You are helping me build the following AI agent workflow.

## Goal
Freight Quote Automation via WhatsApp: Collects freight details via WhatsApp chat, calculates LTL quotes with commission using Warp API, and sends the final price back instantly.

## Specification
- What it does: Collect freight shipment details and deliver instant LTL quotes directly through WhatsApp. The system identifies the sender in HighLevel, uses an AI agent to gather missing logistics data via chat, calculates the final price with your commission, and sends the quote back to the customer automatically.
- Trigger: Triggered by an event (Event · on new WhatsApp message)
- Autonomy: Fully hands-off
- Expected setup effort: a few focused days
- Tools/services involved:
  - WhatsApp Business Cloud: Receive and send messages
  - HighLevel: Contact lookup and management
  - Google Gemini Chat Model: Conversational data collection
  - Redis Chat Memory: Maintain conversation context
  - HTTP Request: Call Warp API for quotes

## Known pitfalls, handle each one explicitly in your implementation
1. Redis memory keys must include unique session identifiers per customer to prevent quote data from bleeding between different users chatting simultaneously.
2. WhatsApp message templates require pre-approval for outbound quotes, so ensure your initial trigger uses a valid template ID to avoid message rejection.

## Reference implementation
https://n8n.io/workflows/16385 (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.
