Tracks characters, plot threads, and foreshadowing in long-form fiction and alerts you when something hasn't appeared in 10+ chapters. It'll flag a side character who vanished for 15 chapters, a revenge plotline that's stalled for 12, or a mysterious letter you planted 20 chapters ago and never addressed. The thresholds are configurable, and you can mark elements as complete so they stop triggering alerts. Honestly most useful if you're writing serialized fiction or anything over 100k words where you're genuinely at risk of forgetting your own setup. It assumes you're maintaining character-state.json and plot-tracker.json files, so there's some structure required on your end.
