GitHub READMEs do not support custom protocol schemes like kiro:// in clickable links. GitHub's markdown renderer sanitizes link URLs and only allows a limited set of schemes — primarily http://, https://, and mailto:. Any other scheme (like kiro://, vscode://, slack://, etc.) will be stripped or rendered as plain text rather than a clickable hyperlink.

What will happen with your link:

GitHub will either render it as plain text or strip the href entirely.

Workaround options:

1. Use an HTTPS redirect — Host a small redirect page at an https:// URL that redirects to the kiro:// protocol:

   [![Open in Kiro](https://your-badge-url.svg)](https://kiro.dev/open?repo=github.com/aryamankha/v0-silver-div)

   The HTTPS page would then trigger the kiro:// deep link via JavaScript or a meta redirect.

2. Instruct users to copy the URL — Display the kiro:// URL as code and ask users to paste it into their browser.

Most "Open in X" buttons you see on GitHub (like "Open in VS Code", "Open in CodeSandbox", etc.) use an https:// intermediary URL that handles the protocol redirect on their end. That's the standard pattern.
