+  };
+}
+```
+
+## 3. UI 设计
+
+### 3.1 图片预览区
+
+位置：输入框上方，聊天消息区域下方
+
+```
+┌─────────────────────────────────────┐
+│           聊天消息区域               │
+│                                     │
+├─────────────────────────────────────┤
+│ ┌─────────┐ ┌─────────┐ ┌────────┐│
+│ │    ✕    │ │    ✕    │ │   ✕    ││  ← 预览区
+│ │  [图片]  │ │  [图片]  │ │ [图片] ││
+│ └─────────┘ └─────────┘ └────────┘│
+├─────────────────────────────────────┤
+│ [+] [     输入消息...          ] [发送]│
+└─────────────────────────────────────┘
+```
+
+### 3.2 样式规格
+
+| 元素 | 值 |
+|------|-----|
+| 预览卡片尺寸 | 80x80 dp |
+| 圆角 | `AppRadius.md` (12dp) |
+| 间距 | `AppSpacing.sm` (8dp) |
+| 取消按钮 | 24x24 圆形，红色背景，白色 X 图标 |
+| 边框 | 1dp `AppColors.slate200` |
+
+### 3.3 交互
+
+- 点击加号 → 底部弹出选择面板
+- 选择图片 → 预览区显示缩略图
+- 点击 X → 移除对应图片
+- 输入文本 + 有图片 → 点击发送发送组合消息
+
+## 4. 文件改动
+
+| 文件 | 改动 |
+|------|------|
+| `pubspec.yaml` | 添加 image_picker 依赖 |
+| `home_sheet.dart` | 实现拍照/相册选择 |
+| `home_screen.dart` | 添加图片状态、预览区 UI |
+| `ag_ui_service.dart` | 修改 _buildRunInput 支持多模态 |
+
+## 5. 测试要点
+
+- [ ] 选择 1-3 张图片正常显示
+- [ ] 选择超过 3 张时提示或限制
+- [ ] 图片可以成功移除
+- [ ] 发送消息时图片 Base64 正确编码
+- [ ] AG-UI 消息格式符合规范

+### Task 3: 修改 HomeScreen 添加图片预览区
+
+**Files:**
+- Modify: `apps/lib/features/home/ui/screens/home_screen.dart:1-820`
+
+**Step 1: 添加导入和状态变量**
+
+在文件顶部添加导入:
+```dart
+import 'package:image_picker/image_picker.dart';
+```
+
+在 `_HomeScreenState` 类中添加状态变量:
+```dart
+List<XFile> _selectedImages = [];
+```
+
+**Step 2: 添加图片预览 Widget**
+
+在 `_buildInputContainer` 方法之前添加:
+```dart
+Widget _buildImagePreview() {
+  if (_selectedImages.isEmpty) {
+    return const SizedBox.shrink();
+  }
+  
+  return Padding(
+    padding: const EdgeInsets.only(

+    ],
+  );
+}
+
+void _removeImage(int index) {
+  setState(() {
+    _selectedImages.removeAt(index);
+  });
+}
+```
+
+**Step 3: 修改 _buildInputContainer 调用位置**
+
+在 `_buildInputContainer` 调用之前插入图片预览:
+```dart
+// 在 build 方法中修改
+body: SafeArea(
+  child: Column(
+    children: [
+      _buildHeader(context),
+      Expanded(child: _buildChatArea(context, state)),
+      _buildImagePreview(),  // 添加这行
+      _buildInputContainer(context, state),
+    ],
+  ),
+),
+```
+
+**Step 4: 修改 _showBottomSheet 传递回调**
+
+将 `_showBottomSheet` 方法修改为:
+```dart
+void _showBottomSheet(BuildContext context) {
+  showModalBottomSheet(
+    context: context,
+    backgroundColor: Colors.transparent,
+    isScrollControlled: true,
+    builder: (context) => HomeSheet(
+      onImagesSelected: (images) {
+        setState(() {
+          // 限制最多3张
+          final remaining = 3 - _selectedImages.length;
+          if (remaining > 0) {
+            _selectedImages.addAll(images.take(remaining));
+          }
+        });
+      },
+    ),
+  );
+}
+```
+

