You are helping me build the following AI agent workflow.

## Goal
Trello to Slack Task Move Alerts: Monitors a Trello board for card moves and posts the task name and status change to a specified Slack channel or user.

## Specification
- What it does: Monitors a specific Trello board for card movements between lists. When a task changes status, it extracts the task name and previous/new steps. It then formats this information into a bolded message and posts it to a designated Slack channel or user.
- Trigger: Triggered by an event (Event · on Trello card move)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Trello: Trigger and data source for task moves
  - Slack: Send notification messages
  - HTTP Request: Retrieve Trello board ID via API

## Known pitfalls, handle each one explicitly in your implementation
1. Trello's webhook history only retains events for a short window so you must handle missed events gracefully or use polling as a fallback.
2. Incorrect board ID configuration will cause silent failures so validate the board connection immediately after setup.

## Reference implementation
https://n8n.io/workflows/7616 (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.
