A2A — 用数据计数，而非评论
A2A（Agent2Agent）是一项开放协议，让不同团队构建的 AI 智能体能够互相发现并委派任务。它由 Google 于 2025 年 4 月发布，现已归入 Linux Foundation。所有人都在问它是否真被采用，得到的多半是观点。本页只用测量回答：KoPass 每天统计 A2A 仓库。

已测量的增长
- +964一天内新增星标
基于 2026-08-30 与 2026-08-31 两次均被测量的 1 586 个仓库。只比较两次都存在的仓库：期间新增的仓库会把星标一次性带入，如同当天获得。

这些数字如何得出
KoPass 每天就四个声明主题查询 GitHub API — a2a-protocol、agent2agent、a2a 与 agent-to-agent — 并记录结果。筛选依据仓库声明的主题，而非文本：在描述中搜索“a2a”会把所有顺带提及该协议的内容都收进来，包括声明不使用它的项目。超过三十天未被测量的仓库将退出统计。
本页没有说的事
它只测量 GitHub 上公开的部分。私有的、企业内部的或发布在别处的实现都不会出现。星标数不等于用户数。而且这些数字都不是预测，它们描述的是已经完成的测量。
官方来源
协议规范发布于 a2a-protocol.org，参考代码位于 github.com/a2aproject/A2A。KoPass 不取代其中任何一个，它统计的是围绕它们生长出来的东西。
