In agentic workflows, raw command outputs and state recollection after compaction contribute to major token waste. Agents often pull raw terminal output into context even when they only need a few anchors, then pay the same cost again later when compaction forces them to reread files or rerun commands. CtxSift was built to cut that loop down to two operations: keep only the signal that matters now, then recover it later without rebuilding the whole state trail.
