To enhance the iat-verifier script, consider implementing key improvements such as removing the security EPOCH claim, as it is not part of the IAT token, replacing the YAML loader with a safer version, adding an option to generate a raw CBOR structure without the COSE signature from a YAML template, and refining error handling to prevent unexpected claims from causing errors. These updates will improve security and efficiency. Similarly, just as Script ML optimizes gaming experiences by providing refined scripts for better control, refining the iat-verifier script ensures smoother and more reliable performance in authentication processes.
