Make Your Idea Fight to Survive: The Free Claude Idea Evolution Prompt

Run an Idea Fight on my idea. Your job is NOT to agree with me. Claude tends to like whatever idea it is shown, so for this whole run you are a referee, not a fan. No praise, no "great idea", no softening. If an idea would die in the real world, say so plainly.
GENERATION 1: WRITE 10 VERSIONS
Write 10 genuinely different versions of my idea. Change the real bones each time: who it's for, what problem it solves, how it makes money or wins attention, and how it reaches people. No near-copies with a new name. Give each one a short name and a one-line pitch.
THE PREDATORS
Three predators attack every version, each in role:
- CUSTOMER: "Would I actually pay for this or care about it? What would I use instead, or do I just ignore it?"
- COMPETITOR: "I already exist in this space. How do I copy or crush this in a month?"
- INVESTOR: "Does this make money, and can it grow past the first 100 people? Where do the numbers break?"
Each predator names the ONE most likely reason this version dies in the real world, in one plain sentence, and gives a survival score from 1 to 10 (10 = this attack barely hurts it). Be specific to this version. A generic risk like "competition is tough" doesn't count. Don't invent facts, numbers or companies; if you aren't sure something is true, say "assumption:" in front of it.
SCOREBOARD
After every generation show a short table: rank | name | customer | competitor | investor | total (out of 30) | how it dies (or "survives"). Lowest totals at the bottom.
SELECTION AND BREEDING
- Kill every version except the top 3. Add each killed one to THE GRAVEYARD with its name and the one line that killed it.
- Breed the next generation: write 10 new versions by mixing the best parts of the 3 survivors (for example the customer of one, the money model of another, the reach of the third). At least 2 of the 10 must also fix the exact attack that hurt the survivors most. Keep the 3 survivors in the next round so they have to beat their children.
- Run the predators and the scoreboard again on all 13.
Repeat for 5 generations in total (or the number I give below). Keep each round short: the scoreboard, the graveyard additions and one line on what changed. Never pass a weak idea through just because it's mine.
FINAL RESULT
1. THE SURVIVOR: the one idea still standing, its pitch in 2 sentences, and its scores.
2. WHY IT SURVIVED: the 3 attacks it beat and how.
3. ITS BIGGEST WOUND: the attack it still hasn't fully beaten.
4. THE GRAVEYARD: every dead version, one line each on why it died.
5. TEST THIS WEEK: the single riskiest assumption the survivor depends on, and one cheap test I can run in the next 7 days with real people to check it (what to do, who to ask, and what result would mean "keep going" or "stop").
Generations: 5
