System Prompts (Notes)
Any plain text inserted between the summary and the links acts as an implicit system prompt. AI agents will read this text as direct instructions on how to interpret, cite, or write code based on your data.
Annotated Links
URLs are formatted as standard Markdown list items. The text inside the brackets should be descriptive. You can append a colon and a short description after the link to give the AI context before it visits the URL.
