We open-sourced two RL environments on OpenEnv - Phantom Grid (visual memory) and Spreadsheet (stateful editing). Live on HuggingFace as Docker Spaces. We built these because most agent benchmarks only test one-shot retrieval. They don't tell you if an agent can carry state across steps, recover mid-task, or edit a workbook without silently breaking a downstream sheet. RL researchers need environments that actually test that, and right now there aren't many. Both use OpenEnv's reset/step/state interface, so they plug straight into existing training pipelines. Blog:

We built an RL environment where LLM agents have to navigate a hidden-state grid using 18 tools and 3 of which are traps. Best model so far scores 0.31. Target is 0.6. Fog-of-war. Memory pressure. Distractor tools. The things benchmarks usually skip.
