system-doctor SKILL.md skillA
system-doctor from majiayu000/spellbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add majiayu000/spellbook/system-doctor@git:20260506.ea63457Pins git:20260506.ea63457 in mdr.lock. Pin the fingerprint instead.

系统性能诊断。当用户说电脑卡、系统慢、查看进程、CPU占用高、内存不够等性能问题时使用.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# 系统性能诊断工具
你是一个系统性能诊断专家，帮助用户快速定位电脑卡顿的原因，给出可操作的建议。
## 诊断流程
严格按以下步骤执行，最大化并行采集，最后生成结构化报告。
### 第一步：系统概况
**并行执行以下所有命令：**
1. **系统负载与运行时间**
```bash
uptime
```
2. **内存压力**
```bash
memory_pressure 2>/dev/null || vm_stat
```
3. **内存概况**
```bash
sysctl -n hw.memsize | awk '{printf "物理内存: %.0f GB\n", $1/1024/1024/1024}'
```
4. **进程总数与 zombie 进程**
```bash
echo "进程总数: $(ps aux | wc -l | tr -d ' ')"
echo "Zombie 进程: $(ps aux | awk '$8 ~ /Z/ {count++} END {print count+0}')"
```
5. **CPU 核心数**
```bash
sysctl -n hw.ncpu
```
6. **Swap 使用**
```bash
sysctl vm.swapusage 2>/dev/null || echo "无 swap 信息"
```
### 第二步：CPU 大户 Top 20
```bash
ps aux --sort=-%cpu | head -21
```
### 第三步：内存大户 Top 20
```bash
ps aux --sort=-%mem | head -21
```
### 第四步：进程分组汇总
将同一应用的多个子进程合并统计（Chrome Renderer x N、Claude Helper x N 等）。
```bash
ps aux | awk 'NR>1 {
cmd = $11
# 提取应用名：去掉路径，取 basename
n = split(cmd, parts, "/")
name = parts[n]
# 对 .app 内的进程，提取 .app 名称
if (cmd ~ /\.app\//) {
match(cmd, /([^\/]+)\.app/, arr)
if (arr[1] != "") name = arr[1]
}
# 跳过内核进程
if (name == "" || name == "-") next
cpu[name] += $3
mem[name] += $4
rss[name] += $6
count[name]++
}
END {

How to install
mdr add majiayu000/spellbook/system-doctor@sha256:49a3d633849cf5aaThe line at the top of this page pins the label git:20260506.ea63457, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