+### Task 4: 修改 AgUiService 支持多模态消息
+
+**Files:**
+- Modify: `apps/lib/features/chat/data/services/ag_ui_service.dart:1-643`
+
+**Step 1: 添加 base64 导入**
+
+在文件顶部添加:
+```dart
+import 'dart:convert';
+import 'package:image_picker/image_picker.dart';
+```
+
+**Step 2: 修改 sendMessage 方法签名**
+
+修改 `sendMessage` 方法接受可选的图片参数:
+```dart
+Future<void> sendMessage(String content, {List<XFile>? images}) async {
+  final streamToken = ++_activeStreamToken;
+  final runInput = _buildRunInput(content: content, images: images);
+  // ... 后续代码不变
+}
+```
+
+**Step 3: 修改 _buildRunInput 方法**
+
+```dart
+Map<String, dynamic> _buildRunInput({
+  required String content,
+  List<XFile>? images,
+}) {
+  final threadId = _threadId ?? _newUuid();
+  final runId = _nextId(_runIdPrefix);
+  
+  // 构建多模态内容块
+  final contentBlocks = <Map<String, dynamic>>[];
+  
+  // 添加文本（如果有）
+  if (content.isNotEmpty) {
+    contentBlocks.add({'type': 'text', 'text': content});
+  }
+  
+  // 添加图片（如果有）
+  if (images != null && images.isNotEmpty) {
+    for (final image in images) {
+      final bytes = await image.readAsBytes();
+      final base64 = base64Encode(bytes);
+      contentBlocks.add({
+        'type': 'image',
+        'source': {
+          'type': 'base64',
+          'media_type': 'image/jpeg',
+          'data': base64,
+        },
+      });
+    }
+  }
+  
+  // 根据内容块数量决定消息格式
+  final messageContent;
+  if (contentBlocks.isEmpty) {
+    messageContent = '';
+  } else if (contentBlocks.length == 1 && contentBlocks[0]['type'] == 'text') {
+    // 纯文本使用简单格式（兼容现有逻辑）
+    messageContent = contentBlocks[0]['text'];
+  } else {
+    // 多模态消息使用内容块数组
+    messageContent = contentBlocks;
+  }
+  
+  return {
+    'threadId': threadId,
+    'runId': runId,
+    'state': <String, dynamic>{},
+    'messages': [
+      {'id': _nextId('user_'), 'role': 'user', 'content': messageContent},
+    ],
+    'tools': _buildTools(),
+    'context': <Map<String, dynamic>>[],
+    'forwardedProps': <String, dynamic>{},
+  };
+}
+```
+
+**Step 4: 修改 _sendMessage 方法传递图片**
+
+在 `home_screen.dart` 中修改 `_sendMessage` 方法:
+```dart
+Future<void> _sendMessage(BuildContext context) async {
+  final content = _messageController.text.trim();
+  if (content.isEmpty && _selectedImages.isEmpty) return;
+  
+  // 保存图片引用
+  final images = List<XFile>.from(_selectedImages);
+  
+  FocusScope.of(context).unfocus();
+  _messageController.clear();
+  
+  // 清除图片
+  setState(() {
+    _selectedImages.clear();
+  });
+  
+  await context.read<ChatBloc>().sendMessage(content, images: images);
+  // ... 后续代码不变
+}
+```
+
+**Step 5: 需要修改 ChatBloc 接口**
+
+检查 ChatBloc 的 sendMessage 方法签名，如果需要修改，添加 images 参数。
+
+Run: `grep -n "sendMessage" apps/lib/features/chat/presentation/bloc/chat_bloc.dart`
+
+根据结果修改 ChatBloc 和相关调用。
+
+**Step 6: 验证编译**
+
+Run: `cd apps && flutter analyze lib/features/chat/data/services/ag_ui_service.dart`
+Expected: No errors
+
+---
+
+### Task 5: 测试验证
+
+**Step 1: 运行 Flutter 分析**
+
+Run: `cd apps && flutter analyze`
+Expected: No errors
+
+**Step 2: 运行单元测试（如果有）**
+
+Run: `cd apps && flutter test`
+Expected: Tests pass
+
+---
+
+### 实施提示
+
+1. Task 2 和 Task 3 可以并行开发（HomeSheet 和 HomeScreen 独立）
+2. Task 4 需要在 Task 3 完成后进行，因为需要确定 ChatBloc 接口
+3. 如果遇到编译错误，检查 ImagePicker 是否正确导入
+4. AG-UI 格式可以参考: https://docs.ag-ui.com (如需要)
