How to use the Windows Batch File Expert agent skill
Updated · written with AI from the project's own documentation and checked against our catalogue data
The batch-files skill is a set of instructions and templates that teaches an AI agent the detailed rules of Windows cmd.exe batch scripting. Once it is installed, the agent writes, fixes and explains .bat and .cmd files with those rules in mind. This guide covers what the skill does, how to install it, how to ask for help with natural requests, and what to check before running the scripts it produces.
Windows Batch File Expertgithub/awesome-copilot · MIT Download the skill Quick start
- 1Download the ZIP. Download the batch-files ZIP from this page.
- 2Unzip into a skills folder. Unzip it into ~/.claude/skills/ for all projects, or into a project's .claude/skills/ folder for one project only.
- 3Or upload it in the Claude apps. Go to Settings → Capabilities → Skills and upload the skill there.
- 4Describe your task. Ask in plain language, for example to create a batch file that backs up a folder.
- 5Review the output. Read the generated .bat or .cmd file and check any delete, move or overwrite commands.
- 6Test safely. Run the script on sample data or a copy first, then on the real target once you are satisfied.
What the batch-files skill makes the agent do
The skill covers cmd.exe syntax, environment variables, control flow, string processing, error handling and integration with system tools. It applies when you ask for a batch file, a scheduled task script, a small command-line tool for a bin folder on PATH, or help with an existing .bat or .cmd file in your workspace.
The skill is mostly reference knowledge and templates. It does not run anything on your machine, and it does not use the network.
- Writes new .bat or .cmd scripts for file operations, deployments and backups
- Debugs issues such as variable expansion, error levels and quoting
- Uses templates for standalone command-line tools, reusable function libraries and automation tasks
- Avoids common mistakes such as spaces around '=' or confusing parse-time and runtime variable expansion
Install the batch-files skill
Download the batch-files ZIP from this page. Then choose one of the following options.
For a personal skill available in all projects, unzip it into ~/.claude/skills/. For a skill that applies only to one project, unzip it into that project's .claude/skills/ folder.
In the Claude apps, you can instead upload the skill under Settings → Capabilities → Skills.
- Personal: ~/.claude/skills/
- Project only: .claude/skills/ inside your project folder
- Claude apps: Settings → Capabilities → Skills
Trigger the skill with natural requests
You do not need a special command. Describe the task in plain language and mention Windows or a batch file. The skill is designed to respond to requests such as creating a batch file, writing a .bat script, automating a Windows task, CMD scripting, or building a scheduled task script.
If you are working in a folder that contains .bat or .cmd files, you can also ask for help with those files directly.
- "Create a batch file that copies my Documents folder to D:\Backup each night."
- "Write a .bat script that renames all .log files in a folder by date."
- "Debug this batch file; the variable is empty inside my for loop."
- "Make a scheduled task script that cleans up files in %TEMP% older than 7 days."
Understand what the skill includes
The skill ships with templates for three kinds of script: a standalone command-line tool (assets/executable.txt), a reusable function library with CALL-able labels (assets/library.txt), and an automation task with a dry-run option (assets/task.txt). Reference notes cover tools and resources, and how the Windows environment relates to Cygwin, MSYS2 and Windows Subsystem for Linux.
The templates include help blocks and find-and-replace instructions, so the agent can produce a script with usage text already in place.
- assets/executable.txt: command-line tool with argument parsing and help options
- assets/library.txt: reusable functions such as trimWhitespace, toLower, getTimestamp, logMessage and padRight
- assets/task.txt: scheduled or manual task with a --dry preview option
- references/: notes on Cygwin, MSYS2, Windows Subsystem for Linux and tools and resources
Check and run the scripts safely
Agent-written batch code can still contain bugs or destructive commands. Read the script before you run it, especially anything that deletes, moves or overwrites files. Test on a copy of your data first.
For production scripts or important systems, have the code reviewed before running it. The skill does not run scripts for you, so the testing step is yours.
- Read every delete, move and overwrite command before running it
- Test on sample files or a copy of the target folder
- Use the --dry option in the task template where it fits, to preview actions
- Get a second review for scripts that touch important systems
What people use it for
- Windows administrators writing file backup or deployment scripts
- Scheduled task scripts that run maintenance or cleanup jobs
- Small command-line tools placed in a bin folder on PATH
- Fixing a batch file where variables are empty or quoting breaks
- Learning why a batch script behaves unexpectedly
Frequently asked questions
Is the batch-files skill free?
The skill is published under the MIT licence in the github/awesome-copilot repository. The source does not list prices, so check the repository for the licence terms that apply to your use.
What do I need to use the batch-files skill?
The source lists no required tools or packages. The skill targets Windows NT-based systems, Windows 7 or later, which have cmd.exe built in.
Does the batch-files skill run scripts on my computer?
No. The skill is mostly reference knowledge and templates. It does not run scripts and does not use the network.
Where do I install the batch-files skill?
Unzip the downloaded ZIP into ~/.claude/skills/ for personal use, or into a project's .claude/skills/ folder for one project. In the Claude apps, upload it under Settings → Capabilities → Skills.
Can I use this skill for bash or PowerShell scripts?
No, it is built for Windows batch files and cmd.exe. For cross-platform automation on macOS or Linux, the source says bash or PowerShell is a better fit.
Why does my batch file variable come out empty inside a loop?
Variables inside parenthesized blocks are expanded at parse time with %VAR%. The skill describes delayed expansion with setlocal EnableDelayedExpansion and !VAR!, which reads the value at execution time.

Our verdict
Use the batch-files skill if you write or maintain Windows .bat and .cmd scripts and want an agent that knows cmd.exe's quirks. Pick something else for macOS or Linux automation, or if you need a tool that runs and tests scripts for you. Always read agent-written batch code before running it on important data.
