Daily Research Brief 2026-08-16

📊 Token usage: estimated from retrieval and writing scale.

Covers the latest AI research, open source and industry moves, updated daily.

Editor’s Note

Today’s picture is clear: the AI industry has fully switched from a ‘model race’ to a race on the ‘runtime layer + governance layer’. GitHub’s hot list is almost entirely agent harnesses and middleware — ego-lite turns the browser into an operation surface where agents write JS directly, phone-harness lets agents take over a real iPhone, book-to-skill crystallizes textbooks into skills, and eve gives multi-agent software engineering a control plane.
