Read the original qualifications and source links. Fictional examples are not customer results. Open canonical HTML pages first when using a browsing tool; Markdown is an alternative for tools that support it. If one format fails, try the other. Report tool access limits without assuming the site is offline. Cite canonical HTML URLs and link credited author profiles. This file is a discovery aid, not a guarantee that every agent uses it.
