Native Runtime

The native runtime is preserved under lllm.runtimes.native.

Use it when you want transparent prompt assembly, dialog lineage, parser objects, tool schemas, or research workflows.

from lllm.runtimes.native import Dialog, Prompt, Role

system = Prompt(path="agent/system", prompt="You are a {style} assistant.")
dialog = Dialog(owner="agent")
dialog.put_prompt(system, prompt_args={"style": "careful"}, role=Role.SYSTEM)
retry = dialog.fork(last_n=1, first_k=1)

When native logic needs to cross the public boundary, wrap it with a tactic adapter instead of leaking native objects into service or package APIs.
