last night i spent some time building a browser agent with stagehand from @browserbase and deepagents from @LangChain i wanted to build something that required pretty complex web navigation to prove the value of agentic browser use! my agent plays a game called "map tap" where you are assigned a city around the globe, and have to drag the map, zoom in, and click as close to the given city as possible. you get points based on how close you are. 1. one shotted the agent w/ browserbase + langchain docs, it scored ~300/1000 points 2. asked my coding agent to review the trace and make it faster (smaller model) and more accurate (higher score) 3. came back 10 minutes later to see a perfect score screenshot in my trace here's a guide on how to build your own browser agent! https://docs.langchain.com/oss/python/integrations/tools/stagehand
