Claude Fable is relentlessly proactive
"It turns out Fable had hacked up its own pattern for taking screenshots of browser windows. It was using Python to iterate through all available windows on my machine, then filtering for Safari windows with expected strings such as 'textarea' in the window name." "Based on a screenshot and a one-line prompt, Claude Fable 5 + Claude Code" proceeded to run a local dev server, cycle through multiple browsers, build its own CORS web server, inject JavaScript into templates, and navigate shadow DOMs to find and verify a fix. "Like I said, relentlessly proactive!"
