A/B 测试与增长实验
原名：ab-testing
把页面或活动改动变成可验证的实验，先确定假设、样本量与判断标准。
中文 Skills 技能说明
适合一人公司比较两版首页、报名流程或营销文案。提供当前转化率、可用流量、业务目标和实验周期，技能先区分主要指标与护栏指标，再安排分流、样本量和停止规则。输出实验计划、埋点清单及结果解读模板。流量不足时要说明不确定性，不能把短期波动说成增长结论；上线分流和修改埋点需人工确认。核心规划可使用本地数据，统计工具和网站权限由用户提供。
上游能力依据
上游原始适用说明：When the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.
