GitHub has expanded the Copilot usage metrics API to track the activity of individual third-party agents

GitHub has expanded the Copilot usage metrics API with a new optional field, totals_by_3rd_party_agent. The field contains one entry for each recognized agent app and is available in 1-day and 28-day reports at the enterprise, organization, enterprise-user and organization-user levels. Each entry contains agent_name (a display name that may change, which is why GitHub recommends grouping by agent_id), user_initiated_interaction_count (the number of times a user launches the agent) and session_count (the number of sessions) – session_count is available only in aggregate enterprise and organization reports and is absent from per-user records.

According to GitHub, agent activity was previously tracked in the metrics as a single aggregate indicator, making it impossible to distinguish work by Copilot coding agent from the activity of other agents, such as Claude or Codex, running through GitHub workflows. According to the company, breaking down activity by individual agent is intended to allow each agent app to be tracked separately, their adoption to be compared, and rollout and licensing decisions to be based on actual usage rather than estimates.

Access to the data requires the View Copilot Metrics permission and the Copilot usage metrics policy to be enabled. If no activity from a recognized agent app is recorded during the given period, the totals_by_3rd_party_agent field does not appear in the report at all.
