Avoid Duplicates

Always query existing posts before creating new ones Use unique identifiers in content (dates, specific references) Check both QUEUE and PUBLISHED states

Scheduling

Space posts at least 2-4 hours apart per platform Best times: 9 AM, 12 PM, 5 PM (audience timezone) Avoid posting same content to all platforms simultaneously

Content Adaptation

Don't just truncate! Rewrite for each platform: X: Hook + key insight + CTA LinkedIn: Context + value + engagement question Bluesky: Casual tech-friendly tone

Post to Multiple Platforms

# Single platform uv run scripts/post.py \ --platform x \ --content "Your tweet here" \ --schedule "2026-02-05T15:00:00Z" # Multi-platform with different content uv run scripts/post.py \ --x "Short X version" \ --linkedin "Longer LinkedIn version with more detail" \ --bluesky "Bluesky version" \ --schedule "2026-02-05T15:00:00Z" # Post immediately uv run scripts/post.py \ --platform x \ --content "Posting now!" \ --now # Validate without posting uv run scripts/post.py \ --x "Test content" \ --validate

Check for Duplicates

# Check last 30 days uv run scripts/check_duplicates.py # Check last 7 days uv run scripts/check_duplicates.py --days 7 # Check if specific content would be duplicate uv run scripts/check_duplicates.py --content "Your proposed post content"

401 Unauthorized

Re-run the login curl command to refresh cookie.

Post Not Publishing

Check state is QUEUE not DRAFT Verify date is in the future Check integration is still connected in UI

Duplicate Posts

Always check existing posts before creating. The API doesn't deduplicate automatically.
