# Context Optimizer - 上下文优化专家
## BenszAPI 任务工作区
本 Skill 的新任务中间文件统一写入 `./.bensz-api/task-{yyyymmdd-hhmm}-{简短描述}/{skill名}/input|output|log/`。同一任务复用一个任务根目录；多 Skill 协作才创建 `shared/`。正式交付物不写入该目录，历史隐藏目录只允许显式兼容读取、迁移或清理。
## 与 bensz-collect-bugs 的协作约定
- 因本 skill 设计缺陷导致的 bug，先用 `bensz-collect-bugs` 规范记录到 `~/.bensz-skills/bugs/`，不要直接修改用户本地已安装的 skill 源码；若有 workaround，先记 bug，再继续完成任务。
- 只有用户明确要求“report bensz skills bugs”等公开上报时，才用本地 `gh` 上传新增 bug 到 `huangwb8/bensz-bugs`；不要 pull / clone 整个仓库。
## 核心理念
**上下文优化** 是长对话性能的关键：
```
┌─────────────────────────────────────────────────────────┐
│ 识别问题 → 压缩历史 → 掩码加载 → 缓存重用 → 性能提升 │
└─────────────────────────────────────────────────────────┘
```
**核心问题**：
- ❌ **Lost-in-Middle**：关键信息被中间内容淹没
- ❌ **Context Poisoning**：冲突信息干扰判断
- ❌ **Distraction**：无关信息浪费 token
- ❌ **Context Clash**：多信息源冲突
---
## 何时使用本技能
在以下场景时激活：
- 长对话导致性能下降
- Context window 接近限制
- AI 遗忘之前的信息
- 提到"上下文"、"token 限制"、"效率"
---
## 上下文问题识别
### 问题 1：Lost-in-Middle
**表现**：
- AI 遗忘对话中间的关键信息
- 首尾信息记住，中间信息遗忘
- 需要重复提供相同信息
**检测**：
```python
def detect_lost_in_middle(conversation: list) -> bool:
"""检测是否出现 lost-in-middle 问题"""
# 1. 检查对话长度
if len(conversation) < 10:
return False
# 2. 检查是否有重复提问
questions = [msg for msg in conversation if '?' in msg]
unique_questions = set(questions)
if len(questions) > len(unique_questions) * 1.5:
return True # 存在重复提问
# 3. 检查中间内容是否被引用
middle_start = len(conversation) // 3
middle_end = len(conversation) * 2 // 3
middle_content = conversation[middle_start:middle_end]
# 检查后续对话是否引用中间内容
later_refs = sum(
1 for msg in conversation[middle_end:]
if any(keyword in msg for keyword in extract_keywords(middle_content))
)
if later_refs < len(middle_content) * 0.1:
return True # 中间内容被遗忘
return False
```
### 问题 2：Context Poisoning
**表现**：
- AI 产生矛盾的回答
- 错误信息影响判断
- 不同来源信息冲突
**检测**：
```python
def detect_context_poisoning(conversation: list) -> list:
"""检测上下文污染"""
conflicts = []
# 1. 提取所有事实陈述
facts = extract_facts(conversation)
# 2. 检测矛盾
for fact1, fact2 in combinations(facts, 2):
if are_contradictory(fact1, fact2):
conflicts.append({
'type': 'contradiction',
'fact1': fact1,
'fact2': fact2,
'severity': 'high'
})
# 3. 检测信息源冲突
sources = group_by_source(facts)
for source, source_facts in sources.items():
if has_internal_conflicts(source_facts):
conflicts.append({
'type': 'source_conflict',
'source': source,
'severity': 'medium'
})
return conflicts
```
---
## 优化策略
### 策略 1：压缩策略
#### 历史压缩
```python
class ContextCompressor:
"""上下文压缩器"""
def compress_history(
self,
conversation: list,
max_tokens: int,
retention_priority: list[str] = None
) -> list:
"""
压缩对话历史

# 1. 分类消息
categorized = self._categorize_messages(conversation)
# 2. 按优先级保留
retained = []
current_tokens = 0
for category in priority:
messages = categorized.get(category, [])
for msg in messages:

if current_tokens + tokens > max_tokens:
# 尝试压缩
compressed = self._compress_message(msg)
if current_tokens + self._count_tokens(compressed) <= max_tokens:
retained.append(compressed)
current_tokens += self._count_tokens(compressed)
else:

elif self._is_decision(msg):

else:

def _compress_message(self, message: str) -> str:
"""压缩单条消息"""
# 提取关键信息

return f"[摘要] {summary}"
def _count_tokens(self, text: str) -> int:
