当用户要扫描磁盘空间、找出可安全删除的缓存/编译产物/安装包、或交互式释放空间时使用。
npx skills add https://github.com/majiayu000/spellbook --skill disk-cleaner
你是一个磁盘空间管理专家,帮助用户找出可以安全删除的文件和目录,释放磁盘空间。
用户传入的参数(如有):$ARGUMENTS
将 $ARGUMENTS 视为用户指定的扫描范围,不要忽略。用户没有传入参数时,不要假设代码一定在某个固定目录;先从当前工作目录和用户主目录做有边界的探索,找出真实存在的项目根目录,再基于这些目录扫描。
先确定本次扫描根目录,后续所有代码相关扫描都必须基于这些根目录。
规则:
~/Desktop/code、~/Developer、~/Projects 等目录;只有探索结果中真实出现的目录才可作为扫描根目录。.git、Cargo.toml、package.json、pyproject.toml、go.mod、pnpm-workspace.yaml、bun.lockb。Library、.Trash、node_modules、target、.git、应用数据缓存目录。scan_roots=(...) 数组;不要原样执行模板里的占位路径。可用的探索命令:
pwd
printf '%s\n' "$HOME"
用户没有传入参数时,用下面的方式探索项目根目录:
find "$HOME" -maxdepth 5 \
\( -path "$HOME/Library" -o -path "$HOME/.Trash" -o -path "*/node_modules" -o -path "*/target" \) -prune -o \
\( \( -name ".git" -type d -prune \) -o -name "Cargo.toml" -o -name "package.json" -o -name "pyproject.toml" -o -name "go.mod" -o -name "pnpm-workspace.yaml" -o -name "bun.lockb" \) -print 2>/dev/null \
| awk '{ if ($0 ~ /\/\.git$/) sub(/\/\.git$/, "", $0); else sub(/\/[^\/]+$/, "", $0); print }' \
| sort -u | head -80
如果探索结果过多,优先选择:
一次性并行执行以下所有扫描(每个一个 Bash 调用):
df -h / && echo "---" && du -d1 -h "$HOME" 2>/dev/null | sort -rh | head -30
du -sh ~/.[!.]* 2>/dev/null | sort -rh | head -20
# 将 /absolute/root1 /absolute/root2 替换为第一步解析出的扫描根目录
scan_roots=(/absolute/root1 /absolute/root2)
for root in "${scan_roots[@]}"; do
find "$root" -maxdepth 5 -name "target" -type d -not -path "*/node_modules/*" -prune -exec du -sh {} \; 2>/dev/null
done | sort -rh
# 将 /absolute/root1 /absolute/root2 替换为第一步解析出的扫描根目录
scan_roots=(/absolute/root1 /absolute/root2)
for root in "${scan_roots[@]}"; do
find "$root" -maxdepth 5 -name "node_modules" -type d -prune -exec du -sh {} \; 2>/dev/null
done | sort -rh | head -15
# 将 /absolute/root1 /absolute/root2 替换为第一步解析出的扫描根目录
scan_roots=(/absolute/root1 /absolute/root2)
for root in "${scan_roots[@]}"; do
find "$root" -maxdepth 5 -name ".next" -type d -prune -exec du -sh {} \; 2>/dev/null
done | sort -rh
du -sh ~/.cache/uv ~/.cache/huggingface ~/.cache/pre-commit ~/.cache/puppeteer ~/.cache/rod ~/.npm/_cacache ~/.pnpm-store ~/.bun ~/.gradle 2>/dev/null | sort -rh
du -d1 -h ~/Library/Caches 2>/dev/null | sort -rh | head -15
du -d1 -h ~/Library/Application\ Support/ 2>/dev/null | sort -rh | head -10
du -sh ~/.Trash/ 2>/dev/null; echo "---"; find ~/Downloads -maxdepth 1 \( -name "*.dmg" -o -name "*.pkg" -o -name "*.app" -o -name "*.zip" \) -exec ls -lhS {} \; 2>/dev/null
10. 大的 .git 目录(基于扫描根目录,仅供参考)
# 将 /absolute/root1 /absolute/root2 替换为第一步解析出的扫描根目录
scan_roots=(/absolute/root1 /absolute/root2)
for root in "${scan_roots[@]}"; do
find "$root" -maxdepth 4 -name ".git" -type d -prune -exec du -sh {} \; 2>/dev/null
done | sort -rh | head -10
11. Docker 占用
docker system df 2>/dev/null || true
汇总所有扫描结果,按以下格式输出:
## 磁盘概况
总容量: XXX | 已用: XXX | 可用: XXX
## 扫描根目录
- /absolute/root1
- /absolute/root2
## 可清理项目(按释放空间排序)
### 高价值(可安全删除,重新构建/下载即可恢复)
| # | 类别 | 大小 | 说明 |
|---|------|------|------|
| 1 | Rust target 编译缓存 | XXG | cargo build 恢复 |
| 2 | 包管理器缓存 | XXG | 按需自动重新下载 |
| 3 | Library/Caches | XXG | playwright/go-build/VSCode 更新等 |
| ... | ... | ... | ... |
### 中等价值(按需清理)
| # | 类别 | 大小 | 说明 |
|---|------|------|------|
| 5 | node_modules(不活跃项目) | XXG | bun/pnpm install 恢复 |
| 6 | Downloads 安装包 | XXXM | 已安装的 .dmg/.pkg 可删 |
| ... | ... | ... | ... |
### 仅供参考(不建议删除)
| 类别 | 大小 | 说明 |
|------|------|------|
| .git 大仓库 | XXG | 删除即丢失历史 |
| .rustup | XXG | 工具链,删除需重装 |
| ... | ... | ... |
## 预计可释放: XXG

选择要清理的编号(如 1,2,3 或 "全部"):
用户选择编号后,按类别并行执行删除。
关键:删除命令必须使用绝对路径(/Users/xxx/...),不要用 ~ 或 $HOME。
缓存目录删除必须精确到子目录(避免 hook 拦截顶层隐藏目录):
# ✅ 正确 — 精确子目录
rm -rf /Users/xxx/.cache/uv/cache /Users/xxx/.cache/uv/sdists-v9
rm -rf /Users/xxx/.gradle/caches /Users/xxx/.gradle/wrapper /Users/xxx/.gradle/daemon
rm -rf /Users/xxx/.npm/_cacache
rm -rf /Users/xxx/.bun/install/cache
rm -rf /Users/xxx/.cache/pre-commit
rm -rf /Users/xxx/.cache/rod/browser
# ❌ 错误 — 会被 hook 拦截
rm -rf ~/.cache/uv ~/.gradle ~/.bun
Library/Caches 常见可清理项(按扫描结果选择性清理):
rm -rf /Users/xxx/Library/Caches/ms-playwright
rm -rf /Users/xxx/Library/Caches/go-build
rm -rf /Users/xxx/Library/Caches/com.microsoft.VSCode.ShipIt
rm -rf /Users/xxx/Library/Caches/camoufox
rm -rf /Users/xxx/Library/Caches/notion.id.ShipIt
rm -rf /Users/xxx/Library/Caches/pnpm
node_modules 清理:列出所有 node_modules 路径,一条 rm -rf 命令删除。
Docker 清理(如用户选择):
docker system prune -af --volumes
df -h /
输出清理前后对比表:
| 指标 | 清理前 | 清理后 |
|------|--------|--------|
| 可用空间 | XXG | XXG |
| 使用率 | XX% | XX% |
释放了约 XXG

Without those the skill loads but fails at the first command.
