RecreationWorld: Scalable and Verifiable Environments for Hybrid Computer-Use Agents

HF ★ 25 · Shuai Bai, Jiayong Deng, Yikun Fu… · HF Mirror

To address the flaw of current computer-use agents separating GUI interaction from code development and failing to adapt to real hybrid workflows, this paper proposes RecreationWorld, a reproducible and verifiable test framework across 5 types of systems, paired with RecreationBench, a 250-task benchmark covering multiple domains. Tests show that the current state-of-the-art GPT-6 Astra only has an overall pass rate of 58.1%, and a full test case pass rate of only 2.8%. Existing agents’ ability to replicate interactions and computational outputs is far weaker than their ability to replicate static interfaces, leaving huge room for improvement.

CodeMidas: Scaling Agentic Coding RL Environments from Code Itself

HF ★ 21 · Bowen Ye, Lei Li, Shicheng Li… · HF Mirror

To solve the problem that existing coding agent RL training tasks rely on artifacts such as development work orders and commit records with limited coverage, this research proposes the CodeMidas automated pipeline. Taking only source code as input, it can automatically extract functions from open source code repositories, build verification tests, and filter out training tasks, constructing a dataset of 5545 tasks covering 23 languages and 15 domains. Agents trained with this dataset achieved a maximum score improvement of 17% across 5 benchmarks, confirming that source code can serve as a highly scalable source for coding RL training environments.

EvoOntology: A Self-Evolving Ontology Layer for Data Agents

HF ★ 15 · Meiduo Chong, Shaolei Zhang, Ju Fan… · HF Mirror

To address the agent-data gap when data agents process heterogeneous data, and the issue that existing direct source probing and manual semantic layer solutions are difficult to adapt to large-scale scenarios, this paper proposes EvoOntology, a self-evolving ontology layer: packaged as an MCP service with three levels, paired with an autonomous construction agent and a verification-enabled attribution-guided self-evolution mechanism. Experiments across multiple benchmarks and multiple base LLMs show that its performance is significantly better than existing solutions, effectively bridging the gap.

Grounded Skill Synthesis from Code at Scale for Agentic Intelligence

HF ★ 8 · Yongqi Tong, Pan Wang, Hang Wang… · HF Mirror

To solve the pain points of existing agent skill acquisition that relies on specific environment interactions and lacks executable verification, the research proposes the fully automated Code2Skill pipeline, which can extract implementable, verifiable agent skills from open source code. Its million-level skill library built on nearly 20,000 GitHub repositories can improve the average model performance by 11.7%, outperforming trajectory-based skill libraries. The pass rate of skills extracted from AI-generated code is basically on par with that of human-written code.

GraphSkillEvo: Evolutionary Optimization of Graph-Structured Agent Skills

HF ★ 3 · Rui Sun, Zhi Zheng, Zhenkun Wang… · HF Mirror

To address the pain points of unstructured skill optimization for LLM agents that lack clear workflow guidance and have low optimization efficiency due to the large unconstrained natural language search space, this research models skills as graph structures (nodes correspond to execution steps, edges correspond to context jumps), and proposes GraphSkillEvo, a population-based evolutionary optimization framework, which achieves more comprehensive skill space exploration than pure LLM self-iteration through mutation and crossover operators. Tests across 5 types of benchmarks show it consistently outperforms the baseline SkillOpt, with a maximum accuracy improvement of 4.01%.

Your Agent Aced the Task. Will It Do It Again?

Hugging Face

This paper conducts research targeting the flaw of current agent evaluations only looking at single task pass rates, finding that even if an agent completes a task with full marks for the first time, its success rate will drop sharply when encountering out-of-distribution scenarios such as fine-tuned environments, added interference items, and minor adjustments to task rules. The research calls for including repeated execution stability and out-of-distribution robustness into core evaluation indicators to avoid overestimating their actual deployment capabilities.

Async GRPO with LoRA across HF Jobs: a bucket, a proxy, and no NCCL

Hugging Face

This paper targets LLM RLHF training scenarios, and proposes a LoRA asynchronous GRPO training solution adapted to the Hugging Face ecosystem. It adopts two core designs: bucketed data processing and proxy task scheduling, completely eliminating the NCCL collective communication dependency required for traditional distributed training, without the mandatory requirement for homogeneous clusters, greatly reducing the threshold for training deployment, and achieving a significant improvement in cross-job resource reuse efficiency compared to existing baselines.

Harness Engineering for Self-Improvement

Lilian Weng

The concept of Recursive Self-Improvement (RSI) was first proposed by I.J. Good in 1965, referring to “superintelligent machines” with intelligence far exceeding humans that can independently design better systems to achieve self-iteration. In 2008, Eliezer Yudkowsky clarified that its core is self-feedback logic: AI relies on existing intelligence to optimize and generate the cognitive mechanism of its own intelligence. There are currently two paths for RSI in the AI field: directly rewriting its own weights, or optimizing the training pipeline in a broad sense.
