Ara Khan is a founding engineer at Cline, an AI coding-agent platform. He writes and speaks about building production-quality AI agents, including agent maturity, evaluation, context engineering, and reliable agent design.
Cline’s Terminal-Bench Gains Came From Harness Tuning, Not Model Switching
Ara Khan of Cline argues that AI evals are too noisy to treat as truth but too useful to replace with vibes. Using Cline’s Terminal-Bench work as the case study, he says the company’s jump from 43% to 57% came from harness changes — container CPU and memory, longer timeouts, and model-family-specific prompting — rather than a better model. His prescription is to run evals skeptically, inspect failed traces, allocate failures by cause, and improve only the levers that survive contact with product behavior.
Every Addition to an AI Agent Can Make It Worse
Ara Khan of Cline argues that agent maturity is less about adding autonomy than about knowing what not to add. In a talk structured around four levels of agent building — from frameworks to state machines, Kanban-managed workflows and cloud deployment — Khan says frontier models increasingly reward simpler prompts, deliberate architecture and visible human control. His central warning is that every extra instruction, abstraction or automation layer can make an agent worse.
