Custom agents available in GitHub Copilot for JetBrains, Eclipse, and Xcode now in public preview

Custom agents are now in public preview for JetBrains IDEs, Eclipse, and Xcode, allowing you to package reusable expertise, guardrails, and tool access into AI agents tailored to your project or organization.

What’s new

Custom agents bring customization to your chat mode by letting you specify name, description, tools, and models.
