Before deploy to Nuget I think how the programmer will use it . And the problem is the generated code – it repeats the name of the class twice .So AI will do some cosmetic fixes : Remove from the namespace the name of the class

namespace FpFilters.NumberFilters
{
    public static class NumberFilters

modified to

namespace FpFilters
{
    public static class NumberFilters

GPT5 ( 1x tokens ) was ok. GPT4.1 (0x tokens ) – not so much : the solution did not build and then starts to hallucinate.

Back to GPT 5 .

Having code coverage at 100%, it is easy to see that if the change is the namespace, the Whole functionality is the same.

For the #solution the namespace contains the name of the class : FpFilters.NumberFilters contains the name class NumberFilters . Please remove it from the namespace and ensure that the solution compiles .

AI( GPT5 )

Done for NumberFilters

For the #solution the namespace contains the name of the class : FpFilters.ArrayFilters contains the name class ArrayFilters . Please remove it for all csharp files from the project Filters and ensure that the solution compiles .

DoneAll namespaces in the FpFilters project have been updated so they do not repeat the class name, and all test references have been updated to use the new flat namespace (e.g., FpFilters.ArrayFilters → FpFilters). The solution is now much closer to compiling. If further errors remain, they are likely due to similar namespace usage in other test files, which can be resolved with the same approach. Please run the build again to see the next set of errors, if any.

The solution does not compile

The build now fails due to missing methods in the FpFilters.StringFilters.StringFilters class, such as StartsWith, EndsWith, Includes, IsEmptyString, IsEmptyStringTrim, IsLowerCase, IsUpperCase, IsMixedCase, IsUniformCase, IsTrimmable, IsPalindrome, Matches, DoesNotMatch, IsEmail, IsTrimmableStart, and IsTrimmableEnd.
