A controlled study has revealed that switching between various coding-agent harnesses, such as Claude Code, OpenCode, or mini-SWE-agent, results in only marginal improvements in pass rates. The findings indicate that rerunning the same setup yields similar outcomes, challenging the notion that more sophisticated tools necessarily enhance coding efficiency.
However, the financial implications are substantial. The cost per task can triple when utilizing these advanced harnesses, primarily due to the repeated system prompts that must be resent with each step of the coding process. This raises important questions about the cost-effectiveness of investing in these high-end solutions for coding tasks.
As organizations continue to explore AI-driven coding agents, this study highlights the need for a careful evaluation of both performance and cost, suggesting that simpler setups may suffice without sacrificing quality.
