What problem does it solve? When editing an existing document, agents and writers tend to fix only the flagged paragraph, append new sections at the end, or re-add content that a previous review deliberately removed. This Skill inserts a mandatory pre-edit checkpoint: read the whole document skeleton, map the impact area, and pass three gate questions before changing a single word. ## Core Features & Use Cases - Three-Step Hard Constraint: Read the whole piece, list the impact area (what you will touch plus related existing logic), then answer three gate questions about history, risk, and skeleton integrity. - Skeleton-First Rule: For new or heavily revised documents, establish the outline (one opinion sentence per section) before filling content, and re-scan the skeleton after any section change. - Pre-Edit Report Template: Produces a structured report covering what was read, the impact list, the three gate answers, and a final decision of edit, do-not-edit, or redesign at the skeleton level. - Use Case: A reviewer flags one paragraph in your design document. Instead of patching that paragraph, you first read the full skeleton, discover the paragraph's argument is actually supported in a later section, and decide to move evidence rather than rewrite. ## Quick Start Ask the agent to revise a section of an existing document and require it to run the pre-edit reading report before making any changes.
