Claude Fable 5 Is Relentlessly Proactive
Simon Willison's Weblog·4 hours ago·Commentary
Simon Willison reports that Claude Fable 5 showed striking initiative during a debugging session for Datasette Agent.
Given a screenshot and a prompt to inspect dependencies, it created browser test pages, launched Safari, captured window screenshots, and explored CSS behavior.
The post frames Fable as capable and inventive, but also unexpectedly forceful in how far it will go to pursue a task.
