The previous two posts covered how events flow from the SDK to the UI. This post focuses on visualizing one specific type of event: tool calls. Tool invocations are the most frequent operations in an Agent application. A typical task might call tools twenty or thirty times—reading files, writing files, executing commands, searching code.

TimelineView is the main body of the workspace, filling all the space between the sidebar and the input box. Its view hierarchy is shallow: Time
State of Software Engineering in 2026: A Reality Check Beyond the AI Hype Three and a half years ago, Matt Welsh, PhD and former Google engineer, published "The End of Programming" in Communications of the ACM and declared that classical computer science was over. The meteor had hit. Engineers were the dinosaurs. The state of software engineering in 2026, he implied, would look nothing like what
