You are helping me build the following AI agent workflow.

## Goal
Lead Scoring & Auto-Assignment: New GoHighLevel contact? GPT-4 scores it 1-100, tags the lead, assigns a rep, and pings Slack for hot prospects.

## Specification
- What it does: Get new leads routed instantly: GPT-4 analyzes your contact's data to score them 1, 100, tags their status in GoHighLevel, assigns the right rep, and alerts you on Slack for hot prospects.
- Trigger: Triggered by an event (Event · on new contact in GoHighLevel)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - GoHighLevel: Contact management and lead assignment
  - OpenAI: Lead scoring and categorization via GPT-4
  - Slack: Alerting on hot leads

## Known pitfalls, handle each one explicitly in your implementation
1. GoHighLevel tag names are case-sensitive and must match exactly, verify the spelling of tags before mapping them in the workflow.

## Reference implementation
https://n8n.io/workflows/11408 (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.
