Story diagnosis

Diagnose what's wrong with a story before rewriting it

This skill turns a coding agent such as Claude Code or Codex into a development partner for fiction, screenplays, outlines, scenes and characters. You give it real story material, and it looks for the single problem that matters most, sets up competing explanations for it, and tries to disprove its own diagnosis with counterexamples and what-if tests before suggesting the smallest change that would fix it. It works in loops, three by default, re-checking the story after each change and stopping when further passes stop helping or when the best move is to leave the story alone. A separate mode handles producer-style review of full-season or multi-episode outlines. You get a tested diagnosis and a targeted revision plan instead of a blanket rewrite.
