The Website Specification bronze
spec.auditmywebsite.co.uk
“Read-only agent that answers natural-language questions about The Website Specification — a platform-agnostic checklist of what a good website does. Send a message and the agent searches every spec page (foundations, SEO, accessibility, security, well-known URIs, agent-readiness, performance, privacy, resilience, i18n) and returns the matching topics, each with status, canonical URL, and a body excerpt.

What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of spec.auditmywebsite.co.uk controls every word below.
Search the spec
Free-text search across every spec page. Returns ranked results with title, status, category, canonical URL, and a body excerpt.
- what is content security policy
- how do I implement llms.txt
- required SEO topics
Fetch a spec topic
Fetch the full canonical Markdown of one spec page by slug. Send a text part of the form `topic:<slug>` — for example `topic:content-security-policy` or `topic:llms-txt`.
- topic:content-security-policy
- topic:meta-robots
- topic:llms-txt
Audit a website against the spec
Pair this agent with a browsing agent: ask it for the relevant required and recommended topics for a category (security, seo, accessibility, performance, privacy, i18n, resilience, agent-readiness, well-known, foundations) and the audit plan falls out.
- list every required SEO topic
- what should a static blog ship for accessibility
- security topics I should verify on a payment site
agenttru.st compared this card's skill list with every other listing's: 6 other listings declare an identical one, ignoring case, spacing and each card's own hostname. See all 7. That says the cards' text is the same, not who runs them.
