@adrian_mirza_ @NicholasRuncie What's the next such idea? Feels like a low hanging fruit now, but encoding these rules is not trivial (see iupac blue book) - what was missing was all this massive execution power from agents 🔥

So cool when an idea becomes available and a bunch of groups tackle it almost simultaneously. Open smiles to iupac translation was missing for a while, and within 2 weeks @adrian_mirza_ and @NicholasRuncie independently released tools for it. Enabler here are coding agents! https://t.co/hYI1BIJ2Wk
