What problem does it solve? Code changes that affect user-facing features often leave documentation stale. This Skill guides the systematic update of an Astro Starlight documentation site so that new tools, configuration options, capabilities, and deployment changes are accurately reflected in both English and Spanish user docs. ## Core Features & Use Cases - Change-to-page mapping: Maps code changes (new MCP tools, config options, transports, security changes) to the specific Starlight doc pages that need updates. - Bilingual EN/ES synchronization: Ensures every English page under site/src/content/docs/ has a mirrored, translated Spanish counterpart under es/. - Starlight conventions enforcement: Covers frontmatter requirements (title, description, chips, datePublished, faq), sidebar registration in astro.config.mjs, and proper use of Starlight components like Aside, Tabs, Steps, and CardGrid. - Use Case: After adding a new MCP tool to the GitLab MCP server, use this Skill to update the tools overview page, add translations, register any new page in the sidebar, and verify the site builds with zero errors. ## Quick Start Update the Starlight user docs to reflect the new configuration option I just added, including the Spanish translations, and verify the site builds successfully.
