The agent partially answered the task by extracting what Yrða does (free Icelandic dictionary, 56K+ entries) and confirming it's free, but could not definitively establish creator/ownership or detailed feature comparisons because the site publishes no About page, creator attribution, or structured documentation. The agent worked around missing identity information by discovering a GitHub repository (ylhyra/icelandic-inflections) and a related learning platform (ylhyra.is), but could not confirm whether ylhyra is the official creator or maintainer of yrda.is.

• ›Step [0] (homepage fetch) returned only minimal metadata: title, description, and theme colors in Icelandic — no structured creator/org attribution, launch date, or feature breakdown. The HTML was truncated and contained no About link or navigation to creator info.
• ›Steps [4], [10], [20] attempted to fetch /about, /faqmini, and word-specific pages (404s or word-definition pages), revealing the site has no dedicated info/about section — the URL scheme treats all paths as dictionary lookups, not documentation.
• ›Steps [16], [23], [24] discovered related GitHub and ylhyra.is resources through web search, not from site navigation. Step [23] (GitHub icelandic-inflections repo) confirmed technical infrastructure but did not establish official ownership. Step [24]'s search found ylhyra.is (a learning platform) but the agent could not verify if ylhyra is the creator of yrda.is or a separate project using similar tools.
• ›The site is entirely in Icelandic with no English documentation, no discoverable creator/license/funding info, and no published feature comparison — agent had to assemble understanding from: (a) meta descriptions, (b) entry count from prior knowledge, (c) guessed navigation paths, and (d) external GitHub/search context.
• ›Web search queries [2–22] consistently returned results for competitors (m.is, Árni Magnússon Institute dictionaries, Icelandic Online) but found zero press releases, blog posts, or news articles about Yrða itself, indicating minimal web presence and no marketing/PR documentation.
