Pre-requisites

• VS code insiders
• Following settings enabled

  "chat.editor.codex.preferAgentHost": true, 
  "chat.agentHost.codexAgent.enabled": true,
  "chat.agentHost.claudeAgent.enabled": true
  "chat.agentHost.copilotAgent.multiRootEnabled": true,
  "chat.agentHost.claudeAgent.multiRootEnabled": true,
  "chat.agentHost.codexAgent.multiRootEnabled": true,

• Setup of Multi-root workspaces https://code.visualstudio.com/docs/editing/workspaces/multi-root-workspaces
• Do not use Agents Window (its not supported)
• Focus on Claude and Codex, testing with Copilot is a separate TPI, but feel free to test that as well

Steps:

• Use hooks, custom agents, instructions, skills, mcp servers (vscode mcp servers, .mcp.json) from across multiple workspaces
• Test editing, creating PRs and the like across multiple repos when using multi-root workspace folders in VS Code
• Verify everything works as expected in Copilot Agent with Mult-root workspaces
• Note: Please test Codex and Claude Agents (both)

Note:

• When filing an issue, please ensure you share the agent host session logs (using command Export Agent Host Debug Logs)
