What it does
C Drive Cleaner is an agent skill from staruhub/ClaudeSkills. Windows C盘清理和磁盘空间管理。当用户说C盘满了、磁盘空间不足、清理临时文件/缓存/回收站/系统日志、查找大文件、分析磁盘占用时使用。仅适用于 Windows 环境。不用于：macOS/Linux 磁盘清理、卸载软件（引导用户走系统卸载）、清理用户个人文件（只报告位置，删除决定权在用户）。
Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `references/windows_cleanup_guide.md`, `scripts/analyze_disk.py` and `scripts/clean_temp.py`).
It works with Linux and macOS. The repository describes itself as: 13 curated Agent Skills for research, product decisions, decks, publishing, audits, and more — portable across skills-compatible agents. The licence is MIT.

Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 66e02d2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 3 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
C Drive Cleaner loads about 518 tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 95 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

C盘清理大师
安全导向的 Windows 磁盘清理：分析 → 模拟 → 执行 → 验证，破坏性操作永远先预览。
验收标准（清理任务完成前自查）
- 实际删除前完成过一次模拟运行，并把预览结果给用户看过
-
--execute前用户明确确认过（清理不经过回收站，不可恢复） - 已提醒用户创建系统还原点和关闭浏览器（清缓存时）
- 未触碰"禁删清单"中的任何目录
- 清理后重跑分析,回报实际释放的空间数字,不是"应该清理了"
- 用户个人大文件（视频/压缩包等）只报告位置与大小，删除由用户自己决定
禁删清单（碰到即停）
C:\Windows\System32— 核心系统文件C:\Windows\WinSxS— Windows 组件存储（要瘦身走 DISM，不许直接删）C:\Program Files/C:\ProgramData— 已装程序及数据C:\Windows\Prefetch— 预读取文件，删了拖慢启动- 休眠文件与虚拟内存 — 走系统设置调整，不手动删文件
工作流程
1. 分析占用
python scripts/analyze_disk.py C:\ 2 20 # 路径 深度 显示前N项2. 查找大文件（只报告，不删）
python scripts/find_large_files.py C:\ 100 50 # 路径 最小MB 最大结果数
python scripts/find_large_files.py C:\Users 200 100 .mp4,.avi,.mkv # 按类型过滤常见大文件类型：视频 .mp4,.mkv,.mov；安装包 .iso,.exe,.msi；压缩包 .zip,.rar,.7z；备份 .bak,.sql。
3. 清理（默认模拟模式）
python scripts/clean_temp.py # 模拟：只预览
python scripts/clean_temp.py --execute # 实际执行：需二次确认覆盖范围：%TEMP%、C:\Windows\Temp、浏览器缓存（Chrome/Edge/Firefox）、.log/.etl/.old 日志、回收站。
4. 验证
重跑 analyze_disk.py，对比前后数字回报实际效果。
已知陷阱
| 陷阱 | 具体表现 | 应对 |
|---|---|---|
| 无权限静默漏扫 | 非管理员运行，扫描结果偏小误导判断 | 提示以管理员身份运行；脚本会跳过无权目录并计数 |
| 浏览器缓存清理失败 | 浏览器进程占用文件 | 先关闭所有浏览器窗口再清 |
| 清完没效果 | 临时文件本来就不大，大头是个人文件或程序 | 回到大文件报告和目录排行,引导用户决策(卸载/转移) |
| 误以为可恢复 | 脚本删除不经回收站 | 执行前明确告知不可恢复,这也是模拟先行的原因 |
| SSD 清到贴满 | 追求 100% 利用率 | SSD 保留 15-20% 空间维持性能;低于 20% 时才建议清理 |
权限与配套
- 部分系统文件需管理员权限（右键"以管理员身份运行"）
- 可配合系统自带工具：
cleanmgr、存储感知、DISM 组件清理 - 深入的垃圾文件位置、清理命令、安全实践：
references/windows_cleanup_guide.md
脚本说明
| 脚本 | 功能 | 安全特性 |
|---|---|---|
scripts/analyze_disk.py | 目录占用排行 + 大文件列表 | 只读；自动跳过无权目录 |
scripts/find_large_files.py | 按大小/类型查找文件 | 只读；显示访问时间辅助判断 |
scripts/clean_temp.py | 清理临时文件/缓存/日志/回收站 | 默认模拟；--execute 二次确认；跳过系统关键目录 |

Can I use C Drive Cleaner in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add staruhub/ClaudeSkills --skill c-drive-cleaner -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/c-drive-cleaner, .gemini/skills/c-drive-cleaner, .github/skills/c-drive-cleaner and .opencode/skills/c-drive-cleaner in your project.
What does C Drive Cleaner need to run?
Going by SKILL.md and its folder, C Drive Cleaner needs Python for the scripts in its folder and the command-line tools its instructions call (python). Our summary lists: Python 3.
Does C Drive Cleaner access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is C Drive Cleaner safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does C Drive Cleaner use?
C Drive Cleaner is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does C Drive Cleaner use?
About 518 tokens (SKILL.md is roughly 2.1k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.5k tokens, read only when the agent opens those files.
What are the alternatives to C Drive Cleaner?
Skills that share tags, products or a category with C Drive Cleaner: Engine Whats New (flutter/flutter, 180k stars), Openclaw Live Updater (openclaw/openclaw, 392k stars), Apple Container Test Runner (RustPython/RustPython, 22k stars) and Native Feel Cross Platform Desktop (yetone/native-feel-skill, 1.9k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
