ONE AGENT, EVERY SURFACE: HOW WE BUILT THE KIRO AGENT HARNESS

Summary from the TLDR AI newsletter

Kiro is an agentic IDE with features such as specs, steering, and hooks. The Kiro agent harness is a lightweight server-side process that runs alongside codebases, starts quickly, and owns everything on the agent side. The IDE, CLI, and Web clients own how the user interacts with the agent and how it presents the agent's work. The only way to cross that boundary is through the defined protocol interface. The well-defined interface between server and client means the agent code evolves independently of the clients.
