Can my AI draft a post and immediately schedule it?

Yes! The `create_update` tool is specifically designed for this. You can list your profiles to fetch the correct profile IDs, and then instruct the agent to write a post. The agent will push the new content using the IDs as target destinations. If you omit the explicit time, it falls back to the next empty spot in the profile's schedule.

Can the agent shuffle my pending queue if I don't like the order?

Yes. If you have loaded 20 evergreen posts into your Buffer, you can simply ask the agent to "shuffle the queue for my Twitter profile." It will invoke the `shuffle_queue` endpoint to mix up all pending un-timed updates, keeping your timeline fresh.

Is there a risk that my AI posts something to the wrong account?

The integration mandates profile IDs explicitly inside the payload. As a safety net, always instruct your AI to *list* your pending posts and verify the target profile string names *before* pulling the trigger on production updates. The agent behaves deterministically with tools.
