You are helping me build the following AI agent workflow.

## Goal
Real-Time ClickUp Time Tracking to HubSpot Project Sync: Updates HubSpot project hours in real-time whenever time is logged on a ClickUp task.

## Specification
- What it does: You instantly see your ClickUp task hours appear in your HubSpot projects as soon as you log time, keeping your project data accurate without manual entry. The agent automatically matches your logged work to the correct HubSpot sprint and updates the actual hours for you.
- Trigger: Triggered by an event (Event · on time entry update in ClickUp)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - ClickUp: Trigger and fetch task time data
  - HubSpot: Update project hours via HTTP Request
  - HTTP Request: Interact with HubSpot custom objects
  - Code: Process task data and map sprint categories

## Known pitfalls, handle each one explicitly in your implementation
1. Incorrect property IDs will cause silent failures so verify the custom object schema before deploying the workflow.
2. Timezone mismatches between ClickUp and HubSpot can skew reports so normalize all timestamps to UTC before sending.

## Reference implementation
https://n8n.io/workflows/6831 (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.
