You could check for the code where production programs (for mines) and
production sites (for other sites) send "Out of Resources" messages. The
production program has a handle on the production site, so both of these
could set a flag in the production site that the AI could check for, or
whenever the player gets a notification message the AI gest a message as
well. This way, the calculation of the check if a site is out of
resources remains with the production and worker programs.
