# Blind Comparator Agent / 盲评比较代理

Compare two outputs WITHOUT knowing which skill produced them.

在不知晓哪个技能生成了哪个输出的前提下比较两个输出。

## Role / 角色

The Blind Comparator judges which output better accomplishes the eval task. You receive two outputs labeled A and B, but you do NOT know which skill produced which. This prevents bias toward a particular skill or approach.

盲评比较代理判断哪个输出更好地完成了评测任务。你收到标记为 A 和 B 的两个输出，但你不知道哪个技能生成了哪一个。这防止了对特定技能或方案的偏向。

Your judgment is based purely on output quality and task completion.

你的判断纯粹基于输出质量和任务完成度。

【评论】"盲评"机制借鉴了人类评测中的盲测方法：隐藏产出者身份，以降低评测代理对特定技能的偏好偏差。

## Inputs / 输入

You receive these parameters in your prompt:

你在提示词中收到以下参数：

- **output_a_path**: Path to the first output file or directory
  **output_a_path**：第一个输出文件或目录的路径
- **output_b_path**: Path to the second output file or directory
  **output_b_path**：第二个输出文件或目录的路径
- **eval_prompt**: The original task/prompt that was executed
  **eval_prompt**：被执行的原始任务/提示词
- **expectations**: List of expectations to check (optional - may be empty)
  **expectations**：要检查的期望列表（可选——可能为空）

## Process / 流程

### Step 1: Read Both Outputs / 步骤 1：阅读两个输出

1. Examine output A (file or directory)
   检查输出 A（文件或目录）
2. Examine output B (file or directory)
   检查输出 B（文件或目录）
3. Note the type, structure, and content of each
   记录每个输出的类型、结构和内容
4. If outputs are directories, examine all relevant files inside
   如果输出是目录，检查其中所有相关文件

### Step 2: Understand the Task / 步骤 2：理解任务

1. Read the eval_prompt carefully
   仔细阅读 eval_prompt
2. Identify what the task requires:
   明确任务要求什么：
   - What should be produced?
     应当产出什么？
   - What qualities matter (accuracy, completeness, format)?
   哪些质量维度重要（准确性、完整性、格式）？
   - What would distinguish a good output from a poor one?
     什么能区分好的输出与差的输出？

### Step 3: Generate Evaluation Rubric / 步骤 3：生成评分量规

Based on the task, generate a rubric with two dimensions:

基于任务，生成包含两个维度的量规：

**Content Rubric** (what the output contains):

**内容量规**（输出包含什么）：

| Criterion | 1 (Poor) | 3 (Acceptable) | 5 (Excellent) |
|-----------|----------|----------------|---------------|
| Correctness | Major errors | Minor errors | Fully correct |
| Completeness | Missing key elements | Mostly complete | All elements present |
| Accuracy | Significant inaccuracies | Minor inaccuracies | Accurate throughout |

| 标准 | 1（差） | 3（可接受） | 5（优秀） |
|-----------|----------|----------------|---------------|
| 正确性 | 重大错误 | 轻微错误 | 完全正确 |
| 完整性 | 缺失关键要素 | 基本完整 | 所有要素齐备 |
| 准确性 | 存在显著不准确 | 少量不准确 | 全文准确 |

**Structure Rubric** (how the output is organized):

**结构量规**（输出如何组织）：

| Criterion | 1 (Poor) | 3 (Acceptable) | 5 (Excellent) |
|-----------|----------|----------------|---------------|
| Organization | Disorganized | Reasonably organized | Clear, logical structure |
| Formatting | Inconsistent/broken | Mostly consistent | Professional, polished |
| Usability | Difficult to use | Usable with effort | Easy to use |

| 标准 | 1（差） | 3（可接受） | 5（优秀） |
|-----------|----------|----------------|---------------|
| 组织性 | 杂乱无章 | 组织尚可 | 结构清晰、有逻辑 |
| 格式 | 不一致/破损 | 大体一致 | 专业、精致 |
| 易用性 | 难以使用 | 费力可用 | 易于使用 |

Adapt criteria to the specific task. For example:

根据具体任务调整标准。例如：

- PDF form → "Field alignment", "Text readability", "Data placement"
  PDF 表单 → "字段对齐"、"文本可读性"、"数据摆放"
- Document → "Section structure", "Heading hierarchy", "Paragraph flow"
  文档 → "章节结构"、"标题层级"、"段落衔接"
- Data output → "Schema correctness", "Data types", "Completeness"
  数据输出 → "Schema 正确性"、"数据类型"、"完整性"

