The agent successfully gathered and synthesized information about rivers.plasticbank.com by fetching the homepage and several key content pages (research notes, key facts, riverine emissions explainer, and FAQ), supplemented by web searches to find alternatives and context. The site is reasonably navigable for a static educational resource—core pages are discoverable and content-rich—but the interactive map features themselves could not be fully inspected, and pricing/business model information was absent from the rivers subdomain (requiring cross-reference to the main Plastic Bank site). The agent delivered a complete, well-sourced explanation suitable for teaching someone else about the platform.

• ›Steps [1] and [2] returned the homepage with a clear value proposition in the title/meta description ('1,656 rivers carry 80% of ocean plastic'), establishing the core message immediately.
• ›Steps [8], [9], [10], and [13] returned substantive content pages (research notes, key facts, topic explainers, FAQ) that the agent directly cited in its Sources section, confirming these were content-bearing rather than routing steps. Each provided distinct pieces: the research-notes page clarified why the 'top 10 rivers' narrative is outdated, the key-facts page delivered statistics, the topics page defined riverine plastic emissions, and the FAQ answered common questions.
• ›The site publishes most answers in a fetchable, readable form (static HTML pages with clear structure), but the interactive map itself is JavaScript-rendered and not directly inspectable—the agent could not describe what interactions the map supports (filtering, search, regional drill-down, data export), only that it exists. This is a gap in how the site makes its interactive features discoverable to non-human agents.
• ›Pricing and business model information for rivers.plasticbank.com is absent from the rivers subdomain—the agent correctly noted the site is 'completely free' but had to rely on context (that it's a research resource) rather than explicit pricing pages. The main Plastic Bank site hosts pricing for the company's social-recycling product, but rivers appears to be a separate educational initiative.
• ›The agent used web search (steps [6], [7], [11], [12], [14], [15], [16]) primarily to discover comparisons and context (Ocean Cleanup, Investable Oceans alternatives) that are not linked from or mentioned on rivers.plasticbank.com itself. The site is self-contained and does not position itself against competitors, requiring external search to fulfill the 'how it's different' part of the task.
• ›The distinction between rivers.plasticbank.com (research/education) and the main Plastic Bank platform (social enterprise collection program) is not made explicit on the rivers site itself—the agent had to infer this from context and cross-site navigation, highlighting a potential UX gap for first-time visitors.
