What's Wrong?

Claude in Chrome (v1.0.68) blocks all interaction with lovable.dev — screenshot, JavaScript execution, read_page, find, and navigate all fail. This is a regression: lovable.dev was fully accessible earlier in the same Cowork session (confirmed by session transcript showing successful JavaScript injection, screenshots, and click interactions on the same domain).

What Should Happen?

lovable.dev should be accessible like any other website when the user has granted "On all sites" permission. lovable.dev was working earlier in this same session.

Error Messages/Logs

screenshot → "Permission denied for this action on this domain"
javascript_tool → "Permission denied for JavaScript execution on this domain"
read_page / find → "Permission denied for reading pages on this domain"
navigate (new tab) → "Navigation to this domain is not allowed"

Steps to Reproduce

1. Open Cowork session with Claude in Chrome connected
2. Navigate to any lovable.dev project URL (e.g., https://lovable.dev/projects/...)
3. Attempt any browser automation tool (screenshot, javascript_tool, read_page, navigate)
4. All fail with permission/domain errors

Additional Information

lovable.dev is a primary development tool for this project. The block prevents autonomous development workflows where Claude drives Lovable to implement, test, and deploy code changes — forcing manual copy-paste of every prompt and code change. github.com being blocked prevents filing issues, reviewing PRs, and inspecting source code.
