Kiro Rebuilds Cross-Surface Agent Harness on Open Protocol for Seamless Handoffs
FlolightC · x · 2026-08-04
The Kiro team published a detailed technical deep dive into how they consolidated three separate agent codebases—originally split across IDE, CLI, and Web clients—into a single, unified agent harness.
- Pain Point: Previously, each client ran its own purpose-built agent with a unique session format and toolset, preventing sessions from moving across environments.
- Goal: To achieve seamless cross-surface development—starting a task on a laptop, letting it run in the cloud while closed, checking progress via mobile, and resuming in the terminal.
- Implementation: The team completely rebuilt the agent architecture on an open protocol, ensuring consistent behavior regardless of the client or runtime environment.
