Use when asked to estimate, scope, plan, or evaluate how long a coding task will take. Prevents the common failure mode where agents anchor to human developer timelines and massively overestimate. Outputs a structured breakdown with round counts, risk factors, and a final wallclock conversion. /agent-estimation by zhanghandong](https://skilld.dev/gh/zhanghandong/agent-estimation) Curated skills from @zhanghandong.
