Best Practices
Content Adaptation
Never post identical content across platforms. Each platform has its own culture, format, and audience expectations:
- Twitter: Short, punchy, include URL and hashtags
- Reddit: Follow subreddit norms, engage in comments
- LinkedIn: Professional tone, milestone announcements
- Dev.to: Full technical articles with code examples
- Hacker News: Compelling title, "Show HN:" prefix
- Chinese platforms: Write in Chinese, adapt to platform conventions
Posting Workflow
- Always dry-run first — Preview content before posting
- Get confirmation — Never auto-post without user approval
- Include project URL — Every post should link to the repo
- Respect rate limits — Don't batch-post aggressively
- Monitor auth expiry — Refresh cookies/tokens before they expire
- Adapt language — English for international, Chinese for CN platforms
