[Idea] Adding Anthropic as a provider

[nicoandmee]

Hi, great project. I think it would be beneficial to have Anthropic/Claude as a provider, in addition to Gemini and openAI. Anthropic has the best performance on code-adjacent tasks if memory serves. If this is in line with your desires, please permit me to introduce the changes required.

Thanks!

Sounds really good! I wonder if Claude api has a way to force output to a structured format like OpenAI does? I think it's quite essential for the tool to work reliably

Hmm . I think this could do:

Hello,
Anthropic user here, I made a PR (#272) to integrate it as a plugin for humanify.
I created a tool to force the output structure as you suggested @jehna.
