You are helping me build the following AI agent workflow.

## Goal
ICP Prospect List Builder: Finds ICP-matched companies via Surfe, enriches contacts with verified emails and phones, then syncs them to HubSpot.

## Specification
- What it does: Get a ready-to-use list of Ideal Customer Profile matches with verified emails and phone numbers automatically synced to your HubSpot. You can trigger this process manually or on a schedule to receive clean, validated prospects without any manual data entry.
- Trigger: Run manually (Manual · on demand or scheduled)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - Surfe: ICP company search, people discovery, and contact enrichment
  - HubSpot: Storing and managing enriched prospect contacts
  - Gmail: Sending completion notifications to the user

## Known pitfalls, handle each one explicitly in your implementation
1. Invalid JSON structures in the Surfe response will crash the workflow, so add a try-catch block or error handling node before parsing data.

## Reference implementation
https://n8n.io/workflows/7130 (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.
