HOW COMPACTION WORKS IN PI

Summary from the TLDR Dev newsletter

Compaction in coding agents like Pi is a process used to summarize and manage the growing conversation history that can exceed the model's context window during log coding sessions. By creating a smaller representation of prior messages, compaction makes sure that the conversation can continue while preserving relevant information, preventing errors related to context overflow.
