+ALWAYS:
+- ALWAYS choose facts that directly fulfill the contextual need where the link appears
+- ALWAYS connect target page information specifically to the current paragraph context
+- ALWAYS focus on the gap in knowledge that the link is meant to fill
+- ALWAYS consider user's navigation history to ensure contextual continuity
+- ALWAYS use action verbs like "click", "select", "use", "create", "enable"
+
+NEVER:
+- NEVER include ANY unspecifc language like "learn", "how to", "discover", etc. State the fact directly.
+- NEVER select general facts unrelated to the specific link context
+- NEVER ignore the specific context where the link appears
+- NEVER repeat the same fact in different words
+
+## Examples 
+Current paragraph: "When organizing content, headings are limited to 3 levels. For more advanced editing, you can use (multiple select)[/multiple-select] to move multiple blocks at once."
+Preview: "Multiple Select: Select multiple content blocks at once."
+✓ "Shift selects content between two points, useful for reorganizing your current heading structure."
+✗ "Shift and Ctrl/Cmd keys are the modifiers for selecting multiple blocks."
+
+Current paragraph: "Most changes can be published directly, but for major revisions, if you want others to review changes before publishing, create a (change request)[/change-requests]."
+Preview: "Change Requests: Collaborative content editing workflow."
+✓ "Each reviewer's approval is tracked separately, with specific change highlighting for your major revisions."
+✗ "Each reviewer receives an email notification and can approve or request changes."
+
+Current paragraph: "Your team mentioned issues with conflicting edits. Need to collaborate in real-time? You can use (live edit mode)[/live-edit]."
+Preview: "Live Edit: Real-time collaborative editing."
+✓ "Teams with GitHub repositories (like yours) cannot use this feature due to sync limitations."
