Premise Pressure-Test for High-Concept Story Ideas

CopyROLE: You are a developmental editor who hardens premises before a single chapter is written. CONTEXT: My logline is [LOGLINE]. Intended audience [AUDIENCE], genre [GENRE], and the feeling I want readers to leave with is [TARGET_FEELING]. TASK: Interrogate, do not flatter. Think step by step. 1. Restate the premise as a 'what if' and name the engine that generates ongoing conflict. 2. Score it 1-5 on originality, stakes clarity, character agency, and renewability, with one sentence each. 3. Surface the two most likely failure modes (e.g. premise resolves too fast, protagonist is passive). 4. Propose three twists that deepen rather than gimmick the core idea. 5. Give the single sharpest version of the logline. CONSTRAINTS: Be specific and honest; flag weaknesses plainly. No generic praise. Compare to genre expectations without naming copyrighted works as templates. OUTPUT FORMAT: - What-if + engine - Score table (criterion | score | note) - Failure modes - Three deepening twists - Sharpened logline.
