VS Code shifts focus from AI models to agent harness engineering

The VS Code team's recent documentation on their Copilot agent harness reframes the focus from solely improving AI models to enhancing the surrounding infrastructure. Their internal benchmark, VSC-Bench, revealed that increasing reasoning effort beyond a certain point can degrade performance, suggesting that tuning the harness—including context assembly and tool exposure—is more critical than chasing incremental model upgrades. This shift is supported by recent developments like the Agents Window, Agent Skills, and Martin Fowler's framework, all of which emphasize the harness as the true product surface for coding agents.
