What problem does it solve? Design docs, RFCs, and tech specs accumulate bloat: restated decisions, meta-commentary, and inline config dumps that bury the actual reasoning. This Skill trims a document to its one-sentence aim while protecting every distinct rationale, caveat, and justification. ## Core Features & Use Cases - Risk-tiered cutting: Classifies every candidate cut as clean redundancy (apply), framing-only (flag for the author), or rationale-touching (discard), so no "why" is ever lost. - Structure preservation: On published or reviewed docs, uses exact verbatim old-to-new edits with unique-match find/replace and invariant checks so review-comment anchors, intra-doc links, tables, and headings survive the edit. - Detail relocation: Pushes exact values, configs, and tables into an appendix or linked runbook, keeping prose at the what-and-why level. - Use Case: You have a 12-page architecture proposal with reviewer comments anchored throughout. Ask the Skill to tighten it for final review; it cuts restatement and boilerplate, moves config tables to an appendix, and leaves every comment anchor intact. ## Quick Start Tighten this design doc for review, keep all the rationale, and don't break any of the existing comment anchors or section links.
