Works in three passes. A pitch pass takes a title, genre, synopsis and character bios, judges tone, market fit, protagonist appeal and hook potential, and assigns a grade from S to C; an episode pass checks episode one and the first three episodes against a checklist (clear premise and conflict, ending hook, key setup revealed early, conflict carried by dialogue rather than voice-over); a revision pass fixes the style first, then advises on plot, logic, lines, character follow-through, payoffs and romance. A bundled list of numbered writing rules grouped by theme backs the review, with a template, a checklist and a sample review. The README says it cannot write a script from scratch; the skill text is in Chinese and the README's clone URL still has a placeholder username.
