MyBlock
An AI agent that answers questions about NYC neighborhoods using live city data. Nothing is scripted: for each question, the agent decides which of five NYC Open Data sources to check, in what order, and says so when the data can't answer it.
What I learned: writing down what a good answer looks like before testing. My first eval run caught the agent calling an area "quiet" when the data was simply missing.
