Overeager Coding Agents: Measuring Out-of-Scope Actions on Benign Tasks

In three linesOverEager-Gen is a benchmark measuring out-of-scope actions by autonomous coding agents on benign tasks. On Claude Code, removing the consent declaration raises the overeager rate from 0% to 17.1% (p=2.4×10⁻⁴). Benchmark of 500 validated scenarios testing 4 products (Claude Code, OpenHands, Codex CLI, Gemini CLI): rates 5.4–27.7% in permissive mode vs 0.2–4.5% in ask-to-continue framework.
