You are helping me build the following AI agent workflow.

## Goal
Social Media Content Automation: Pulls post ideas from a Google Sheet, generates platform-specific text via AI, publishes to LinkedIn and X, logs the activity.

## Specification
- What it does: You save time by having your social media content created and published to LinkedIn and X automatically from ideas in your Google Sheet. You receive email confirmations once each post is successfully logged and shared across platforms.
- Trigger: On a schedule (Scheduled · daily)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Google Sheets: Content planning and tracking
  - OpenAI Chat Model: Generating tailored content
  - LinkedIn: Publishing posts
  - X (Formerly Twitter): Publishing posts
  - Send Email: Sending notifications

## Known pitfalls, handle each one explicitly in your implementation
1. LinkedIn requires a specific OAuth2 flow for posting, so you must register an app in their developer portal and handle token refreshes manually.
2. Platform terms of service may prohibit fully automated posting without human review, so consider adding a manual approval step in the spreadsheet.

## Reference implementation
https://n8n.io/workflows/3104 (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.
