GitHub Copilot agent mode reaches GA on JetBrains — multi-IDE agentic coding now baseline

GitHub Copilot's agent mode is now generally available on JetBrains in addition to VS Code, completing the multi-IDE rollout that started in late 2025. Combined with the March 2026 agentic code review release, Copilot now spans context-gathering, autonomous PR drafting, and review-stage gating across the two largest IDE ecosystems.

The structural implication: agentic coding workflows are no longer a Cursor-or-Copilot bet. JetBrains-shop enterprises (predominantly Java/Kotlin/Scala) had been the last meaningful holdout from the autonomous-agent transition. With Copilot agent mode GA on IntelliJ, that gap closes.

Watch the next-quarter merge-rate metric. Engineering leadership now has the tooling to pilot agent-merge automation on the routine-tier workloads across both ecosystems. The orgs that move first capture the throughput delta; the orgs that wait spend Q3 explaining the productivity gap.
