1Seo Reviewseo-review is a focused SEO audit skill built for the 33 JavaScript Concepts documentation project. It evaluates concept pages before publish, after major content updates, or during periodic audits when pages underperform in search. The skill checks on-page elements that help JavaScript developers find answers to queries like what is a concept in JavaScript and how does a concept work, optimizing for featured snippets and ranking potential. Developers reach for seo-review when launching or refreshing educational JS content and need a repeatable checklist instead of ad-hoc metadata edits. It targets documentation publishers who care about search visibility for individual concept articles rather than whole-site infrastructure audits.616installs2Test Writertest-writer is a skill in leonardomso/33-js-concepts that produces Vitest tests for every code example on a JavaScript concept documentation page. It follows project conventions, references source line numbers, and covers edge cases, async flows, and DOM APIs tied to the 33 JS concepts learning exercises. Developers invoke it after adding or updating concept pages, before publishing, or whenever documentation accuracy needs executable verification. The output is runnable Vitest test files that turn static snippets into CI-ready checks instead of manual copy-paste validation.330installs3Fact Checkfact-check is the JavaScript Fact Checker skill from leonardomso/33-js-concepts that prevents misinformation in concept documentation pages. It verifies code examples run correctly, checks claims against MDN and ECMAScript compliance, and validates external resource references before publication. Use it before publishing a new concept page, after significant edits, when reviewing community contributions, when updating pages with new JavaScript features, or during periodic accuracy audits. The skill protects against incorrect API behavior descriptions, outdated syntax examples, and misleading comparisons across the 33 JavaScript Concepts project. Developers and technical writers reach for fact-check when tutorial accuracy matters for education SEO and when incorrect JavaScript claims could mislead thousands of learners reading the curriculum.315installs4Concept Workflowconcept-workflow is an end-to-end workflow skill in the leonardomso/33-js-concepts repository that creates complete, high-quality JavaScript concept pages from scratch. It orchestrates five specialized skills in order: Resource Curation for learning sources, Concept Writing for the documentation page, Test Writing for code example tests, Fact Checking for technical accuracy, and SEO Review for search visibility. Developers reach for concept-workflow when authoring a new concept page for the 33-js-concepts curriculum during upskilling content work, open-source documentation contributions, or interview-prep material production. Instead of running each sub-skill manually, agents follow one documented sequence that keeps research, writing, testing, verification, and SEO aligned. Use it when a concept page must ship with verified examples, linked resources, and search-optimized structure rather than a single draft pass.305installs5Resource Curatorresource-curator is a leonardomso/33-js-concepts skill for finding, evaluating, adding, and maintaining high-quality external resources on JavaScript concept documentation pages. It covers sourcing authoritative articles, videos, and courses, reviewing community contributions, and auditing existing links for breakage or outdated content. Developers and doc maintainers reach for it when creating a new concept page, refreshing stale references, or running periodic link maintenance across the 33 JavaScript concepts catalog. The workflow emphasizes citation-quality sources that keep concept explanations accurate rather than generating tutorial copy from scratch. Use it during build-phase documentation work when external references must stay trustworthy and current.299installs6Write ConceptGuides authors to write polished JavaScript concept articles with consistent structure, tested code examples, and precise explanations aligned with the 33-js-concepts pedagogical format.288installs
