Wrapping up my advent of agentic humps by building tuatara: a self-mutating Atom aggregator that can invoke Claude to alter its own OCaml code if it runs into errors. Medice, cura te ipsum, and merry Christmas! https://anil.recoil.org/notes/aoah-2025-24
AoAH Day 24: Tuatara, an evolving Atom aggregator that mutates
Tuatara is a feed aggregator that integrates Claude to evolve and patch its own code when encountering parsing errors, embodying the concept of self-healing software.

I've built "unpac" today to make it possible to vendor _all_ (OCaml or other) package dependencies in a single git repo, using 100s of orphan branches and git worktrees. This makes agentic programming way more reliable as the agent has access to all the OCaml/OxCaml code.
