Loop engineering = designing the repeat-and-refine cycle an AI agent runs through to complete a task, rather than just writing one prompt and taking the first output.
An eval is just two outputs side by side, with a few rules of what “good” looks like. Your job is to pick which one you'd actually send — and tell Claude what to change.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.
