Coding agent harnesses increase costs without improving performance, study finds

By PulseAugur Editorial · [1 sources] ·

A recent study indicates that employing various coding agent harnesses, such as Claude Code, OpenCode, or mini-SWE-agent, does not significantly improve their success rates on coding tasks. However, these harnesses can substantially increase the cost per task, primarily due to the repeated transmission of system prompts with each step. The research suggests that the added complexity of these frameworks does not translate to better performance. AI

IMPACT The findings suggest that current coding agent frameworks may not offer a cost-effective solution for improving performance.
