AoAH Day 25: Claude OCaml Marketplace for all your festive coding needs / Dec 2025

I'm somewhat frazzled after managing to get through 25 days of agentic coding. It hasn't actually been that much physical work, but I underestimated just how much my brain would be in full gear multitasking across so many terminal windows and ideas. My outbound queue that I didn't manage to write up is enormous: I have sessions running with OxCaml experiments, io_uring webservers, implementations of ATProto, a pure OCaml Parquet, and some even stranger ideas I won't go into now!

In the past, my computer systems brain was limited by the speed of coding, but now it feels like we're entering a different age. I'll reserve my longform thoughts on all of this for the new year as I need to head into Christmas festivities, but I wanted to leave you all with my Claude Code OCaml marketplace in case you want to try this stuff for yourself!

Claude Skills and marketplaces

Claude has made it very simple to distribute plugins. I just created a GitHub avsm/ocaml-claude-marketplace and kicked off Claude's own development plugin to develop plugins with. I then fed it all my skills and asked it to generalise them a bit. They'll likely need some work to generalise beyond me, but feel free to send in PRs!

I'll be back in the new year with more thoughts, but in the meanwhile, I hope you all have a very good holiday and a chance to recharge! It's going to be a mad 2026...
