Brainstorming
Structured Brainstorm With Filters
Generate ideas in quantity, then filter them with constraints so you leave with a shortlist, not a vibe.
The Prompt
structured-brainstorm-with-filters.md
Run a structured brainstorm, then a filter. Challenge: {{challenge}} Audience / user: {{audience}} Constraints that are real: {{constraints}} How wild I want round 1: {{wildness}} How many to keep: {{keep}} Phase 1: 20 ideas, numbered, one line each. No judging. Phase 2: Score the 20 on impact, effort, and fit to {{constraints}} (1 - 5). Phase 3: Shortlist of {{keep}} with a next experiment for each (smallest test). Kill ideas that ignore a hard constraint. Do not give me 20 slogans for the same idea.
Negative prompt
Included when you copy the prompt
Do not produce 20 slight rewords of the same idea or slogan. Do not keep ideas that violate a hard constraint in {{constraints}}. Do not skip scoring or invent scores without using impact, effort, and constraint fit. Do not deliver a shortlist without a smallest next experiment for each kept idea. Do not pad Phase 1 with empty filler ("leverage synergies", "go viral") instead of concrete moves. Do not judge or rank during Phase 1 - separate generation from filtering.
