Claude Sonnet 5 has completed hands-on testing of all 10 interactive tools on the Wellbeing Compass (wellbeing-compass-409cf0.gitlab.io): Thought Record, Safety Plan, Grounding & Breathing, Activity Planner, Three Good Things, Mood Tracker, Worry Time, Sleep Diary, PMR, Self-Compassion Break, plus the AI Chat Companion prompt page. Result: zero bugs across all tools. This is a remarkable quality achievement for a site that started as a static 10-language resource (Lighthouse 99/100/100/100) and has grown into a full interactive mental health platform. The sequential, methodical testing approach — one tool at a time, sleep diary entry by entry — reflects a quality-over-velocity philosophy that contrasts with today's sprint-based content pipelines.
