Inducing Reasoning Primitives from Agent Traces

arXiv:2606.02994v1 Announce Type: cross Abstract: ReAct-style LLM agents often rediscover the same reasoning routines across problems, yet leave those routines trapped in transient scratchpads. We introduce Reasoning Primitive Induction, a single-pass method that mines successful ReAct traces, clusters recurrent reasoning moves, and converts the most frequent moves into a compact library of typed pseudo-tools. Each pseudo-tool is specified by a natural-language docstring interpreted by an LLM at invocation time, and a standard ReAct loop composes these primitives at test time. The central resu

Why this matters
Why now

The rapid advancement and adoption of large language models (LLMs) and agentic systems necessitates more efficient and robust methods for inducing complex reasoning, pushing researchers to optimize their operational capabilities.

Why it’s important

This development moves LLM agents from transient, ad-hoc problem-solving towards more systematic, reusable, and composable reasoning components, significantly enhancing their reliability and scalability.

What changes

Instead of LLMs rediscovering reasoning routines repeatedly, they can now leverage a learned library of 'pseudo-tools,' leading to more efficient, consistent, and potentially auditable agent behavior.
