What it does

Busybox On Windows is an agent skill from davila7/claude-code-templates. How to use a Win32 build of BusyBox to run many of the standard UNIX command line tools on Windows.

Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Windows and PowerShell. The repository describes itself as: CLI tool for configuring and monitoring Claude Code. The licence is MIT.

Example prompts

  • “/busybox-on-windows”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Print the type of CPU: Get-CimInstance -ClassName Win32_Processor | Select-Object Name, NumberOfCores, MaxClockSpeed
  2. Print the OS versions: Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" | Select-Object ProductName, DisplayVersion…
  3. Download a suitable build of BusyBox by running one of these PowerShell commands

What it can do on your machine

Read from SKILL.md and the folder at commit c0ca7da. 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

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • frippery.org

    Also links to:

    • busybox.net

    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

Busybox On Windows loads about 480 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 189 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~480

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); files beside SKILL.md are not scanned.

How to use a Win32 build of BusyBox to run many of the standard UNIX command line tools on Windows.
license
MIT

BusyBox is a single binary that implements many common Unix tools.

Use this skill only on Windows. If you are on UNIX, then stop here.

Run the following steps only if you cannot find a busybox.exe file in the same directory as this document is. These are PowerShell commands, if you have a classic cmd.exe terminal, then you must use powershell -Command "..." to run them.

  1. Print the type of CPU: Get-CimInstance -ClassName Win32_Processor | Select-Object Name, NumberOfCores, MaxClockSpeed
  2. Print the OS versions: Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" | Select-Object ProductName, DisplayVersion, CurrentBuild
  3. Download a suitable build of BusyBox by running one of these PowerShell commands:
    • 32-bit x86 (ANSI): $ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox.exe -OutFile busybox.exe
    • 64-bit x86 (ANSI): $ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64.exe -OutFile busybox.exe
    • 64-bit x86 (Unicode): $ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64u.exe -OutFile busybox.exe
    • 64-bit ARM (Unicode): $ProgressPreference = 'SilentlyContinue'; Invoke-WebRequest -Uri https://frippery.org/files/busybox/busybox64a.exe -OutFile busybox.exe

Useful commands:

  • Help: busybox.exe --list
  • Available UNIX commands: busybox.exe --list

Usage: Prefix the UNIX command with busybox.exe, for example: busybox.exe ls -1

If you need to run a UNIX command under another CWD, then use the absolute path to busybox.exe.
