I uploaded a new version of the filter module yesterday, but the error 
below seems unrelated.

Short answer: Change `filtercommand` to `filter`.

Long answer: The standard way to specify the command to be executed in 
each snippet is to use `filtercommand`. This should be the FULL command 
(as you would run on the command line). So in case of asymptote, it should 

filtercommand={asy -tex context -outformat pdf -outname 
\externalfilteroutputfile\space \externalfilterinputfile}

Since many commands are of the form:

    command-name <options> input-name

a shortcut is provided in the filter module. Instead of saying

filtercommand={command-name <options> input-name},

you can say

filter={command-name <options>}

In the example that you posted, you are using `filtercommand=....` but the 
input filename is missing, so asymptote launches an interactive promt.