"""估算 token 数量"""
return len(text.split()) * 1.3 # 粗略估计
```
#### 增量摘要
```python
class IncrementalSummarizer:
"""增量摘要器"""
def __init__(self, summary_interval: int = 10):
self.summary_interval = summary_interval
self.summaries = []
def add_messages(self, messages: list) -> str:
"""添加消息并生成摘要"""
# 每隔 N 条消息生成一次摘要
if len(messages) % self.summary_interval == 0:

# 返回完整的摘要历史
return "\n\n".join(self.summaries)
def _generate_summary(self, messages: list) -> str:
"""生成消息摘要"""
# 提取关键信息
key_info = {

}
# 格式化摘要
summary_parts = []
if key_info['tasks']:

if key_info['outcomes']:

return " | ".join(summary_parts)
```
### 策略 2：掩码策略
#### 按需加载
```python
class LazyContextLoader:
"""懒加载上下文"""
def __init__(self):
self.loaded_references = {}
self.reference_metadata = {}
def load_reference(
self,
ref_name: str,
force: bool = False

# 已加载且不强制

return self.loaded_references[ref_name]
# 检查元数据
metadata = self.reference_metadata.get(ref_name)
if not metadata:
return None
# 按需决策
if self._should_load(metadata):
content = self._load_from_disk(ref_name)
self.loaded_references[ref_name] = content
return content
return None
def _should_load(self, metadata: dict) -> bool:
"""判断是否应该加载"""
# 判断逻辑：
# 1. 是否被明确请求
# 2. 相关性分数
# 3. 当前 token 使用率
relevance = metadata.get('relevance', 0)
token_usage = metadata.get('token_usage', 0)
return relevance > 0.7 or token_usage < 0.8
```
### 策略 3：缓存策略
#### 智能缓存
```python
class SmartCache:
"""智能缓存系统"""
def __init__(self, max_size: int = 100):
self.cache = {}
self.max_size = max_size
self.access_count = {}
def get(self, key: str) -> any:
"""获取缓存"""
if key in self.cache:
# 更新访问计数

return self.cache[key]
return None
def set(self, key: str, value: any, priority: int = 1):
"""设置缓存"""
# 缓存已满，清理低优先级项
if len(self.cache) >= self.max_size:
self._evict_low_priority()
self.cache[key] = value
self.access_count[key] = 0
def _evict_low_priority(self):
"""淘汰低优先级缓存"""
# 按 (访问次数 * 优先级) 排序
items = list(self.cache.items())
items.sort(key=lambda x: self.access_count.get(x[0], 0) * x[1].get('priority', 1))
# 移除最低分项
if items:
key_to_remove = items[0][0]
del self.cache[key_to_remove]
del self.access_count[key_to_remove]
# 使用示例
cache = SmartCache()
# 缓存解析结果
code_structure = parse_code('main.py')
cache.set('code:main.py', code_structure, priority=2)
# 获取缓存
cached = cache.get('code:main.py')
if cached:
use_cached_structure(cached)
```

## 优化检查清单
### 问题诊断
- [ ] 对话长度是否合理
- [ ] 是否有重复提问
- [ ] 中间信息是否被遗忘
- [ ] 是否存在信息冲突
### 压缩策略
- [ ] 历史对话已摘要
- [ ] 关键决策已保留
- [ ] 错误信息已保留
- [ ] 无关信息已过滤
### 掩码策略
- [ ] 参考文档按需加载
- [ ] 详细信息延迟加载
- [ ] 避免一次性加载所有内容
### 缓存策略
- [ ] 解析结果已缓存
- [ ] 频繁访问内容已缓存
- [ ] 缓存有淘汰机制
---
## 最佳实践
### 1. 分阶段处理
```python
# ❌ 一次性处理所有信息
def process_large_file(filename):
content = read_file(filename) # 可能很大
result = analyze(content)
return result
# ✅ 分阶段处理
def process_large_file(filename):
# 第一阶段：获取结构
structure = get_file_structure(filename)
# 第二阶段：按需加载
for section in structure.sections:
content = load_section(filename, section)
result = analyze_section(content)
return aggregate_results(results)
```
### 2. 渐进式信息披露
```python
# ❌ 一次性提供所有信息
def provide_context():
return """
这是项目的完整文档，包括架构、API、配置等...
（可能 10000+ tokens）
"""
# ✅ 渐进式披露
def provide_context():
return """
