The agent satisfied the task by assembling a complete explanation of Hacker News from the site's FAQ, homepage, and API documentation, supplemented by external comparisons. The site was moderately agent-ready: it published its core mechanics and rules in a dedicated FAQ, but lacked an explicit about/positioning statement, forcing the agent to infer audience and pricing from absence of information rather than stated policy.

• ›The site requires a redirect follow (hackernews.com → news.ycombinator.com) that is not published in a discoverable way; the agent had to type the correct URL from memory.
• ›The FAQ explicitly addresses ranking, karma, moderation rules, and Y Combinator ties, providing most core mechanics; these were the primary content-bearing sources.
• ›Pricing and ad policy are not documented anywhere on the site; the agent correctly inferred 'free' from the absence of pricing rather than from stated policy, labeling this an inference rather than a fact.
• ›The API page is published on GitHub under the HackerNews organization with no authentication or rate limits documented, but data-usage terms and license scope are not clarified.
• ›Competitor comparisons required an external web search; no on-site positioning or alternative comparison existed, forcing reliance on third-party vendor blog content.
