-### Context structure
+### Use of XML
 
-The context is formatted as XML.
+The context and actions are formatted as XML.
+For the context this adds clear rules for escaping.
+This is usefull in case a previous context is embedded.
+
+The response starts with freeform reasoning followed by XML formatted actions.
+In case the LLM makes a mistake it can start over.
+Only the last XML block is evaluated.
+
+XML is verbose by nature.
+To avoid overflowing the context window, it should only be used where it adds value.
+Directory listings, for instance, are formatted in the well known ls command format.
+
+Parameters for actions can be passed as attributes or as child elements.
+This allows the LLM to pass multiple volumes or environment variables in a clear way.
+It also simplifies escaping of command line arguments.
+
+Action results are added in the context as text nodes after the last parameter.

 John did not specify an exact time. I'll suggest 9am. He also did not specify how to be reminded. I'll ask but if he doesn't respond I'll assume a text message on standard output is fine. I'll write down this task in a file so I can keep it in context. I can write simple files with busybox:latest and echo but I will need to use sh -c to do the redirect.
