What problem does it solve? Long prose in GitHub PR descriptions, follow-up comments, and review replies buries the information reviewers actually need. This Skill provides decision rules for folding verbose prose into the right structural format so readers can find conclusions, warnings, and evidence quickly. ## Core Features & Use Cases - Format Selection Guide: Decision tables for choosing between tables, Mermaid diagrams, Alerts, <details> blocks, footnotes, and permalinks based on content type and posting destination (PR body, comment, review reply). - Alert Discipline: Restricts usage to NOTE, IMPORTANT, and WARNING with a 1-2 per body limit, plus rules for what to do when a third candidate appears. - Collapsing Rules: Clear criteria for what goes inside <details> versus what stays visible, and when a separate comment is the better container. - Use Case: When writing a PR description that includes a long test-output log and three caveats, this Skill tells you to keep the conclusion visible, fold the log into a named <details> block, and use at most two Alerts. ## Quick Start Ask the assistant to write or rewrite a GitHub PR description or review reply using the format-github-post skill to structure it with the right formatting elements.
