Agent Harnesses Explained: Inside the Stack Behind Antigravity, Claude Code & Cursor

Why watch

This video explains agent harnesses as the architectural layer that enables fully autonomous coding, covering the three-layer stack with Gemini 3.8 Flash, Antigravity Boost, and Google Skills. It demonstrates practical ADK implementations comparing linear vs closed-loop harnesses, and addresses how to configure memory, tools, and guardrails for reliable agent operation. Targeted at developers building autonomous coding agents and technical leaders scaling AI infrastructure.
