What problem does it solve? Adding a blog post to this Astro site requires more than writing Markdown: the MDX frontmatter must follow strict conventions, and derived artifacts like blogData.ts, OG images, RSS entries, and JSON-LD metadata must stay in sync. This Skill encodes the entire workflow so nothing is missed. ## Core Features & Use Cases - MDX Post Creation: Generates a correctly structured MDX file under src/content/blog/{en,ru}/ with all required frontmatter fields (title, date, publishedAt, summary, tags, category). - Data Regeneration: Runs npm run generate:all to rebuild blogData.ts and per-post OG images, then npm run validate:blog to confirm MDX and generated data stay in sync. - Bilingual Support: Enforces matching slugs across English and Russian variants so hreflang pairs resolve correctly. - Use Case: You want to publish a post about cutting mobile CI build times. The Skill creates the MDX file with valid frontmatter, regenerates the static data and OG image, validates sync, and reminds you to verify RSS, sitemap, and JSON-LD output. ## Quick Start Create a new blog post titled "Cutting Mobile CI Build Times" with the appropriate frontmatter, then regenerate the blog data and OG image.
