What you will get back
01Situation
2–3 sentences. Who is acting, for whom, and under what pressure. State the stakes concretely ("hundreds of emails daily", "risk of capital loss"). May open "You are an experienced <role>…" when the task is communicative.
02Task
1–2 sentences opening on an imperative verb. When the task is an audit or a review, enumerate the sub-areas — 4 to 6 named failure classes.
03Objective
The deliverable spec, as a numbered checklist. Length caps, required components, severity tiers if it is a review, and a "for every X provide Y" rule. Every concrete item from the ideal-output description reappears here.
04Knowledge
Tone constraints, domain conventions, the persona ("Act as a Senior …"), the standards to adhere to (PEP 8, one-stop metadata), and the fail-safes for when the model lacks information.
