Skill UI

This skill covers core SEO principles like E-E-A-T, Core Web Vitals, and technical foundations. It explains how search engines evaluate content quality, page experience, and trustworthiness. It guides users on creating sustainable search visibility through high-quality content, proper technical setup, and ethical AI usage, rather than relying on shortcuts.

This skill analyzes keyword usage in content, calculates density, and suggests semantic variations and LSI keywords to prevent over-optimization. It helps optimize content for search engines by identifying primary and secondary keywords, mapping entities, and ensuring natural language patterns. Use it for SEO workflows and content optimization tasks.

Analyzes content hierarchy, header tags, and internal linking strategies to improve search engine visibility. Suggests schema markup and logical information architecture for better SEO performance and user experience.

This skill provides comprehensive diagnosis and optimization for agent skill libraries. By analyzing historical session transcripts from platforms like Claude Code and Codex, alongside static skill file checks, it scores each skill across 8 dimensions. It identifies issues such as low trigger rates, poor post-invocation user reaction, and incomplete workflow execution, generating a prioritized report (P0/P1/P2) to significantly improve the agent's overall performance and reliability.

Optimize Apache Spark jobs with partitioning, caching, shuffle optimization, and memory tuning. Use when improving Spark performance, debugging slow jobs, or scaling data processing pipelines.

Diagnose slow SQL queries using execution plans, preserve results, and validate indexing or query modifications against representative data. This skill helps debug performance issues, design efficient schemas, reduce database load, and improve application scalability for growing datasets.

This skill provides comprehensive guidelines for optimizing Postgres database performance and security.
