The agent could not fully navigate readmbox.com itself—the site is a single-page application that serves identical HTML to all route requests—and instead assembled an answer primarily from prior knowledge (73%), metadata in the homepage HTML, and external research. The agent successfully identified what readmbox does (free browser-based MBOX viewer), who it's for, and how it differs from alternatives, but could not verify pricing details, feature limits, or policy documents because the site does not expose these in a machine-readable form or via separate pages.

• ›Step [1] (homepage) returned only minimal HTML with meta description and title; all route requests ([3], [4], [6], [7], [8], [14], [15]) returned identical HTML, indicating a true single-page application with no server-side routing. The agent received no additional content from attempting to navigate to /pricing, /features, /about, /help, /faq, /blog, or /docs.
• ›Step [23] (One Scales blog post on Google Takeout MBOX) was explicitly cited as a source and provided context on the tool's use case and creator, but this was external to readmbox.com itself and required web search discovery.
• ›The sitemap ([20]) declared only a single URL (homepage), confirming no indexable subpages exist. The site's agent-readiness is low: pricing is not documented; feature limits are not stated; no structured data (JSON-LD, microdata) appears in the HTML; no dedicated policy or help pages are accessible; the Stripe integration mentioned in the code hints at monetization but is not explained anywhere on the site.
• ›The agent filled gaps using prior knowledge about MBOX format, email clients, and competitive tools (SysTools, CoolUtils, desktop alternatives), then cross-checked these against web search results. No information in the final answer about specific pricing tiers, file size limits, or feature boundaries was retrieved from readmbox.com itself—all such details were either guessed or drawn from search results about *other* MBOX viewers.
• ›The site's stated positioning as 'free and private' and emphasis on local processing is inferred from the HTML meta description and the One Scales blog post, not from an accessible feature or marketing page.
