VS Code Multi-Agent Development: Claude and Codex in Agent Sessions (Feb 2026)

Summary

VS Code's early 2026 release (1.109) introduced multi-agent support: developers can run Claude and Codex agents locally or in the cloud alongside GitHub Copilot in a unified Agent Sessions view. This reflects the shift from single-model assistants to coordinated multi-agent development environments and aligns with the trend toward agentic coding workflows in mainstream IDEs.
