I could have sworn Claude Code could already do this before Fable.

Things get really magical when it starts working with adb to screenshot and debug Android apps

Claude Code could absolutely run Playwright and take screenshots, but I've never seen it wire together an ad-hoc "uv run --with pyobjc-framework-Quartz" plus "screencapture -l $windowID" mechanism to take a screenshot in a different browser when the Playwright setup failed to replicate the expected error.
