The agent assembled a coherent explanation of Reaction Finder by combining the homepage (which used structured data to declare price and core features), the Chrome Web Store listing (which described the extension's functionality), and a blog post. However, the site's single-page architecture and heavy reliance on client-side rendering forced the agent to work around missing dedicated pages for pricing, features, and business model details; the agent filled gaps using prior knowledge and web search rather than direct site content.

• ›Step [1] (homepage) returned structured data explicitly stating price ($0 USD) and core features (search, browse, extensions), which formed the foundation of the answer. Steps [3–9] all returned 404s, indicating the site has no traditional information architecture (no /pricing, /about, /features pages).
• ›Step [16] (Chrome Web Store) provided the extension's feature set (sidebar detection, favorites, history tracking, channel blocking, theme awareness) and positioning as a free tool—this was the primary source for how-it-works and differentiation claims.
• ›Step [21] (blog post) was cited as a source and confirmed the platform targets both viewers and creators, but the agent could only retrieve one blog article; broader resource/documentation content was not discoverable.
• ›The agent had to rely on prior knowledge (56% of fetches) and web search (22%) because the site's design does not expose key information through navigable pages. The JavaScript-heavy homepage and extension store page were rendered but did not yield rich extractable text in the trajectory shown.
• ›The site is poorly agent-ready for comprehensive discovery: no FAQ, no explicit competitors comparison, no articulated business model or sustainability explanation, and critical pages returning 404s. The agent compensated by inferring features from the extension and filling gaps with external sources.
