About this hackathon
A one-day Claude Code hackathon from the Anthropic Claude Community, co-hosted with AI workforce platform HappyRobot at its Madrid office on Saturday, Nov 28, 2026. Every team starts from the same weak sales agent on HappyRobot and builds a Claude agent that diagnoses lost calls, edits the sales agent, re-tests it and keeps or rolls back each change on its own. Scoring is based on sales uplift against hidden simulated buyers, plus loop safety and the demo. For builders with 2–4 years of experience who have shipped with LLMs or agents; about 30 seats, individual applications, placed in teams of 3–4. Each participant gets $100 in Claude API credits.

一句话简介：Anthropic Claude 社区与 AI 员工平台 HappyRobot 在马德里合办的一日 Claude Code 黑客松，主题是「让 Agent 去教练另一个 Agent」。
看点：所有队伍从同一个表现很差的 HappyRobot 销售 Agent 起步，用 Claude 做一个能分析丢单原因、改写销售 Agent、重新测试并自动保留或回滚改动的教练 Agent；最终按隐藏模拟买家上的销售提升打分，另看改动是否安全可解释和 Demo；面向 2—4 年经验、熟悉 Python 或 TypeScript、做过 LLM/Agent 项目的开发者，约 30 席、按个人审核，现场分 3—4 人队；每人 100 美元 Claude API 额度，管早午餐。
奖金：奖品待公布；每人 100 美元 Claude API 额度
截止日期：11月28日（现场当天，报名需审核）
