ArXi:2605.14362v1 Announce Type: cross Context window efficiency is a practical constraint in large language model (LLM)-based developer tools. Paulsen shows that all tested models degrade in accuracy well before their advertised context limits the Maximum Effective Context Window (MECW) which makes context construction a quality problem, not just a cost one.
