The agent successfully understood CheckWhenDone's core offering by extracting information directly from the homepage and a secondary page (/print), then filled gaps with prior knowledge about habit tracking and indie product patterns. The site is minimally navigable—standard discovery pages (pricing, about, FAQ) return 404s, forcing the agent to rely heavily on what it could infer from the homepage UI and prior knowledge rather than explicit documentation.

• ›Step [1] (homepage) was the only substantive content source; it contained enough UI text and copy to establish the product's purpose (printable habit tracking), philosophy (paper-based repetition), and basic feature set (schedule vs. simple mode, customization, URL-based sharing). Step [6] (/print) confirmed the tool exists but returned a similar template structure with no additional clarifying content.
• ›The agent attempted standard discovery routes (pricing, about, FAQ) in steps [3–5], all of which returned 404s. This forced the agent to assemble pricing information ('Completely free') and positioning ('indie product') from homepage inference and prior knowledge rather than from explicit site content.
• ›The site's agent-readiness is low: no structured data (schema.org, JSON-LD), no dedicated documentation pages, no creator bio, no FAQ, and minimal metadata. The agent succeeded because it could parse the homepage's plain-language pitch and fill gaps with reasonable assumptions about printable habit trackers, but a user or agent with no prior context would find the site cryptic. The 'Advanced settings' feature is mentioned but never explained.
