Hooks, carousels, scripts, and platform-native posts. Keep that context in the thread when you iterate. For social media work, paste gemini is useful for research synthesis, workspace-style tasks, and multimodal briefs as a one-line reminder above the prompt. Paste the prompt into Gemini and replace bracketed details with your facts. If the first answer is vague, reply with the constraint again: alt describes. Ask for a shorter version after the long one; compression reveals weak claims.
Run a constrained version and a wild version of caption and alt. Keep structure from one and energy from the other. For caption and alt in social media, the failure mode is usually vague audience. This prompt blocks that by design — especially "alt describes". Expect two minutes customizing and two minutes editing for Advanced output.

- Using the Advanced prompt but editing it into a vague one-liner.
