grail-miner

This skill should be used when setting up, managing, or optimizing Grail miners on Bittensor Subnet 81. Use it for GRAIL protocol tasks including miner setup, R2 storage configuration, model checkpoint management, GRPO rollout generation, performance optimization, competitive monitoring, and troubleshooting common issues like CUDA errors, upload failures, or low scores. Essential for miners working with verifiable post-training, SAT/GSM8K environments, or understanding the GRAIL incentive mechanism to improve competitiveness.
