Got this working in a preliminary way with local containerized environments for Copilot agent via https://github.com/dagger/container-use/pull/91. Going to fix it up, but could use some Windows wizards' support.
https://github.com/dagger/container-use (cu) is improving daily. Happy to help get it working if you're hitting anything (we're all in dagger.io discord). Last night I tried it with Amazon Q Developer CLI chat (with claude-3.7-sonnet), which I hadn't touched before (will PR how-to to the README today). MCP integration just worked for me. Figured out where to put the agent rules for Q and how to restrict to just the tools from cu. I kicked off three instances of Q to modify my flask app project with the same prompt in parallel (don't step on the local source) and got three variants to review in short order. I merged the one I liked into the repo and tossed the rest.
