llms.txt validation will be supported in Chrome devtools :)

Chrome DevTools will add support for validating llms.txt files, enabling developers to check the validity and correctness of their llms.txt configurations directly within the browser's developer tools. This enhancement simplifies the process of ensuring llms.txt files comply with their specification, making it easier for developers to implement AI model discovery and interaction standards.
