Firt review the following promps to do a scientific literature review and write a updated prompt to a new text file. 
You are going to do a scientific literature review for synthetic ECG evaluation methods and dowload those papers to the folder at /work/vajira/DL2026/ECGEN-Eval/literature_review_claude in structured way. Consider last 3 years to do this literauter review. First write your literarure review plan to a file in the same folder and then follow it. If you cannot dowanload papers list them in a md file with corresponding links so I can help you to download them latter. 
Synthtic ECGs means generated ECGs from generative models in machine learning like GAN, Diffusion, Flow matching, VAE etc. My main focus is to find evaluation methods and loss functions used in these paper. So, you are allowed to defin best queries to find relevant papers.  At the end exclude the downloaded papers (original source files) from git commits.
