The agent successfully assembled a comprehensive explanation of GrowthBook by pivoting away from the docs site (which is JavaScript-heavy and returned truncated responses) to the marketing website, where it retrieved pricing and product positioning details. However, it relied heavily on prior knowledge and web search results rather than actual content from docs.growthbook.io, making the docs site itself effectively opaque to the agent despite task completion.

• ›Steps [1], [3], [6] returned 200 responses from docs.growthbook.io but only HTML scaffolding was visible; the actual content was JavaScript-rendered and not fetchable, forcing the agent to abandon the docs site entirely.
• ›Steps [8] and [12] (www.growthbook.io homepage and pricing page) were the only content-bearing sources that actually delivered usable information about what GrowthBook does, pricing tiers, and differentiation.
• ›The agent filled critical gaps using prior knowledge (38% of fetches) and web search results that linked to third-party comparison pages and the marketing site, not the docs. The docs site appears to exist primarily as a JS-rendered SPA with no server-side content delivery, making it agent-hostile.
• ›The final response cites GrowthBook's own marketing website and blog as sources, but explicitly calls out that the docs site content was inaccessible ('docs.growthbook.io site loads primarily through JavaScript, making it hard to scrape full content').
• ›The task required discovery and evaluation (what the product does, pricing, alternatives) — all of which was answered from the marketing site and prior knowledge, not from the documentation site that was the starting domain.
