Frequently Asked Questions

Can Claude Code post mixed carousels with photos and videos to Threads?

Yes. The Upload-Post skill supports mixed carousels on Threads, allowing you to combine up to 10 photos and videos in a single post. Just provide the media URLs in the API call and Upload-Post handles container creation and publishing through the Threads API.

How does cross-posting between Threads and Instagram work?

When you include both "threads" and "instagram" in the platform array, Upload-Post publishes your content to both platforms in a single request. Each platform receives an optimized version of the content that meets its specific requirements, so you maintain quality on both without extra configuration.

What are the text character limits for Threads posts?

Threads supports up to 500 characters per post. If your text exceeds this limit, consider using the reply threading feature to break your content into a multi-post thread. The Upload-Post skill will return an error if the text exceeds the platform limit, so you can adjust before re-posting.

What media formats does Threads support through the skill?

Threads accepts JPEG, PNG, and WebP images, as well as MP4 and MOV video files up to 5 minutes long. Upload-Post automatically validates your media against these requirements and provides clear error messages if adjustments are needed. For video, it also handles transcoding if your file is not in a supported codec.

Is the Upload-Post Threads skill free to use?

The skill itself is free and open source. Upload-Post provides a free plan with 10 uploads per month across all platforms, including Threads. Paid plans start at $12/month for higher volume publishing with features like scheduling, analytics, and advanced video processing.
