The Empire, Long Divided, Must Unite: Architectural Convergence in Three LLM Agent Harnesses (arXiv)
paper · Story page
A source-level reading of deepagents, pi and dsh at pinned commits finds harnesses that set out from opposite philosophies meeting at the same five parts: a commoditised loop, an append-only replayable session record, model quirks kept as data, progressive disclosure of context, and explicit extension seams. The authors don't claim independent invention.
In plain words
- Researchers compared supporting software for three coding assistants and found the designs settling on the same five elements.
- The shared design centers on a basic work cycle backed by a replayable record that never deletes earlier entries.
- It handles variation by storing system quirks as data, revealing information gradually, and defining clear places to add features.
- Two mature projects approached this design from opposite directions, while the third contained all five elements.
- The study says surrounding software increasingly limits coding-assistant behavior, so these shared design choices matter to builders.
