technical-seo-audit
Comprehensive technical SEO audit skill that analyses crawl data to identify issues, prioritise actions by business impact, and produce a detailed report plus actionable spreadsheet. Use this skill whenever the user wants to: run a technical SEO audit, analyse a website's technical health, review crawl data from Screaming Frog or Sitebulb, crawl a site via API (Firecrawl or similar), find indexability or crawlability issues, check Core Web Vitals, audit structured data or schema markup, detect cannibalisation or thin content, review redirect chains, find orphan pages, assess site architecture, or produce a prioritised list of SEO fixes.

ide-index-mcp
Guide for using JetBrains IDE Index MCP tools for code navigation, refactoring, and analysis. TRIGGER: When ANY of these MCP tools are available in the current session: ide_find_references, ide_find_definition, ide_find_class, ide_find_file, ide_search_text, ide_diagnostics, ide_index_status, ide_sync_files, ide_refactor_rename, ide_move_file, ide_type_hierarchy, ide_call_hierarchy, ide_find_implementations, ide_find_symbol, ide_find_super_methods, ide_file_structure, ide_refactor_safe_delete, ide_reformat_code, ide_build_project, ide_read_file, ide_get_active_file, ide_open_file.
