Cost Regression Detection for AI Coding Agents
AI coding agents burn tokens invisibly; cost regression gates turn that waste into a failing build signal you can act on.
Coding-Agents
From SWE-Bench to FrontierCode: The New Agent Code Quality Era
Three simultaneous June 2026 benchmark releases rewired how we measure coding agents: correctness is table stakes; maintainability, contamination resistance, and agents per megawatt are the new axes.
Harness Engineering: Loops for Long-Running Coding Agents
LangChain tuned only the harness and lifted a coding agent from Top 30 to Top 5 on Terminal Bench 2.0 — no model change required. Here are the loop patterns that make it possible.
