The paper proposes SkillCompiler, which turns the well-specified steps of an LLM agent's learned skills into validated programs and keeps LLM reasoning for context-dependent steps. It also reuses verified program assets across skills. The reported gains (up to 32.33% on task performance across five benchmarks and six model families) are self-reported, so readers should check the evaluation setup. The idea of trading flexible LLM reasoning for deterministic, verifiable code is useful for anyone building reliable agent systems.
Compile Away Uncertainty: Self-Evolving Agent Skills via Programmatic Compilation
arXiv:2610.39508v1 Announce Type: new Abstract: Self-evolving agent skills enable AI agents to accumulate and refine reusable procedural knowledge from interaction experience without updating model parameters. However, since such skills are typically represented as textual documents and executed through LLM reasoning, even previously learned procedures must be repeatedly interpreted and regenerated, introducing avoidable uncertainty into every execution. In contrast, program execution is deterministic and independently verifiable. Intuitively, transforming well-specified operations into executable programs can reduce reliance on LLM reasoning and, consequently, reduce execution uncertainty. Motivated by this intuition, we introduce SKillCompiler, a self-evolving skill framework that integrates programmatic compilation into the skill evolution process. Specifically, SkillCompiler adopts an executability-aware skill compilation strategy that decomposes skills into fine-grained operations, analyzes their executability, and constructs hybrid skill skeletons that retain LLM reasoning for context-dependent operations while compiling well-specified ones into validated programs. To avoid redundant program synthesis and enable executable knowledge to accumulate across evolving skills, we further design a program asset reuse mechanism that organizes validated programs as reusable assets, retrieves existing implementations whenever applicable, and synthesizes and verifies new programs only when necessary. Extensive experiments on five benchmarks and six model families demonstrate that SkillCompiler consistently outperforms state-of-the-art methods, achieving up to 32.33\% improvement in task performance.
