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
Helper Script
Use scripts/post.py for easier posting with automatic character validation: # Single platform ~/.local/bin/uv run ~/clawd/skills/postiz/scripts/post.py \ --platform x \ --content "Your tweet here" \ --schedule "2026-02-05T15:00:00Z" # Multi-platform with different content ~/.local/bin/uv run ~/clawd/skills/postiz/scripts/post.py \ --x "Short X version" \ --linkedin "Longer LinkedIn version with more detail" \ --bluesky "Bluesky version" \ --schedule "2026-02-05T15:00:00Z"
