This skill should be used when working with reinforcement learning tasks including high-performance RL training, custom environment development, vectorized parallel simulation, multi-agent systems, or integration with existing RL environments (Gymnasium, PettingZoo, Atari, Procgen, etc.). Use this skill for implementing PPO training, creating PufferEnv environments, optimizing RL performance, or developing policies with CNNs/LSTMs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PufferLib - High-Performance Reinforcement Learning ## Overview PufferLib is a high-performance reinforcement learning library designed for fast parallel environment simulation and training. It achieves training at millions of steps per second through optimized vectorization, native multi-agent support, and efficient PPO implementation (PuffeRL). The library provides the Ocean suite of 20+ environments and seamless integration with Gymnasium, PettingZoo, and specialized RL frameworks. ## When to Use This Skill Use this skill when: - **Training RL agents** with PPO on any environment (single or multi-agent) - **Creating custom environments** using the PufferEnv API - **Optimizing performance** for parallel environment simulation (vectorization) - **Integrating existing environments** from Gymnasium, PettingZoo, Atari, Procgen, etc. - **Developing policies** with CNN, LSTM, or custom architectures - **Scaling RL** to millions of steps per second for faster experimentation - **Multi-agent RL** with native multi-agent environment support ## Core Capabilities ### 1. High-Performance Training (PuffeRL) …

How to install
mdr add foryourhealth111-pixel/vibe-skills/pufferlib@sha256:2614a6808c5a1024The line at the top of this page pins the label git:20260226.1632f40, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
