Can Google Antigravity 2.0 Pass the “Napkin Challenge”? 📝🚀

Google Antigravity 2.0 能通过“餐巾纸挑战”吗？📝🚀

🚀 From Napkin Sketch to data-driven real-estate advisor Agent in Under 40 Minutes? 🚀 Can a coding agent really work autonomously on complicated problems without human intervention? I decided to put Google’s new Antigravity 2.0 and Gemini 3.5 to the test: The Napkin Challenge. 📝 🚀 从餐巾纸上的草图到数据驱动的房地产顾问智能体，只需不到 40 分钟？🚀 编码智能体真的能在没有人工干预的情况下自主解决复杂问题吗？我决定对谷歌全新的 Antigravity 2.0 和 Gemini 3.5 进行测试：餐巾纸挑战 (The Napkin Challenge)。📝

The goal: Build and deploy a real estate investment advisor - based on real-world data, starting with nothing but a rough sketch on a napkin. The Result? With the right context, yes! 目标：构建并部署一个房地产投资顾问——基于真实世界数据，且仅从一张餐巾纸上的草图开始。结果如何？在提供正确上下文的情况下，答案是肯定的！

I used: Antigravity 2.0 & Gemini 3.5: Architect and execute the plan. Agent CLI Skills: Scaffold, build, test and evaluate the agent using ADK.3. Developer Knowledge MCP: Provided necessary context to connect to BigQuery MCP and integrate the census dataset for grounded investment advice. Parallelized Workflow using sub-agents: While the system ran the evaluation suite, it simultaneously deployed the agent to Cloud Run. 我使用了：Antigravity 2.0 和 Gemini 3.5 来架构并执行计划。Agent CLI Skills：使用 ADK.3 对智能体进行脚手架搭建、构建、测试和评估。Developer Knowledge MCP：提供了连接 BigQuery MCP 并集成人口普查数据集的必要上下文，从而实现基于事实的投资建议。使用子智能体的并行工作流：当系统运行评估套件时，它同时将智能体部署到了 Cloud Run。

The Outcome: Built and deployed in under 40 minutes. Zero human input beyond a napkin sketch (other than approving the plan and setting the model and region). 100% passing scores on evaluation cases, with responses delivered in under 30 seconds. A fully functional real estate advisor providing data-driven analysis on short and long term investments. 成果：在 40 分钟内完成构建与部署。除了餐巾纸草图（以及批准计划、设置模型和区域）外，无需任何人工干预。评估案例通过率为 100%，响应时间不到 30 秒。一个功能齐全的房地产顾问，能够提供关于短期和长期投资的数据驱动分析。

The “Napkin Challenge” proves that when you combine the right context with powerful models, the barrier between an idea and a deployed product has virtually disappeared. I challenge you: What is your “napkin” project? Try it with Antigravity 2.0 and Gemini 3.5. 📝 🚀 “餐巾纸挑战”证明，当你将正确的上下文与强大的模型相结合时，从创意到部署产品之间的障碍几乎已经消失。我向你发起挑战：你的“餐巾纸”项目是什么？快用 Antigravity 2.0 和 Gemini 3.5 试一试吧。📝 🚀
