You are helping me build the following AI agent workflow.

## Goal
Event Follow-Ups with Multi-Channel Outreach: After an event, the agent enriches attendee data with LinkedIn insights, scores lead priority using GPT-4.

## Specification
- What it does: Turn event attendees into qualified leads by automatically enriching their data with LinkedIn insights and scoring priority using AI. You receive tailored outreach messages for email or LinkedIn that your team can send immediately, while all interactions are logged in your CRM and teams stay alerted via Slack.
- Trigger: Triggered by an event (Event · on webhook POST from event platform)
- Autonomy: You stay in control
- Expected setup effort: a few focused days
- Tools/services involved:
  - n8n: Workflow orchestration and automation logic
  - OpenAI Chat Model: Analyzing engagement and generating personalized messages
  - HubSpot: CRM integration for contact notes and follow-up tasks
  - Postgres: Logging interaction history and analytics data
  - Send Email: Delivering personalized follow-up emails to leads

## Known pitfalls, handle each one explicitly in your implementation
1. Enrichment data may be incomplete or outdated, so include fallback logic to skip leads with missing critical contact info.
2. HubSpot property mapping errors can cause silent failures, so verify field IDs in the test environment before going live.

## Reference implementation
https://n8n.io/workflows/10282 (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.
