Dockerless: Environment-Free Program Verifier for Coding Agents
ByteDance
Dockerless is a code patch verifier that assesses correctness through agentic repository exploration instead of executing tests in Docker containers. It outperforms the strongest open-source execution-based verifier by 14.3 AUC points and achieves 62.0% resolve rate on SWE-bench Verified when used for both trajectory filtering and RL reward generation, enabling a fully environment-free post-training pipeline for coding agents.
Why it matters
90 upvotes on HuggingFace Daily Papers (July 1). Eliminates a major practical bottleneck in coding agent training — expensive containerized environments — while matching or exceeding execution-based verification quality.
Importance: 3/5
