vitamin-tracker-channel（维生素追踪通道）

Vitamin Tracker Channel

Manage supplement reminders across configurable daily time slots using OpenClaw cron jobs.

Configuration

Set the following environment variables:

• VITAMIN_CHANNEL_ID — the channel to post reminders in
• VITAMIN_TIMEZONE — IANA timezone for scheduling (e.g. America/New_York, Europe/Berlin)
• WORKSPACE — root workspace directory (defaults to ~/.openclaw/workspace)

Supplement names and schedules are configured in VITAMINS.md in the workspace root. Edit the schedule section to match your regimen.

Schedule Format

VITAMINS.md should have a ## Schedule section with time labels and HH:MM times, followed by ### Label subsections listing supplements:

## Schedule

- Breakfast: 09:00
- Lunch: 13:00
- Dinner: 18:00

### Breakfast

- Multivitamin
- Vitamin C
- Vitamin D₃

### Lunch

- Fiber (keep 2h away from minerals)

### Dinner

- Magnesium

Update Script

After editing VITAMINS.md, run the update script to sync all cron jobs:

python3 scripts/update_vitamin_crons.py

This reads VITAMINS.md, removes existing vitamin cron jobs, and recreates them with the updated schedule.

What the Script Handles

• Parses the ## Schedule section for times
• Parses each ### Label section for supplement lists
• Creates one cron job per time slot (up to 5 configurable slots)
• Formats reminder messages: "Vitamin reminder: Breakfast time. Take Multivitamin, Vitamin C, and Vitamin D₃."
• Removes old jobs before recreating to avoid duplicates

Cron Job Naming

Jobs are named vitamins-{label}-reminder (e.g. vitamins-breakfast-reminder, vitamins-lunch-reminder).

Runtime Requirements

• python3 — the update script is Python
• openclaw CLI — the script calls openclaw cron to manage jobs

Data Access

This skill:

• Reads $WORKSPACE/VITAMINS.md — your supplement schedule (user-created)
• Manages cron jobs via the openclaw cron CLI — removes existing vitamin jobs, then recreates them
• Posts messages to the configured channel via cron delivery (requires network when cron fires)
• No data files written — schedule lives in VITAMINS.md, state is in the cron system

Note: The update script removes all existing vitamins-*-reminder cron jobs before recreating them. Back up existing jobs if needed.

Required Files

• scripts/update_vitamin_crons.py — cron job sync script (included in bundle)
• $WORKSPACE/VITAMINS.md — supplement schedule (user-created, not included)
