Copilot usage metrics now aggregate Copilot cloud agent active user counts

GitHub has updated the Copilot usage metrics API to include aggregated active user counts for the Copilot cloud agent (formerly Copilot coding agent). Three new fields are now available in both 1-day and 28-day reports at enterprise and organization levels: daily, weekly, and monthly active Copilot cloud agent user counts. These nullable fields complement existing metrics like IDE agent mode counts, giving admins a complete view of Copilot adoption across surfaces without needing to aggregate user-level data manually.
