Your first prompt.

You need a sentence a ten-year-old can understand. Asking “make it simpler” gives you something vague. The agent has no job, no target, and no way to know when it is done.

Say who the agent is, what you want, and what “good” looks like. Three parts. Nothing extra.

You are a friendly editor. Rewrite this sentence so a ten-year-old understands it. Keep it under 20 words.

Sentence: Photosynthesis converts light energy into chemical energy stored in glucose.

Edit the sentence if you like. Run it. Notice which of the three parts did the work.

A three-part prompt you can reuse. Change one part and notice what moves.
