设计并创建一个子智能体，或改进一个已有的子智能体。当用户说"帮我建一个负责 X 的智能体"、"我想要个专门做 Y 的助手"、"把这套活儿交给一个专门的智能体"、"改一下我那个智能体的职责/能力/语气"、或问"这个智能体该怎么设计"时，务必使用本技能。它教你怎么切职责、怎么写 system_prompt、绑哪些能力、参数怎么定，然后通过 create_agent / edit_agent 工具落库。
从零攒一个插件包，或把一个 web 链接上的插件下载下来导入。当用户说"照着这个网页做个插件"、"把我这几个技能打包成插件"、"帮我做一个插件"、"这个链接的插件帮我装上"、或需要把一组配套的技能与工具打成可安装可卸载的整体时，务必使用本技能。它教你插件包的目录结构、plugin.json 怎么写、怎么自检、怎么通过 import_plugin 工具落库。
HugAgentOS 后端开发规范。当需要新增或修改后端代码（API路由、服务层、数据库模型、MCP工具等）时使用此 skill， 确保代码风格、分层架构、错误处理、响应格式等与项目现有规范保持一致。

Systematic debugging methodology and language-specific debugging commands.
git bisect.# Node.js debugger
node --inspect-brk app.js
# Chrome DevTools: chrome://inspect
# Console debugging
console.log(JSON.stringify(obj, null, 2))
console.trace('Call stack here')
console.time('perf'); /* code */ console.timeEnd('perf')
# Memory leaks
node --expose-gc --max-old-space-size=4096 app.js
# Built-in debugger
python -m pdb script.py
# Breakpoint in code
breakpoint() # Python 3.7+
# Verbose tracing
python -X tracemalloc script.py
# Profile
python -m cProfile -s cumulative script.py
# LLDB debugging
lldb ./MyApp
(lldb) breakpoint set --name main
(lldb) run
(lldb) po myVariable
# Xcode: Product → Profile (Instruments)
/* Outline all elements */
* { outline: 1px solid red !important; }
/* Debug specific element */
.debug { background: rgba(255,0,0,0.1) !important; }
# HTTP debugging
curl -v https://api.example.com/endpoint
curl -w "@curl-format.txt" -o /dev/null -s https://example.com
# DNS
dig example.com
nslookup example.com
# Ports
lsof -i :3000
netstat -tlnp
git bisect start
git bisect bad # Current commit is broken
git bisect good abc1234 # Known good commit
# Git checks out middle commit — test it, then:
git bisect good # or git bisect bad
# Repeat until root cause commit is found
git bisect reset
| Error | Likely Cause | Fix |
|---|---|---|
Cannot read property of undefined | Missing null check or wrong data shape | Add optional chaining (?.) or validate data |
ENOENT | File/directory doesn't exist | Check path, create directory, use existsSync |
CORS error | Backend missing CORS headers | Add CORS middleware with correct origins |
Module not found | Missing dependency or wrong import path | npm install, check tsconfig paths |
Hydration mismatch (React) | Server/client render different HTML | Ensure consistent rendering, use useEffect for client-only |
Segmentation fault | Memory corruption, null pointer | Check array bounds, pointer validity |
Connection refused | Service not running on expected port | Check if service is up, verify port/host |
Permission denied | File/network permission issue | Check chmod, firewall, sudo |
# What's using this port?
lsof -i :PORT
# What's this process doing?
ps aux | grep PROCESS
# Watch file changes
fswatch -r ./src
