Copilot Code Review Metrics Now Break Down by Comment Type

TL;DR

• Copilot usage metrics API now reports code review suggestions grouped by comment type (security, bug_risk, etc.)
• See which suggestion types developers actually apply vs. ignore
• Available at enterprise and organization levels; repository-level drill-down coming later

New

• Comment type breakdown in usage metrics — The copilot_suggestions_by_comment_type array now appears under pull_requests in both enterprise and organization reports, showing aggregated counts by category.
• Applied suggestions tracking — Each comment type now reports both total suggestions posted and how many were actually applied by developers, letting you measure which feedback sticks.
• Single-day and 28-day rolling windows — Metrics available at both granularities for enterprise and organization scopes.

What You Get

• comment_type — The category Copilot assigned (e.g., security, bug_risk).
• total_copilot_suggestions — Count of suggestions of that type posted during the period.
• total_copilot_applied_suggestions — How many were applied by developers.

Important Notes

• Enterprise admins and organization owners with Copilot usage metrics access can query this via REST API.
• Only suggestions posted by Copilot code review are included; metrics reflect the comment type assigned at post time.
• Repository-level drill-down is not yet available but is being investigated.

Update your API calls to the Copilot usage metrics API to start pulling comment type data.
