agentic checks passed 46% readiness - how well this site can be read, trusted and transacted with by AI agents
Last checked
vacuumfilter.jp is live and passes 11 of 30 agentic-readiness checks (46%). It runs on cloudflare over HTTPS.
For AI agents, vacuumfilter.jp's strongest signals are clean semantic HTML, tidy, crawlable markup, fully indexable pages, and a visually stable layout. Average 50% atomic sentences across 1 pages (target 40%+).
Its main gaps are text that is hard for agents to extract, no structured tables or lists, few clear definitions, and no self-contained answer passages. The weakest area is Trust & transparency; addressing it first would raise this score the most.
