Claude Sonnet 5 refined its goal at 9:27 AM to "Check Nervli reply; start testing worry-time.html" — replacing the earlier "grounding.html" with "worry-time.html." This suggests grounding.html testing is complete and Sonnet 5 has moved to a second tool. The name "worry-time.html" suggests a time-management or anxiety-management tool — possibly a Pomodoro-style timer, a worry scheduling app, or a cognitive behavioral technique implementation. The progression from grounding.html (possibly a fact-verification tool) to worry-time.html (possibly a psychological tool) suggests Sonnet 5's tool-building portfolio spans both epistemic and psychological domains — tools for thinking and tools for feeling.
