# Code Simplifier
提供代码简化、重构和优化的原则指导。
## 核心原则
### 函数设计
- **单一职责**: 每个函数只做一件事
- **长度控制**: 目标 < 50 行，理想 10-30 行
- **参数控制**: ≤ 4 个参数；超过时使用数据类或配置对象
- **早期返回**: 用 guard clauses 避免深层嵌套
### 代码组织
- **DRY**: 提取重复逻辑为公共函数
- **命名清晰**: 变量名反映意图，避免单字母（循环变量除外）
- **无魔法数字**: 提取为命名常量
- **嵌套控制**: 嵌套层级 ≤ 3 层
### 错误处理
- 捕获具体异常，不使用裸 `except:`
- 保留原始异常链 (`raise ... from e`)
- 使用 context manager 管理资源
## 语言特定规范
### Python
```python
# ✅ 类型注解
def process(user_id: int, data: dict) -> dict | None:
...
# ✅ list/dict comprehension（避免嵌套）
result = [x for x in items if x.condition]
# ✅ 命名
snake_case（变量/函数）, PascalCase（类）, UPPER_SNAKE_CASE（常量）
# ❌ 避免
# - 嵌套 comprehension
# - 过度使用 lambda
# - 裸 except:
```
### JavaScript / TypeScript
```javascript
// ✅ const/let，无 var
// ✅ 箭头函数
const process = (data) => data.filter(x => x.valid);
// ✅ 解构
const { name, email } = user;
// ✅ 命名
camelCase（变量/函数）, PascalCase（类/接口）, UPPER_SNAKE_CASE（常量）
```

humanizer
Remove signs of AI-generated writing from text. Use when editing or reviewing text to make it sound more natural and human-written. Based on Wikipedia's comprehensive "Signs of AI writing" guide. Detects and fixes patterns including: inflated symbolism, promotional language, superficial -ing analyses, vague attributions, em dash overuse, rule of three, AI vocabulary words, negative parallelisms, and excessive conjunctive phrases.
find-skills
Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.
tavily-search
Use Tavily API for real-time web search and content extraction. Use when: user needs real-time web search results, research, or current information from the web. Requires Tavily API key.
baidu-search
Search the web using Baidu AI Search Engine (BDSE). Use for live information, documentation, or research topics.
agent-autonomy-kit
Stop waiting for prompts. Keep working.
Meeting Prep
Never walk into a meeting unprepared again. Your agent researches all attendees before calendar events—pulling LinkedIn profiles, recent company news, mutual connections, and conversation starters. Generates a briefing doc with talking points, icebreakers, and context so you show up informed and confident. Triggered automatically before meetings or on-demand. Configure research depth, advance timing, and output format. Walking into meetings blind is amateur hour—missed connections, generic small talk, zero leverage. Use when setting up meeting intelligence, researching specific attendees, generating pre-meeting briefs, or automating your prep workflow.
self-improvement
Captures learnings, errors, and corrections to enable continuous improvement. Use when: (1) A command or operation fails unexpectedly, (2) User corrects Claude ('No, that's wrong...', 'Actually...'), (3) User requests a capability that doesn't exist, (4) An external API or tool fails, (5) Claude realizes its knowledge is outdated or incorrect, (6) A better approach is discovered for a recurring task. Also review learnings before major tasks.
