You are helping me build the following AI agent workflow.

## Goal
Send Birthday and Anniversary Reminders Gift Ideas: Daily AI alerts seven days before birthdays or anniversaries with personalized messages and three tailored gift ideas under $100.

## Specification
- What it does: Never forget a special day again as this workflow checks your contacts daily to send you warm, AI-generated alerts seven days before birthdays or anniversaries. You receive a clean message containing the person's name, age, relationship, interests, and three tailored gift ideas with price estimates ranging from $20 to $100. The system automatically calculates ages and handles year wrap-arounds so you are always ready to celebrate.
- Trigger: On a schedule (Scheduled · daily at 8 AM)
- Autonomy: You stay in control
- Expected setup effort: under an hour
- Tools/services involved:
  - Google Sheets: stores contact names, birthdays, relationships, and interests
  - Telegram: sends alerts with messages and gift suggestions
  - Groq Chat Model: generates personalized messages and specific gift ideas based on interests

## Known pitfalls, handle each one explicitly in your implementation
1. Repetitive prompts can cause the model to suggest the same generic gifts, vary the temperature parameter for more creativity.
2. Sending messages too frequently might annoy contacts, implement a cooldown timer if multiple events occur within a short window.
3. Personal data like names and ages must be sanitized before sending to prevent accidental exposure in logs.

## Reference implementation
https://n8n.io/workflows/15335 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
