1. Claude Fable Is Relentlessly Proactive — Deep Dive into Agent Autonomy
Simon Willison analyzes Claude Fable 5's agent behavior: it doesn't just write code, it autonomously opens browsers to verify fixes, explores dependency trees, and chains actions without waiting for instructions. Unlike typical Agent Plan workflows, Fable's proactivity marks a shift from "tool" to "autonomous collaborator" in agent evolution.

2. Reducing AI-Generated Frontend Slop with Qt Style
A simple trick: asking AI to generate Qt-style interfaces dramatically reduces the typical "AI slop" feel — dense controls, clear borders, conservative colors produce more tasteful results than generic modern web styles.
