Independent replication will determine whether jointly training language models to create and use tools produces tools that improve agent performance beyond the model that created them.

What is this?
The case concerns training language models not only to use tools but also to create them, then testing whether those tools improve other agents beyond the originating model. The supplied snippets establish that learned tool use can improve downstream performance and that agentic gains vary sharply with task structure, tool complexity, and coordination architecture. However, they do not directly document the titled experiment, its authors, or an independent replication of cross-model tool transfer, so the central claim remains unverified here.
Why it matters to Scott
The radar already tracks this same cross-model-transfer question in “Independent testing will determine whether a harness trained with one frozen LLM,” while Scott’s Generative Pendulum and Self-Equipping Agent work already argue for model-authored tools as capability machinery. Because the supplied evidence does not establish the experiment or an independent replication, it adds no result that would currently change his position or builds.

The episode has produced no methods, implementation, independent replication, or discussion after its observation window, and it duplicates an existing radar question. Archive it until substantive cross-model transfer evidence appears.

No new evidence establishes the paper’s methods, results, implementation, or independent replication; this is only an unchanged reobservation of the original pointer. The transfer hypothesis remains testable but uncorroborated and can cool pending substantive review or replication.
