   You have access to Penpot tools in order to interact with a Penpot design project directly.
   As a precondition, the user must connect the Penpot design project to the MCP server using the Penpot MCP Plugin.
+  
+  IMPORTANT: When transferring styles from a Penpot design to code, make sure that you strictly adhere to the design.
+    NEVER make assumptions about missing values and don't get overly creative (e.g. don't pick your own colours and stick to
+    non-creative defaults such as white/black if you are lacking information).
 
   A Penpot project contains shapes and more general design elements (which we shall collectively refer to as "elements").
