My everyday work is with a very legacy framework, and I've noticed that for the best results, I end up smacking on so many skills, additional tools, and so on to the agent, that at this point it's a harness specifically designed for this project.

While this was the result of necessity, I think it helps a ton to have the harness fit your specific dev experience, like an IDE full of the specific plugins you'd want - just not an ide, because ides are OVER.
