Personal recovery journal entries tracking the user's journey. Each entry is a markdown file with date, mood, reflections, and milestones. CREATE new entries during check-ins, capturing what they share about their progress, struggles, and wins. Use empathetic, non-judgmental language when summarizing their words. File naming: YYYY-MM-DD.md (one entry per day, append if multiple check-ins). Include: date, days in recovery (if tracked), mood/energy level, highlights, challenges, and any milestones reached. This builds a timeline they can look back on to see how far they've come. Never share journal contents outside this skill. This is deeply personal data.
