How to export Xcode agent skills with xcrun

Xcode 27 includes agent skills that help coding agents follow SwiftUI best practices and adopt new APIs.

You can export these skills and use them outside Xcode with a single command:

xcrun agent skills export

Apple demonstrates this in What's new in SwiftUI at WWDC26. The export produces Markdown files that you can bring into your own coding workflow.

Export skills to a specific folder

To choose where the exported skills go, use the --output-dir option:

xcrun agent skills export --output-dir ~/Downloads/xcode-skills

This writes the skill subdirectories into xcode-skills in your Downloads folder. Open that folder to inspect the exported instructions before adding them to your agent.

If you export again and want to overwrite existing skill directories, add --replace-existing:

xcrun agent skills export \
  --output-dir ~/Downloads/xcode-skills \
  --replace-existing

You can check the options available in your installed Xcode with:

xcrun agent skills export --help

If xcrun cannot find the agent command

Check which Xcode your command line tools are using:

xcode-select -p

If you have multiple versions installed, make sure the selected developer directory belongs to Xcode 27. You can change this in Xcode > Settings > Locations > Command Line Tools.

You can also choose an Xcode installation for just one command with DEVELOPER_DIR:

DEVELOPER_DIR="/Applications/Xcode-beta.app/Contents/Developer" \
  xcrun agent skills export --output-dir ~/Downloads/xcode-skills

Replace Xcode-beta.app with the name of your Xcode 27 installation.
