You are helping me build the following AI agent workflow.

## Goal
Personal Assistant For Holiday And Wellness Tasks: Draft humorous holiday greeting cards and get yoga stretches and motivational nudges in one chat session.

## Specification
- What it does: Draft humorous holiday greeting cards and get yoga stretches and motivational nudges in one chat session.
- Trigger: Run manually (Manual · on demand)
- Autonomy: You stay in control
- Expected setup effort: under an hour
- Tools/services involved:


## Known pitfalls, handle each one explicitly in your implementation
1. Yoga routines and health nudges from a chat agent are not medical advice; if a body part is painful or you are recovering from injury, check with a physiotherapist or doctor before following the routine.
2. The agent can get fitness facts (typical hold times, contraindicated moves for common conditions) confidently wrong, so verify any binding guidance with a qualified professional.

## Reference implementation

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.