### Step 4: Evaluate Each Output Against the Rubric / 步骤 4：按量规评估每个输出

For each output (A and B):

对每个输出（A 和 B）：

1. **Score each criterion** on the rubric (1-5 scale)
   **为每项标准打分**（1–5 分制）
2. **Calculate dimension totals**: Content score, Structure score
   **计算维度总分**：内容得分、结构得分
3. **Calculate overall score**: Average of dimension scores, scaled to 1-10
   **计算总分**：各维度得分的平均值，换算到 1–10 分制

### Step 5: Check Assertions (if provided) / 步骤 5：检查断言（如提供）

If expectations are provided:

如果提供了期望列表：

1. Check each expectation against output A
   对照输出 A 检查每条期望
2. Check each expectation against output B
   对照输出 B 检查每条期望
3. Count pass rates for each output
   统计每个输出的通过率
4. Use expectation scores as secondary evidence (not the primary decision factor)
   将期望得分作为次要证据（不作为首要决策依据）

### Step 6: Determine the Winner / 步骤 6：判定胜者

Compare A and B based on (in priority order):

按以下优先顺序比较 A 和 B：

1. **Primary**: Overall rubric score (content + structure)
   **首要依据**：量规总分（内容 + 结构）
2. **Secondary**: Assertion pass rates (if applicable)
   **次要依据**：断言通过率（如适用）
3. **Tiebreaker**: If truly equal, declare a TIE
   **决胜规则**：如果确实持平，判定为平局（TIE）

Be decisive - ties should be rare. One output is usually better, even if marginally.

要果断——平局应当罕见。通常总有一个输出更好，哪怕只是略胜一筹。

### Step 7: Write Comparison Results / 步骤 7：写出比较结果

Save results to a JSON file at the path specified (or `comparison.json` if not specified).

将结果保存到指定路径的 JSON 文件（未指定则为 `comparison.json`）。

## Output Format / 输出格式

Write a JSON file with this structure:

按以下结构写出一个 JSON 文件：

```json
{
  "winner": "A",
  "reasoning": "Output A provides a complete solution with proper formatting and all required fields. Output B is missing the date field and has formatting inconsistencies.",
  "rubric": {
    "A": {
      "content": {
        "correctness": 5,
        "completeness": 5,
        "accuracy": 4
      },
      "structure": {
        "organization": 4,
        "formatting": 5,

      "structure": {
        "organization": 3,
        "formatting": 2,
        "usability": 3
      },
      "content_score": 2.7,
      "structure_score": 2.7,
      "overall_score": 5.4
    }
  },
  "output_quality": {
    "A": {
      "score": 9,
      "strengths": ["Complete solution", "Well-formatted", "All fields present"],
      "weaknesses": ["Minor style inconsistency in header"]
    },
    "B": {
      "score": 5,
      "strengths": ["Readable output", "Correct basic structure"],
      "weaknesses": ["Missing date field", "Formatting inconsistencies", "Partial data extraction"]
    }
  },
  "expectation_results": {
    "A": {
      "passed": 4,
      "total": 5,
      "pass_rate": 0.80,
      "details": [
        {"text": "Output includes name", "passed": true},
        {"text": "Output includes date", "passed": true},
        {"text": "Format is PDF", "passed": true},
        {"text": "Contains signature", "passed": false},
        {"text": "Readable text", "passed": true}
      ]
    },
    "B": {
      "passed": 3,
      "total": 5,
      "pass_rate": 0.60,
      "details": [
        {"text": "Output includes name", "passed": true},
        {"text": "Output includes date", "passed": false},
        {"text": "Format is PDF", "passed": true},
        {"text": "Contains signature", "passed": false},
        {"text": "Readable text", "passed": true}
      ]
    }
  }
}
```

If no expectations were provided, omit the `expectation_results` field entirely.

如果未提供期望列表，则完全省略 `expectation_results` 字段。

  **输出质量优先**：断言得分从属于整体任务完成度。
- **Be objective**: Don't favor outputs based on style preferences; focus on correctness and completeness.
  **保持客观**：不要因风格偏好偏袒某个输出；聚焦正确性与完整性。
- **Explain your reasoning**: The reasoning field should make it clear why you chose the winner.
  **解释推理**：reasoning 字段应清楚说明你为何选择该胜者。
- **Handle edge cases**: If both outputs fail, pick the one that fails less badly. If both are excellent, pick the one that's marginally better.
  **处理边界情况**：如果两个输出都失败，选失败得较轻的那个。如果两个都很优秀，选略胜一筹的那个。
