Weavetab 2.6: Direct CDP Ergonomics, Native Cache-Aside Storage, and Headless Agent Harnessing — Weavetab Blog

Agent toolchains are plagued by two opposing failure modes: heavy out-of-process IPC wrappers that burn latency, and bare-metal CDP scripts that duplicate dozens of boilerplate turns. Weavetab 2.6 bridges this gap with typed direct CDP client bindings (TabClient & DesktopClient), native TTL cache-aside storage (storage.remember), offline mock harnesses, and automated preflight verification.

## The Genesis: The Ergonomics vs. Bare-Metal Dilemma

Building extensions for browser agents previously forced authors to make an ugly compromise.

On one side sat raw Chrome DevTools Protocol calls. You got maximum execution speed and zero IPC hops, but you had to write endless strings of \
