The authors fixed the harness’s core execution loop and varied planning, available actions, and context-management strategy.
Coding-agent harness choices should match model skill and context budget
Across 176 matched configurations, the authors isolate how planning, tool interfaces, and context management affect coding-agent accuracy, cost, and trajectory length.

Coding harness components are conditional: context management matters as context shrinks, planning helps weak models at accuracy and strong models at cost, and bash-only suits capable models.
