# CodeMidas: Scaling Agentic Coding RL Environments from Code Itself > Source: > Published: 2026-09-21 03:00:04+00:00 Training capable coding agents via reinforcement learning (RL) requires diverse tasks with reliable verifiers. Open-source codebases offer a rich source of such tasks, while existing methods typically rely on development artifacts such as issues and commits, limiting the range of tasks that can be e
