GitHub Copilot suggests custom properties definitions

GitHub launched a public preview feature that lets GitHub Copilot suggest allowed values when enterprise and organization admins create custom property definitions for repositories, available on GitHub Copilot Business and Copilot Enterprise plans. The suggestions are generated from the property being defined — for example, a multi-select property named FedRAMP surfaces compliance-related values, while a single-select property like internet-facing surfaces values such as yes and no — and can be accepted in one click. Enterprise and organization owners can control availability through the Repository custom property suggestions Copilot policy.

GitHub Copilot can now suggest allowed values when you create a custom property for repositories in your organization. This feature is in public preview for GitHub Copilot Business and Copilot Enterprise plans.

Custom properties let enterprise and organization admins attach governance metadata to repositories, which you can then use to target repositories with rulesets. Custom properties are one of the most popular ways to scope rulesets, but getting started has been a challenge. Admins often aren’t sure which properties to define or what allowed values to use, and inconsistent metadata makes it harder to apply governance consistently across a large fleet of repositories.

With this release, when you create a new custom property definition at the enterprise or organization level, Copilot will suggest relevant allowed values based on the property you’re defining. For example:

  • Creating a multi-select property like FedRAMP surfaces suggested compliance-related values.
  • Creating a single-select property like internet-facing surfaces suggested values such asyes andno .

You can accept a suggestion in one click, helping you stand up a meaningful custom property taxonomy faster.

Enterprise and organization owners can now configure the Repository custom property suggestions Copilot policy to control feature availability.
