Setup:

• Open Agents app
• Configure the following settings:

  "workbench.browser.agentHostChatToolsEnabled": true,
  "workbench.browser.enableChatTools": true,
  "chat.agentHost.enabled": true,
  

• In Agents app, click on the option to select a workspace or folder, then click on Select Folders... Local Agent Host
  • 
• Select any folder or workspace. Ideally a front-end or full-stack project that would benefit from validating changes in a web browser.
• Verify that it says "[Local]" next to the name of the folder. This will validate that you're in a Local Agent Host session.
  • 
• Select the type of session. It doesn't matter if you use a Folder or Worktree type of session
  • 
• Send prompts that use the browser.
• Ensure that the integrated browser appears and is being used by the agent.

Scenarios to try

Some examples of things you can try:

• Try a few of the variety of the available tools. These have already been verified in the past in VS Code, but this verification is for how they might work specifically in Agent Host sessions within Agents App.
  • 
• Try broad instructions that would require using multiple tools. For example, ask it to open a website and do some action that would require the agent to click, type, take screenshots, navigate, etc.
• Try scenarios that would require the agent to make changes and then validate them using the browser, find any issues, and fix them. For example, this scenario: https://code.visualstudio.com/docs/copilot/guides/browser-agent-testing-guide#_step-2-ask-the-agent-to-build-a-calculator
• See what's the behavior when multiple of these sessions run at the same time with independent browsers

if so fine when on linux. Nothing work at Windows nor WSL nor Windows 11. Reason is that have no local agent in the list for choose anyhow.
