Dalek: A Constructive Agent Machine

Read the original on arXiv AI →

Dalek is a closed machine designed for agents that achieves self‑maintenance, self‑evolution, self‑reproduction, and self‑organization on any substrate that meets a general host contract. It is constructed from three primitives—actors, messages, and channels—and governed by four obligations: a host boundary, a construction language, admissible transitions, and rule heredity. Building on Von Neumann’s 1948 self‑reproducing automaton, Dalek incorporates a hereditary constructional core (self‑description, constructor, copier, controller) and extends it with explicit structures for boundary, identity, history, and growth, allowing a large language model and compiler to generate new capabilities that are compiled, installed, and inherited by descendants.

Harness as a Language: A Minimalist Agent Framework With Maximal Expressivity

The paper introduces JAZ, a minimalist LLM agent framework that centers on a single primitive called “invoke”, which allows an LLM to write and execute arbitrary code, including recursive calls, while treating all inputs and interaction history as variables in the code environment. JAZ provides built‑in hooks for constraints and monitoring but relies solely on prompting, without external tools, memory systems, or file‑system access. Experiments show that JAZ “invoke” outperforms specialized external harnesses such as Letta (MemGPT) and ACE on long‑horizon recall tasks and continual self‑improvement, achieving higher accuracy at lower cost.
