+
+You can allow your {% data variables.product.prodname_copilot_extension_short %} to receive context from the editor, such as the currently opened file, by enabling the **Read-only** access level for the "{% data variables.product.prodname_copilot_short %} Editor Context" permission in your {% data variables.product.prodname_github_app %} settings. See "[AUTOTITLE](/copilot/building-copilot-extensions/creating-a-copilot-extension/creating-a-github-app-for-your-copilot-extension#creating-a-github-app)."
+
+The {% data variables.product.prodname_copilot_extensibility_platform %} automatically handles messaging when implicit and explicit context is unavailable or unauthorized. To enable context passing, you are required to request permissions from users. When requesting permissions, follow these best practices:
+
+* Clearly communicate what context you need and what you need it for.
+* Implement appropriate error handling for unavailable context that your own application logic and API calls.
+* In the event context is unavailable, provide value where possible without this data.
+* Request only the minimum required permissions for your extension.
+
+Context passing respects content exclusions, `.env` files, and files listed in the content exclusion settings.

+## About context passing in {% data variables.product.prodname_copilot_extensions %}
+
+{% data reusables.copilot.copilot-extensions.context-passing-public-preview-note %}
+
+{% data variables.product.prodname_copilot_extensions %} can access certain contextual information depending on where you're using them. This context passing happens automatically when you interact with an extension, but requires your explicit authorization through {% data variables.product.prodname_github_app %} permissions for use in any organization-owned repositories.
+
+Context passing helps extensions understand your current work environment to provide more relevant assistance, while maintaining security through permission controls. Context passing also respects content exclusions, `.env` files, and files listed in your content exclusion settings.
+
+The following table shows the contexts that are passed to {% data variables.product.prodname_copilot_extensions %} based on the client or IDE you are using.
