A token compression tool called Paritok, designed to reduce AI coding agent costs, was found to inadvertently increase expenses due to its operational mechanism. While Paritok claims a 64% token saving, the actual cost increase was 69.2% because the tool's proxy re-sends the full original context when the model needs to expand it. This expansion process, intended to recover lost information, creates additional token usage that is not accounted for by Paritok's internal statistics. The author proposes a fix: if the model calls an 'expand_context' tool, that specific content should be permanently pinned and passed through verbatim in subsequent turns to avoid repeated compression and expansion cycles.
