Skills (5)
AI crawler access check
ai-crawler-checkReads a site's robots.txt and reports, for 18 AI crawlers (GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, Claude-SearchBot, PerplexityBot, Google-Extended and others), whether each may visit the homepage, whether it is named directly, and whether it is used for AI search, live answers or training. Includes a ready-made robots.txt policy.
llms.txt validator
llms-txt-checkFetches a site's /llms.txt, validates it against the llmstxt.org format (title, summary, sections, link format, size), tests a sample of its links for 404s and reports whether /llms-full.txt exists.
llms.txt draft generator
llms-txt-draftBuilds a first-draft llms.txt for a site from its homepage title, description, links and sitemap, grouped into sections. The draft needs a human edit (link descriptions) before publishing.
Website findability audit (SEO + AEO)
page-auditMeasures one web page for search-engine (SEO) and answer-engine (AEO) readiness: titles, meta, indexability, structured data, question-style content, page speed and more. Returns 0–100 scores, every check result, the free prioritised fixes and a shareable report link. Takes 10–40 seconds. Free limit: 5 new audits per day per caller; a page audited in the last 24 hours is returned from cache.
Search snippet length check
snippet-checkReads a page's title and meta description and measures their rendered width in pixels against the points where Google truncates them on desktop (about 580 px for titles and 1000 px for descriptions).
