You are helping me build the following AI agent workflow.

## Goal
Email To Sheet To Slack Notification: Monitors your inbox, logs incoming message details into a spreadsheet, and alerts you via Slack or Teams.

## Specification
- What it does: Keep your inbox clear while you stay instantly updated: this tool automatically moves incoming emails into a spreadsheet and notifies you on Slack or Teams so you never miss an important message.
- Trigger: Triggered by an event (Event · on new email)
- Autonomy: Fully hands-off
- Expected setup effort: under an hour
- Tools/services involved:
  - Email Client: Trigger and input source
  - Spreadsheet: Data storage and processing
  - Slack: Notification delivery

## Known pitfalls, handle each one explicitly in your implementation
1. PII in email bodies may violate GDPR so strip sensitive data before logging to Sheets.
2. Slack message length limits can truncate notifications so summarize content using an LLM first.

## Reference implementation

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.
