Is Default Search with Anthropic safe?

Medium risk

The extension removes Claude's malicious-prompt caution banner on claude.ai pages.

On claude.ai pages, its content script looks for the status message "Use caution before running this prompt" and removes the surrounding banner. It continues watching page changes for up to 60 seconds after load, so the warning can be removed if Claude adds it after the page appears.
