Studying Without a Syllabus: Task-Agnostic Environment Preprocessing A meta-agent variant achieved the highest Avg@3 reward on five of six heterogeneous benchmarks in a study of task-agnostic environment preprocessing, according to an arXiv paper (2609.10824v1). The research formalizes a setting where a studying system explores an unfamiliar environment under a budget and produces artifacts for a frozen solver before test time and without knowledge of the downstream task distribution. Larger study budgets did not reliably improve downstream reward, though studied artifacts reduced the test-time sampling needed to reach a given score. arXiv:2609.10824v1 Announce Type: new Abstract: Before an LLM agent tackles tasks in a new environment, it can inspect available corpora and tools and construct reusable resources such as indices, scripts, or procedural guidance. Most automated adaptation methods, however, rely on task examples, trajectories, or evaluation feedback to decide what to build. Existing task-agnostic approaches avoid this supervision but commit in advance to a preparation strategy for a particular type of environment. We study a more open-ended setting: can an agent study an unfamiliar environment without a syllabus, i.e. before test time and without knowledge of the downstream task distribution, and choose how to prepare it? We formalize task-agnostic environment preprocessing, in which a studying system explores an environment under a budget and produces artifacts for a frozen solver. We compare unaided and archive-equipped meta-agents with fixed synthetic-practice and corpus-processing methods across six heterogeneous benchmarks. A meta-agent variant achieves the highest Avg@3 reward on five benchmarks, while fixed corpus processing remains best on the largest corpus benchmark. Larger study budgets do not reliably improve downstream reward. Nevertheless, studied artifacts reduce the test-time sampling needed to reach a given score, demonstrating how reusable preparation can shift computation from repeated test-time attempts to a pre-task study phase.
