In the pack: ChatGPT, Claude & Gemini Prompts for Writers and Authors
Magic or Technology System Limits and Costs
Prompt
How my system works, as I've written it: {{SYSTEM_RULES}}
How the protagonist uses it at the climax: {{CLIMAX_USE}}
Other key uses earlier in the book: {{EARLIER_USES}}
Check the system:
1. Restate the rules as a short numbered list, so I can confirm you've understood them.
2. Costs and limits: what does using it cost (physically, socially, morally, financially)? If there's no meaningful cost, say what problems that creates for tension.
3. Loopholes: list ways a clever character could exploit these rules to solve the plot early. For each, ask why nobody does.
4. Climax test: is the climax use set up earlier, and does it follow the rules? If it breaks a rule, has the book earned the exception?
5. Consistency: compare the earlier uses against the rules and flag any contradiction.
6. Wider effects: name two ways this system would change ordinary society that my summary doesn't mention.
Keep suggestions as questions or options. The system is mine; don't redesign it.
