Most prompts do not fail because the model is dumb. They fail because the prompt is vague — it leaves the model to guess the role, the format, and the edge cases, and it guesses differently every time. The fix is not a magic phrase. It is treating a prompt like a reusable spec , not a one-off question. Here is the practical version. 1. Stop asking questions. Start writing specs. Write a tweet about our launch is a question. A spec tells the model who
