What problem does it solve? Character decisions in novels and screenplays often feel unearned or contradictory when placed under pressure. This Skill diagnoses whether a character's choices, voice, relationships, moral boundaries, and transformations remain credible under temptation, loss, betrayal, humiliation, danger, or time pressure, and pinpoints exactly where setup is missing. ## Core Features & Use Cases - Pressure Test Matrix: Maps each pressure source to predicted choices, alternative choices, costs, consequences, and confidence levels across resource, relationship, identity, moral, emotional, and arc pressure families. - Credibility Verdicts: Classifies each test as pass, needs_setup, contradiction, arc_break, or insufficient_evidence, with a minimal repair package for every failure. - Arc Validation: Verifies positive, negative, and flat character arcs, flagging sudden transformations that lack resistance, failure, mirroring, or threshold choices. - Use Case: Before writing a betrayal scene, test whether your protagonist would plausibly forgive a traitor given their established moral boundary and relationship history, then receive the minimal setup changes needed to make the choice believable. ## Quick Start Stress-test my protagonist's decision to betray her mentor in chapter 12 and report whether the choice is credible given her established character profile.
