Tweet Pipeline

Automate tweet posting from a Notion content calendar. Draft tweets in Notion, set status to "Approved" with a scheduled time, and this pipeline handles the rest.

Workflow

Notion DB (Tweet Pipeline)
  ├── Status: Pending → Agent drafts tweet
  ├── Status: Approved → Heartbeat picks up
  │     ├── Future time → Schedules one-shot cron
  │     └── Past due → Posts immediately
  └── Status: Posted → Done (updated by poster)

Notion DB Schema

Usage

python3 scripts/tweet_poster.py             # Check and schedule
python3 scripts/tweet_poster.py --dry-run   # Preview without scheduling

Key Lessons

• One-shot crons for exact times — don't batch-post from heartbeat, schedule each tweet individually
• X Free tier: 1,500 tweets/month, 280 char limit, no media upload via API
• Track scheduled tweets in a state file to avoid duplicate scheduling

Files

• scripts/tweet_poster.py — Scheduler (reads Notion, creates crons)
• scripts/tweet_post_one.py — Poster (called by each cron job)
