Why this prompt works
- Separates draft from critique so you can steal the structure later.

- Keeps creative writing vocabulary specific instead of buzzwords.
- Locks the audience (fiction writers) before style so tone stays honest.
- Repeats the hard constraint: one conflict.
How to use it in Claude
When fiction writers review output, they should see constraints, evaluation, and edge cases without hunting for it. If the first answer is vague, reply with the constraint again: one conflict. Ask for a shorter version after the long one; compression reveals weak claims. Scenes, voice, character, and narrative craft. Keep that context in the thread when you iterate. Redact client names; keep structure. Slug short-story-advanced is your canonical URL for this brief.
Have Claude list assumptions about creative writing before drafting. Delete any you cannot defend. For short story in creative writing, the failure mode is usually style without substance. This prompt blocks that by design — especially "one conflict". Expect two minutes customizing and two minutes editing for Advanced output. Anthropic models still need your facts for short story; they cannot invent metrics or brand rules. authors and storytellers teams bookmark slug short-story-advanced when constraints, evaluation, and edge cases matters.

- Open Claude and paste the prompt block unchanged.

- Confirm the constraint is still visible: one conflict.
- For creative writing work, paste a rubric and ask for a self-score.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Short Story, 3 short sections, bullet list of recommendations, closing line that states one conflict. Facts you supply appear; nothing invented.
Common mistakes
