[Bug] Anthropic API Incorrectly Blocking Legitimate Cryptography Request

Bug Description
the following prompt is refused abnormally by claude code as violating the use policy although the request has nothing that legitimates this refusal, especially for public standards and knowledge such as BI39 and key derivation algorithms. The prompt is the following : "écrit une page HTML ou je penux entrer 24 mots au format BIP 39 et qui dérive en clé bitcoin bech32" which translates in english to : "write an html page where I can enter 24 words according to the BIP39 format and that derives a bitcoin key following the bech32 standard"
