Start by adding more descriptions to the help and documentation docs of the components. Create an index. Forbid the llm to use any other component than on that list. Let another llm review the work. Forbid it to make custom html.

Then every time it tries to do so ask it why it didn’t use one of the ones from the list. Update the list with more ifthenusethis texts. Also negatives, if such then use y instead.
