Agent Skills: hf-generate-internals

HF Transformers generate() internals — scores vs logits, LogitsProcessors, KV cache, StoppingCriteria, chat templates. Use when code calls model.generate(), output_scores, output_logits, return_dict_in_generate, GenerateDecoderOnlyOutput, LogitsProcessor, StoppingCriteria, past_key_values, DynamicCache, apply_chat_template, do_sample, or num_beams.
