What problem does it solve? Long-form writing projects (over 30,000 words or multi-chapter) often drift off-structure mid-writing, causing inconsistent chapters, unbalanced word counts, and circular dependencies. This Skill turns requirements into a validated, frozen chapter outline that anchors all subsequent writing and rewriting. ## Core Features & Use Cases - Structured Outline Generation: Derives chapter lists with core questions, reader takeaways, and target word counts from a requirements checklist, written to outline.md and chapter-ledger.md. - Deterministic Structure Gate: Validates required sections, unique sequential chapter IDs, word-count allocation against the contract range, and acyclic chapter dependencies via make prepare and the outline-structure-gate.mjs script. - Change Management: Handles post-freeze structural changes through formal change orders with user confirmation before re-freezing. - Use Case: When starting a 50,000-word technical book, use this Skill to convert the intake requirements into a 12-chapter outline, verify the word budget sums correctly, and freeze it before any manuscript writing begins. ## Quick Start Plan and freeze the chapter outline for my long-form book project based on the confirmed requirements checklist.
