Style Learning

Learn the writing style from the user's conversations and text samples, and reuse it in subsequent writing tasks.

Use Cases

• The user says "Remember my writing style" or "Write an XXX in my style"
• The user provides several of their own articles as samples
• Xiaodazi proactively identifies that the user has stable writing preferences

Workflow

Stage 1: Collect Samples

When the user provides text samples, extract style features:

输入：用户的 1-3 篇文本样本
  ↓
分析维度：
  - 语气：正式/半正式/口语/学术
  - 句式：长句偏好/短句偏好/混合
  - 用词：书面/通俗/专业术语密度
  - 结构：段落长度/转折词/列表偏好
  - 特殊习惯：口头禅/常用表达/标点习惯
  ↓
输出：风格画像（结构化 JSON）

Stage 2: Save the Style Profile

Save the style profile as a local file for reference in subsequent writing.

# 风格画像存储路径
~/.xiaodazi/styles/

# 文件格式
~/.xiaodazi/styles/{用户名}_default.json
~/.xiaodazi/styles/{用户名}_{场景名}.json  # 可按场景保存多套风格

Style Profile Structure：

{
  "name": "默认风格",
  "created_at": "2025-01-15",
  "updated_at": "2025-02-07",
  "sample_count": 3,
  "profile": {
    "tone": "半正式，亲切但不随意",
    "sentence_style": "短句为主，偶尔用长句做总结",
    "vocabulary": "通俗用词，避免学术术语，喜欢用比喻",
    "structure": "开头直入主题，段落短（3-5句），善用列表",
    "special_habits": [
      "喜欢用破折号做补充说明",
      "段尾常用反问句引发思考",
      "数字用阿拉伯数字不用中文"
    ]
  },
  "few_shot_examples": [
    {
      "context": "写产品介绍",
      "sample": "（截取的 200 字典型片段）"
    }
  ]
}

Stage 3: Apply the Style

During writing tasks, read the style profile and inject it into the prompt:

用户请求：「帮我写一篇关于 AI 的文章」
  ↓
读取风格画像 → 提取关键约束
  ↓
生成时遵循：
  - 语气：半正式，亲切
  - 句式：短句为主
  - 用词：通俗，多用比喻
  - 结构：开头直入主题，段落 3-5 句
  ↓
输出：符合用户风格的文章

Stage 4: Continuous Learning

Each time the user modifies the output or gives feedback, update the style profile:

• The user says "Too formal" → adjust tone to be more colloquial
• The user manually modifies the output → compare the differences and update preferences
• Automatically update the profile after accumulating 5+ instances of feedback

Command Reference

Save the style profile

mkdir -p ~/.xiaodazi/styles
cat > ~/.xiaodazi/styles/default.json << 'EOF'
{
  "name": "默认风格",
  ...
}
EOF

Read the style profile

cat ~/.xiaodazi/styles/default.json

List existing styles

ls ~/.xiaodazi/styles/

Output Specifications

• When analyzing style, use plain language (avoid linguistic terminology)
• After saving successfully, tell the user "I've remembered your writing style"
• When writing, do not mention "I'm using your style profile"; write naturally
• The user can say "switch to a formal style" to temporarily switch without affecting the saved profile
