GitHub Copilot CLI Agent & Sessions View for JetBrains v2026.5

TL;DR

  • Copilot CLI agent now runs directly in JetBrains IDEs with worktree and workspace isolation modes
  • Unified sessions view tracks all agent runs in one place with live status and filtering
  • Ask question tool lets agents request clarification mid-task; global .agent.md support for custom agents across workspaces
  • Edit mode removed; plan agent no longer auto-invoked in sub-agent workflows

New

  • Copilot CLI agent in JetBrains — Delegate terminal-based tasks from the IDE with editor context already connected. Choose worktree isolation (separate Git branch, safe review before merge) or workspace isolation (direct changes, faster iteration).
  • Unified sessions view — Track all agent sessions in chat with title, type, elapsed time, and status. Filter by agent type or status to find sessions fast.
  • Ask question tool in agent mode — Agents can now ask clarifying questions when they need more info, reducing ambiguity and improving accuracy. Works across agent mode, custom agents, sub-agents, and Copilot CLI agent.
  • Global .agent.md support — Define custom agents at ~/.copilot/agents and use them across all workspaces. In-product UI for managing global agents coming soon.
  • GitHub Enterprise Server (GHES) sign-in — Select "Continue with GitHub Enterprise" during sign-in to authenticate with your enterprise instance by hostname or URL.

Fixed

  • Code completions now work on secondary screens
  • Shift+Home and Shift+End inline selection issues resolved
  • Drag-and-drop file addition to Copilot Chat improved
  • UI responsiveness improved; occasional freezes reduced
  • Sub-agent rendering and styling for current file context improved
  • Code review apply behavior improved for full-line replacements

Breaking Changes

  • Edit mode support removed — use agent or ask mode instead
  • Plan agent no longer auto-invoked in sub-agent workflows — select it manually from the mode picker if needed
