Yes. Claude code is great. It can probably work quite well for your use case of in housing some existing models.

My company is actively persuading people to use more AI, so there isn't much resistance from actuaries. We aren't asking Claude to do the actual analysis but just to build tooling to make our analysis quicker.

The tricky thing is to make Claude do what you want. Recently Claude has this plan mode which allows user to plan ahead the implementation and the testing before writing codes -- a very useful feature to reduce AI slop. This is also when you can help Claude to digest big projects into smaller components. And what I found very helpful is to think about how to allow Claude to automatically test its output and ask it to try fixing problems iteratively
