Is there a way to limit generation length in select?

[afg1]

I'm having some trouble with a select that is for some reason exceeding the context window of the model. I'm using select to choose citations for a summary like this:

lm +=(
  " ["
  + select(pmcids, name="references", recurse=True)
  + "]"
)

where pmcids is a list of ~15 strings like "PMC123456", with " " and "," to allow multiple references to be selected. I've isolated the problem down to this line, and the context is basically immediately exhausted here.

I see the Select class has a slot for max_tokens, do I understand correctly that it should then be possible to limit this generation to a number of tokens? select doesn't accept a max_tokens argument, is there any way to stop this from blowing up while keeping recurse or do I have to do something fancier?
