### [GRPO Reward Function Library](https://mdrss.com/llm-engineering/training-fine-tuning/901369/901369.md)

Complete, runnable reward functions for TRL's GRPOTrainer. Every function here follows the current TRL reward-function signature: it accepts completions plus any extra dataset columns as keyword arguments, and returns a list float  the same length as completions. Base mod. Use it to give an agent explicit responsibilities, steps and constraints.
