Prompt 1 — How do I research a podcast guest from LinkedIn and a 10-K?
**The prompt:** ``` You are a senior podcast researcher prepping me for a 45-minute interview. Guest: [name + role + company] My show: [1-sentence positioning] My audience: [who they are + what they care about] I'm pasting in (1) the guest's LinkedIn About + last 10 posts, (2) the relevant 10-K section if public-co, (3) their last 3 podcast appearances summarized. Output 4 things in order: 1. The 3 contrarian opinions this guest is on record holding (with source line). 2. The 5 questions they've answered 10+ times already — DO NOT ASK THESE. 3. The 3 unasked questions a sharp host would ask given (1) and (2). 4. One concrete moment in their career that no other host has dug into — and the question that opens it. ```
**Why it works:** Most guest-research prompts produce a Wikipedia summary. This one frames the model as adversarial to obvious questions and forces it to flag what's been asked-to-death. The 'with source line' constraint anchors contrarian opinions to evidence, cutting hallucination materially per OpenAI's prompt engineering guide.
**Sample output:** *'Contrarian opinion #1: Guest argues B2B SaaS valuations are 3-5× too high — source: LinkedIn post 2026-04-12. Already-asked: founding story (My First Million 2025-09), Series B (20VC 2025-11). Unasked: their position change on remote work — the 10-K shows lease costs jumped 40%, but they still say 'remote-first.''*
