-### Mathematical Expressions
-Agent Zero supports KaTeX for beautiful mathematical typesetting:
-
-* **Inline Math:** Use single dollars `$...$` for inline expressions
-  - Example: Type `The area of a circle is $A = πr^2$`
-  - Renders as: The area of a circle is $A = πr^2$
-
-* **Display Math:** Use double dollars `$$...$$` for centered display equations
-  - Example: Type `$$F = G\frac{m_1m_2}{r^2}$$`
-  - Renders as a centered equation
-
