Repost your best performer with a fresh angle
Ask your assistant to find your best post. It reads your results from Socialync, explains why it worked, writes a new post on the same idea with a different hook, picks a good time and schedules it after you approve.
Needs a paid plan. Connect an assistant first if you have not: setup guides.
The prompt
Find my best performing Instagram post from the last 30 days. Tell me why it worked using the numbers, then write a new post on the same idea with a different hook. Suggest a time from my best posting windows. Show me the post and the time, and schedule it only after I say yes.
Swap in your own details. Example links and names are placeholders.
What the assistant does
Each step names the Socialync tool the assistant calls. A step with no tool is the assistant's own work or yours.
- 1
Pick the brand
Your assistant picks the brand, or asks if you have several.
list_profiles - 2
Find the best post
It ranks your posts on Instagram by engagement and keeps those rated good or viral, using each post's date to stay inside the last 30 days. A rating compares a post with your own usual on that platform.
get_top_posts - 3
Learn why it worked
For the winner it reads the full picture: views, likes, comments, shares and, for a video, watch time and where viewers stopped. The same post on your other platforms comes alongside.
get_post_insights - 4
Write the new post
Socialync has no repost or re-share tool, so a repost here is a new post on the same idea with a different hook. The old caption is available to work from. Socialync does not return the image or video, so you supply it again: an image link, an image attached in the chat, or a video uploaded in Socialync.
- 5
Pick a time
It reads your best posting windows for that platform and proposes a time in them.
get_best_times - 6
Check, show and schedule
It validates the post, shows it with the time, and on your yes schedules it.
validate_postpublish_scheduled - 7
Read the calendar back
It lists the calendar to confirm the post is in.

What you will be asked to confirm
- The new post in full: text, media and platforms.
- The time it picked from your best windows.
- The yes that schedules it.
Socialync tells your assistant to show you the exact post and wait for your yes in the chat before it publishes, schedules, replies or cancels anything. The publishing tools are marked as destructive, so clients that honor that also ask you to allow each call. You can switch on a confirmation dialog on the API Keys page that shows the exact post inside clients that support it. Socialync records who approved each post and when.
What you need
Plan
A paid plan (from $20 a month). Analytics and best times are part of Socialync's paid plans.
Connected accounts
The platform you want to repost on connected in Socialync, with some post history.
Assistants
Claude (claude.ai, Desktop and Code), ChatGPT, Grok, Cursor, Codex and Gemini CLI connect to Socialync. Any other assistant that supports MCP can too.
Also
- The image or video for the new post. A video needs to be uploaded in Socialync, because a chat cannot pass a video file.
Example result
Illustrative example with made-up posts and numbers. It does not come from a real account, and yours will use your own content.
What the assistant shows before it schedules
Best post: Tuesday how-to Reel, 6,200 views, status good.
Why it worked: the first 3 seconds held 71% of viewers, and it ran 24 seconds.
New post, same idea: "The edit I skip first when a clip feels slow."
Platform: Instagram. Time: Tue 6:30 pm, inside your best window.
Reply yes to schedule.
Limits that shape this recipe
- Post ratings compare each post with your own usual on that platform. A post is not rated when you have fewer than 5 settled posts on that platform to compare with, or when it is under 2 days old.
- YouTube posts carry no rating or engagement total. No post numbers are collected for X.
- Watch time and retention come from Instagram, Facebook and YouTube videos only.
