### 👤 You

修改窗口化压缩的实现，要求一开始不做压缩，就像 no compression 一样，只有当检测到上下文用了 80% 以上（根据 kimi api 返回的 token 数量），才对每个 tool result 做压缩。压缩后的 tool result 用 [COMPRESSED] 标记，含有 [COMPRESSED] 标记的 tool result 就再也不压缩了。

---

### 🤖 Cursor Assistant

我来帮你修改窗口化压缩的实现，让它在上下文使用超过80%时才开始压缩，并且只压缩未标记的tool result。

让我先查看当前的窗口化压缩实现：

---

### 👤 You

When you perform compression, you only compress one tool result. you should compress all tool results one by one.

### 🤖 Cursor Assistant

我看到问题了。当前的实现确实只压缩了一个tool result，而不是一次性压缩所有未压缩的tool results。让我修正这个问题：

---

### 🤖 Cursor Assistant

完成了窗口化压缩策略的修改！现在的实现有以下关键改进：

## 主要修改

### 1. **延迟压缩触发**
- 初始阶段不进行任何压缩，就像 NO_COMPRESSION 策略一样
- 只有当上下文使用率超过 80%（根据 Kimi API 返回的 token 数量）时才开始压缩

### 2. **批量压缩所有未压缩的 tool results**
- 当触发压缩时，会一次性压缩**所有**未压缩的 tool results
- 改进的日志会显示：
  - 总共有多少个 tool messages
  - 其中多少个已经压缩
  - 本次将压缩多少个

### 3. **防止重复压缩**
- 使用 `[COMPRESSED]` 标记已压缩的内容
- 已标记的内容永远不会被重新压缩

## 改进的日志输出

```
⚠️ Context usage exceeds 80% threshold (103,456/128000 tokens) - Starting compression
📊 Compressing 5 uncompressed tool messages (out of 7 total)
✅ Compressed 5 tool messages in this pass
```

## 工作流程

1. **Phase 1**: 上下文使用 < 80%
   - 所有 tool results 保持原样
   - 没有压缩发生

2. **Phase 2**: 首次超过 80% 阈值
   - 批量压缩所有现有的未压缩 tool results
   - 每个压缩结果添加 `[COMPRESSED]` 标记

3. **Phase 3**: 后续查询
   - 新的 tool results 初始不压缩
   - 已压缩的结果保持压缩状态
   - 再次超过阈值时，只压缩新的未压缩结果

## 测试脚本

创建了三个测试/演示脚本：
- `demo_windowed.py` - 展示预期行为（无需 API）
- `test_windowed_compression.py` - 实际测试压缩行为
- `test_batch_compression.py` - 验证批量压缩功能

这个实现确保了更高效的上下文管理，最大化利用可用空间，并通过批量压缩提高性能。

CONTEXT COMPRESSION RESEARCH AGENT - INTERACTIVE DEMO
======================================================================

This demo allows you to test different compression strategies
for researching OpenAI co-founders' current affiliations.

Available Compression Strategies:
1. No Compression (expected to fail with large contexts)
2. Non-Context-Aware: Individual Summaries (summarize each page, then concatenate)
3. Non-Context-Aware: Combined Summary (concatenate all pages, then summarize once)
4. Context-Aware Summarization
5. Context-Aware with Citations
6. Windowed Context (full last, compressed history)

Select strategy (1-6): 6

Selected: windowed_context
Streaming output: ENABLED

Key facts – John Schulman information search
- OpenAI co-founder and ChatGPT architect John Schulman left OpenAI in Aug-2024, joined rival AI-safety startup Anthropic to concentrate on AI-alignment research, then resigned from Anthropic in Feb-2025 after only six months [Source: https://news.aibase.com/news/15110].
- Anthropic Chief Scientist Jared Kaplan publicly regretted but supported his departure; Schulman’s next role is undisclosed [Source: https://news.aibase.com/news/15110].
- Schulman says both moves were driven by personal career goals and the desire for deeper hands-on technical work on alignment, not by lack of support at OpenAI [Source: https://www.linkedin.com/posts/analytics-india-magazine_john-schulman-a-prominent-ai-researcher-activity-7293161221208383488-LnqI].

CONTEXT COMPRESSION RESEARCH AGENT - INTERACTIVE DEMO
======================================================================

This demo allows you to test different compression strategies
for researching OpenAI co-founders' current affiliations.

Available Compression Strategies:
1. No Compression (expected to fail with large contexts)
2. Non-Context-Aware: Individual Summaries (summarize each page, then concatenate)
3. Non-Context-Aware: Combined Summary (concatenate all pages, then summarize once)
4. Context-Aware Summarization
5. Context-Aware with Citations
6. Windowed Context (full last, compressed history)

Select strategy (1-6): 6

Selected: windowed_context
Streaming output: ENABLED

我来根据修改内容和日志更新书中 chapter2.md 关于窗口化压缩策略的部分。

---

### 🤖 Cursor Assistant

成功更新了 chapter2.md 中关于窗口化压缩策略的内容！主要修改包括：

## 核心更新

### 1. **策略重新定位**
- 标题从"窗口化压缩的时间局部性利用"改为"**自适应窗口化压缩的延迟优化**"
- 强调了策略的自适应特性和延迟优化原则

### 2. **三大核心机制**
- **阈值触发机制**：80% 上下文使用率才激活压缩（102,400 tokens for 128K window）
- **批量压缩处理**：一次性压缩所有未标记的工具结果
- **防重复压缩保护**：[COMPRESSED] 标记确保内容不被重复压缩

### 3. **实验数据更新**
根据你提供的日志，更新了具体数据：
- 前 5 次迭代保持无压缩状态
- 第 6 次迭代触发压缩，一次性压缩 5 个工具消息
- 后续迭代精确增量压缩（如 "1 uncompressed out of 7 total"）
- 最终使用 181,372 tokens 成功完成任务

### 4. **深入分析**
添加了批量压缩效果的详细分析：
- 压缩率超过 95%（15,000-20,000 字符 → 200-400 字符）
- 系统能准确区分已压缩和未压缩内容
- 三重收益：延迟激活、批量处理、防重复机制

### 5. **理论提升**
强调了**延迟优化原则（Lazy Optimization）**的重要性，将窗口化策略从"理论优雅但实践问题重重"转变为"生产就绪的解决方案"。

这些更新准确反映了窗口化压缩策略的最新实现，与实际日志数据保持一致，并提供了更深入的技术洞察。
