Unverified50% confidenceOpinionExact time
The effectiveness of a coding agent is the product of the model and the harness; ignoring the harness and purely pursuing model upgrades is like putting a stronger engine in a race car while ignoring the gearbox and tires.

UnverifiedAs model capabilities gradually converge, harness quality will become the core competitiveness that distinguishes excellent coding agents from mediocre ones.77% similarUnverifiedIf a coding agent product's advantages come primarily from the harness, those advantages may be quickly erased once competitors connect to the same underlying model and optimize their own harness.72% similarUnverifiedAfter running multiple ticket-to-PR agents, a team concluded that the main reason coding agents perform poorly lies in the external framework (harness), not model capability.70% similarUnverifiedHard constraints (architectural design, linter, CI, compiler) are more effective than soft constraints (skills, memory, prompt) at ensuring Agent code quality, because hard constraints are deterministic rules enforced by machines that Agents cannot bypass.64% similarUnverified能力不够的模型会因为要处理Harness的优化任务而分散本身的交互能力，导致整体表现下降64% similar
