I have 15 years of experience with Python however in this project, I didn't coded anything. Just Vibe coded. Putting errors from the console into chat.

Claude 3.7 Sonnet Thinking model used in this (using Github Copilot).

Documentation is also available at https://email-deliverability.readthedocs.io/en/latest/ which is also fully vibe coded.

Even the architecture diagram (https://email-deliverability.readthedocs.io/en/latest/overvi...) is also vibe-coded into mermaid diagrams.
