Water Coach

💧 Water Coach v1.5.1

First-time Setup references/setup.md

CLI Structure

water_coach.py <namespace> <command> [options]

Namespaces: water | body | analytics

Data Format

CSV Format

logged_at,drank_at,date,slot,ml_drank,goal_at_time,message_id

Key Rules:

• drank_at is MANDATORY - always required
• If user doesn't specify drank_at → assume drank_at = logged_at
• Cumulative is calculated at query time (not stored)
• Use drank_at to determine which day counts

Details at references/log_format.md

Audit Trail

Every water log entry captures:

• message_id: Links to the conversation message where user requested the log
• Auto-capture: CLI automatically gets message_id from session transcript
• Proof: Use water audit <message_id> to get entry + conversation context

# Check proof of a water entry
water audit msg_123
# Returns: entry data + surrounding messages for context

⚠️ Privacy Notice: The audit trail feature can read your conversation transcripts to link water entries with messages. By default, this is disabled (audit_auto_capture: false). To enable it:

# Edit water_config.json and set:
"audit_auto_capture": true

Why would you want this? If you need proof of water intake for medical/legal purposes, the audit provides conversation context showing exactly when you logged water.

Why disable it? If you discuss sensitive topics in your chats, you may prefer not to have that content read by the skill.

Rules (MUST FOLLOW)

1. ALWAYS use CLI - never calculate manually
2. LLM interprets first - "eu tomei 2 copos" → 500ml → water log 500
3. Threshold from CLI - run water threshold, don't hardcode
4. GOAL is USER'S CHOICE - weight × 35 is just a DEFAULT suggestion:
   • At setup: Ask weight → suggest goal → CONFIRM with user
   • On weight update: Ask "Want to update your goal to the new suggested amount?"
   • User can set any goal (doctor's orders, preference, etc.)
