Offload tool outputs over ~20k tokens to the filesystem (keep head+tail, replace body with a path ref) instead of summarizing them
Convergent 2026 harness designs keep only the head and tail of large tool results in-context and swap the middle for a filesystem path the agent can re-read on demand — a form of compaction that avoids lossy summarization entirely. Pair it with sub-agent 'context quarantine' (include_contents=none so the child sees only the latest turn and the parent gets only the final result) to stop raw logs from silently eating 40% of the window.
