Implementation tips
- 1
Ask for three distinct plot directions — conservative, subversive, and experimental — rather than one 'best' plot: creative ideation produces more value through option generation than single-path exploration.
- 2
Use the model to stress-test your plot: describe your story and ask it to find plot holes, pacing issues, and character motivations that don't track — this adversarial pass catches problems before you've written 50,000 words.
- 3
Generate character relationship maps as a structured JSON object (characters as nodes, relationships as edges with types) before writing — this external memory prevents the model from contradicting established relationships across long documents.
