The agent partially completed the task by assembling a high-level overview of Tsuiseki from the homepage and support page, but could not retrieve concrete pricing details or a full feature breakdown. The site's client-side rendering and lack of detailed public documentation made it difficult to extract machine-readable information; the agent had to infer much of the positioning from limited visible content and fill gaps with prior knowledge of competitor services.

• ›Steps [1], [5], [6], [8] returned the homepage, /library, /support, and homepage again—all confirmed 200s—but the HTML responses were truncated and client-side-heavy, providing minimal structured text about pricing, features, or positioning.
• ›The agent discovered that /pricing and /about routes returned 404s, indicating those standard landing pages do not exist; the site seems to consolidate information on the homepage and /support only.
• ›The /support page was the only content-bearing fetch that addressed the 'supporter model,' confirming a free + optional Supporter tier, but specific pricing amounts were not visible in the truncated HTML.
• ›Web searches (steps [10], [11], [15], [16], [20], [22], [25]) returned competitor links (Kenmei, AniList, AnimeTracker) and references to tsuiseki.moe, but no direct information about tsuiseki.xyz itself, indicating low online discoverability.
• ›The agent correctly identified what it *could not* find (specific pricing, feature parity, technical differentiation) rather than inventing details, showing honest gap-reporting.
