Writing posts with the agent
Say what you want. The agent writes in your voice, from your material, and keeps drafts where you can find them.
Write to the agent the way you would to a colleague: “three posts about the new opening hours, warm tone, for Facebook and Instagram”. It writes, saves each as a draft under Posts, and shows them in the conversation. Every draft has a number (#7); use it to refer to a post in later requests.
Per-network wording
One idea can be worded differently for each network. Ask for it and the draft carries a variant per network: 280 characters for X, a fuller version for LinkedIn, a caption for Instagram. Where a network is shorter than what you wrote, the agent tells you rather than cutting silently.
Threads and first comments
X posts can carry a thread: continuation posts published as replies. Facebook and LinkedIn can carry a first comment, useful for links you do not want in the post itself. Instagram and TikTok have neither.
Editing
Tell the agent what to change (“shorter, and drop the hashtag”) or edit the text inline under Posts. Editing keeps the same draft and number; nothing is duplicated. Swap or add a picture the same way.
Not repeating yourself
The agent sees how your recent posts opened and closed and which hashtags you have leaned on, and avoids them. If everything you post begins “Did you know”, it is because you asked; the agent will not.
