## Scripts

```bash
# Validate post content
node scripts/validate-post-content.js --platform x --content "Your post" --media "img.jpg"
node scripts/validate-post-content.js --platform x --premium --content "Long premium post..."

# Schedule posts with optimal timing
node scripts/schedule-post.js --suggest-time --platforms "x,linkedin,tiktok"
node scripts/schedule-post.js --platforms "x,linkedin" --content "Hello" --time "2026-01-21T10:00:00Z"
```

## Core Workflows

### Content Creation
1. Define platform and goal
2. Write platform-optimized copy (load `posting-best-practices.md`)
3. Create hook using formulas (load `hook-writing.md`)
4. Add visuals, hashtags
5. Schedule optimal time

### Thread Creation
1. Choose type: educational, story, list, how-to
2. Write hook (most important)
3. Outline 5-15 posts
4. End with CTA

### API Posting
1. Authenticate: OAuth 2.0 (most) or OAuth 1.0a (X)
2. Upload media (chunked for large videos)
3. Validate content via `validate-post-content.js`
4. Create post with media IDs
5. Handle errors with exponential backoff

## Best Practices

1. **Content**: Native content > cross-posted
2. **Timing**: Test posting times for your audience
3. **Engagement**: Respond within 1 hour
4. **Tokens**: Refresh before expiry
5. **Rate Limits**: Exponential backoff (5s, 10s, 20s...)
6. **Media**: Resize images (<4MB), check video duration
