+**⚠️ CRITICAL FOR AI AGENTS**: These rules must be followed DURING content
+generation, not applied after the fact. Always generate markdown that complies
+with these standards from the start.
+
+## AI Generation Guidelines
+
+### **MANDATORY**: Follow These Rules While Writing
+
+When generating markdown content, you MUST:
+
+1. **Line Length**: Never exceed 80 characters per line
+2. **Blank Lines**: Always add blank lines around headings, lists, and code
+   blocks
+3. **Structure**: Use proper heading hierarchy and document templates
+4. **Formatting**: Apply consistent formatting patterns immediately
+
+### **DO NOT**: Generate content that violates these rules
+
+- ❌ Generate long lines that need breaking
+- ❌ Create content without proper blank line spacing
+- ❌ Use inconsistent formatting patterns
+- ❌ Assume post-processing will fix violations
+
+### **DO**: Generate compliant content from the start
+
+- ✅ Write within 80-character limits
+- ✅ Add blank lines around all structural elements
+- ✅ Use established templates and patterns
+- ✅ Apply formatting standards immediately
