microsoft Skill Code ReviewReviews new or changed CODE on aspire.dev for correctness, safety, and adequate test coverage — not documentation prose. USE FOR: reviewing a PR supplied as a number or URL (or the current branch's diff), checking C#/TypeScript/Astro/HTML/CSS changes for bugs, catching correctness/security/data-loss/accessibility regressions, verifying that important scenarios have unit tests, e2e tests (desktop/tablet/mobile), and axe-core accessibility tests. DO NOT USE FOR: validating documentation content or examples (use doc-tester), reviewing a documentation PR for factual accuracy (use doc-pr-reviewer), writing or fixing docs pages (use doc-writer), two-slash TypeScript blocks (use twoslash-validator), or nitpicking style/formatting (ESLint and Prettier own that). INVOKES: git (read-only diff inspection), gh (to resolve and fetch a PR by number or URL), and optionally the repo's existing test commands for verification. FOR SINGLE OPERATIONS: read the diff with git or gh pr diff and apply the relevant language checklist

boom5426 Bundle Nature FigureSubmission-grade Nature/high-impact journal figure workflow for Python or R, plus optional OpenRouter GPT Image 2 manuscript schematic generation when the user explicitly asks for AI-generated graphical abstracts, concept schematics, mechanism diagrams, or paper schematic illustrations. Use whenever the user asks to create, revise, audit, or polish manuscript figures, multi-panel scientific plots, figures4papers-style matplotlib plots, journal-ready SVG/PDF/TIFF outputs, or OpenRouter/API-generated schematic drafts, especially for Nature-family or other high-impact journals. Before plotting or image generation, define the figure's conclusion, evidence logic, export needs, and review risks. For plotting tasks, honor an explicit Python/R choice, otherwise reuse the saved nature-figure backend preference; if no preference exists, ask once whether the user prefers Python or R and save that answer for future calls. For explicit OpenRouter/GPT Image 2 schematic generation, do not ask Python or R; use the AI-schemat
