+# Phase 1: Input Collection
+
+收集用户输入的文本内容。
+
+## Objective
+
+- 获取用户输入内容（直接粘贴或文件路径）
+- 生成输入配置文件
+
+**注意**: 输出格式固定为 BBCode + Markdown 混合格式（论坛优化），无需选择。
+
+## Input
+
+- 来源: 用户交互
+- 配置: 无前置依赖
+
+## Execution Steps
+
+### Step 1: 询问输入方式
+
+```javascript
+const inputMethod = await AskUserQuestion({
+  questions: [
+    {
+      question: "请选择输入方式",
+      header: "输入方式",
+      multiSelect: false,
+      options: [
+        { label: "直接粘贴文本", description: "在对话中粘贴要格式化的内容" },
+        { label: "指定文件路径", description: "读取指定文件的内容" }
+      ]
+    }
+  ]
+});
+```
+
+### Step 2: 获取内容
+
+```javascript
+let content = '';
+
+if (inputMethod["输入方式"] === "直接粘贴文本") {
+  // 提示用户粘贴内容
+  const textInput = await AskUserQuestion({
+    questions: [
+      {
+        question: "请粘贴要格式化的文本内容（粘贴后选择确认）",
+        header: "文本内容",
+        multiSelect: false,
+        options: [
+          { label: "已粘贴完成", description: "确认已在上方粘贴内容" }
+        ]
+      }
+    ]
+  });
+  // 从用户消息中提取文本内容
+  content = extractUserText();
+} else {
+  // 询问文件路径
+  const filePath = await AskUserQuestion({
+    questions: [
+      {
+        question: "请输入文件路径",
+        header: "文件路径",
+        multiSelect: false,
+        options: [
+          { label: "已输入路径", description: "确认路径已在上方输入" }
+        ]
+      }
+    ]
+  });
+  content = Read(extractedFilePath);
+}
+```
+
+### Step 3: 保存配置
+
+```javascript
+const config = {
+  input_method: inputMethod["输入方式"],
+  target_format: "BBCode+MD",  // 固定格式
+  original_content: content,
+  timestamp: new Date().toISOString()
+};
+
+Write(`${workDir}/input-config.json`, JSON.stringify(config, null, 2));
+```
+
+## Output
+
+- **File**: `input-config.json`
+- **Format**: JSON
+
+```json
+{
+  "input_method": "直接粘贴文本",
+  "target_format": "BBCode+MD",
+  "original_content": "...",
+  "timestamp": "2026-01-13T..."
+}
+```
