Install per version and agent rules

Install

Agent policy: Ask first
  • Not verifiedNot installed by the catalog: the nightly run installs modules, not libraries.
  • Your agent waits until you type: Install @open-mercato/web-research@0.9.0
yarn add @open-mercato/web-research@0.9.0

The catalog never installs it, so it is never verified.
