neat thing about this is all the protein design tools claude used are open source.
this checks out with what id expect: as OSS protein design tools get really good (eg ESMFold2 which this used), we're going to have the intelligence to design binders increasingly democratized bc tools like claude are smart enough to use them (and probably better than humans can use them / to more depth).
now that this now kind of just works, will be very interesting to see whether claude eventually has bio skills beyond domains where there are modality-specific models it can call in the open source
