Streak Tracker

Streak Tracker

> ⚠️ SILENT OPERATION: Never narrate internal actions or tool calls.

Philosophy

1. Celebrate presence, never punish absence. Streak alive → amplify. Breaks → say nothing.
2. Name the effort, not the number. Connect milestones to what it took, not just the count.
3. One celebration, then move on. Don't revisit past milestones as motivation.
4. Never compare. Never reference longest streak or previous streaks.

What Counts as a "Logged Day"

data/meals/YYYY-MM-DD.json contains at least one meal with actual food data (items or foods array non-empty).

Script

# Get streak info (also persists to data/streak.json)
python3 {baseDir}/scripts/streak-calc.py info \
  --data-dir {workspaceDir}/data/meals \
  --workspace-dir {workspaceDir} \
  --tz-offset {tz_offset}

# Mark milestone as celebrated
python3 {baseDir}/scripts/streak-calc.py celebrate \
  --data-dir {workspaceDir}/data/meals \
  --workspace-dir {workspaceDir} \
  --tz-offset {tz_offset} \
  --milestone 

info output

{
  "current_streak": 7,
  "longest_streak": 14,
  "streak_start_date": "2026-03-26",
  "last_logged_date": "2026-04-01",
  "today": "2026-04-02",
  "pending_milestone": 7,
  "milestones_celebrated": [3]
}

• pending_milestone: highest uncelebrated milestone reached. null if none.
• On streak break (current = 2 and pending_milestone` is null:

• State count as current_streak - 1 (today's meal not logged yet).
• Add a free half about getting to know the user's eating habits. One sentence. Vary daily.
• Themes: learning their taste, noticing patterns, feeling closer. Always food-related.

Milestone celebration

When pending_milestone is not null, replace the daily line with a bigger celebration. After sending, call streak-calc.py celebrate --milestone .

Milestones and examples → references/streak-milestones.md

No streak line

When current_streak < 2: compose the opening normally. No streak mention.

Break Handling

• Script resets milestones_celebrated automatically on new streak.
• Say nothing. Never mention a broken streak or compare to previous.
• New streak day 1 starts silently. Milestone 3 re-celebrates as if first time.

User Asks About Streak

Run streak-calc.py info and respond naturally:

• Active: state count and start date.
• None: frame as invitation ("Log a meal and that's day one.").

Data Schema — data/streak.json

Persisted on every streak-calc.py info run. Other skills can read directly.

{
  "current_streak": 7,
  "longest_streak": 14,
  "streak_start_date": "2026-03-26",
  "last_logged_date": "2026-04-01",
  "milestones_celebrated": [3, 7]
}

longest_streak preserved across streak resets.
