I’ve had the greatest success with Claude. The company I work for basically let us all go wild with a few to trial, and Claude has been the best for all of us—even better than GitHub Copilot.

I pay for my own pro plan outside of work and use the VSCode plugin. I’d say read the quickstart guide and experiment with it. Start off with having it do smaller changes and don’t be afraid to be verbose. The more context, the better. Point it to existing files you want to follow the patterns of and model after; give it links to resources for best practices, etc. You can also use it in “plan mode” if you want to see its proposed approach before it starts editing.

I also recommend leaving it so that each change it makes requires your approval (it will do this by default and you can step through everything). That way you always have some control and if it does something dumb, you can stop it at that step and pivot with a different instruction. Alternatively, if you want to see it go ham and carry everything out without approval at each step, you can enable auto-accept.

Once you get into it, start looking into how to craft instruction files. You can have those at your disposal for things like writing tests, language-specific guidelines and practices, etc. That way you can make sure it uses those as a reference so you don’t have to give it the same instructions over and over with every prompt.

If you hate writing tests, I’ve had really good luck letting it handle that. I tend to use it more for the bulk tasks that suck. For things where I want more control, I work with it on a piecemeal basis in my project.
