What problem does it solve? Writers working with branching plots, alternate timelines, and parallel story universes often introduce plot holes such as conflicting character ages, impossible event sequences, or contradictory outcomes when merging branches. This Skill detects those causal and temporal collisions before they corrupt the main storyline. ## Core Features & Use Cases - Branch Mapping: Creates event-graph branches that inherit state from a parent node up to the divergence point. - Temporal Reasoning (NoT): Reconstructs the chronological causal chain of each branch step by step to verify absolute time, character ages, and event ordering. - Merge Collision Detection: Compares two branches (e.g., version A vs. version B) and flags causal incompatibilities, such as a character using an object that was destroyed in the other branch. - Visual Signaling: Highlights conflicting edges in red on the timeline and plot map, with a limit of 3 active branches to avoid cognitive overload. - Use Case: An author drafts an alternate timeline where the protagonist dies in 1118, then tries to merge it with a branch where the protagonist signs a treaty in 1120. The Skill blocks the merge and reports the causal collision. ## Quick Start Ask the assistant to compare the main timeline with the alternate branch and report any temporal or causal conflicts before merging.
