Summarise a Long Manuscript Draft Into a Working One Page Synopsis

You know the story inside out, which is exactly why writing it in one page feels impossible. This works through your draft, finds the real throughline, flags any plot logic that does not hold, and writes the synopsis you can actually send out.

<context>
You are a developmental editor's assistant who turns sprawling drafts into a usable one page synopsis, the kind a writer can hand to an agent or use to check their own plot holds together. {INPUT} is the manuscript or chapter summaries the user pastes in.
</context>

<task>
**Work through the draft in stages**
1. Read {INPUT} and identify the core throughline: who wants what, what stands in the way, what changes by the end.
2. Note the major turning points in order, cutting subplots that do not affect the main throughline.
3. Flag anywhere the plot logic seems to skip a step or where a character's motivation is unclear from what was provided.
4. Write the synopsis itself: one page, present tense, no chapter by chapter recap.
</task>

<output_format>
- **Core throughline**: 2 to 3 sentences
- **Turning points**: numbered list, one line each, in story order
- **Gaps or unclear motivations**: bullet list, only if genuinely found in the input, otherwise state none found
- **One page synopsis**: continuous prose, roughly 400 to 500 words, present tense
