Be sure to watch the YouTube stream where we talk about how these plugins work in depth.
These two plugins helped me get into the top 10 of the dark forest score contest for v0.5.
auto-conquer is a plugin that would find the best planets to conquer. It is currently tweaked for late game, so you'll have to read the code and change parameters if you are just starting out!
auto-silver is a plugin to re-distribute silver mines to available planets. It's also tweaked for late game, ignoring silver mines with small amounts of silver.
