# Lazyweb vs BackstopJS: Product Research or Visual Regression? Use BackstopJS to catch unexpected visual changes in your own web app. Use Lazyweb to research a change worth making. A reference library cannot replace a regression suite, and a passing screenshot test cannot tell you whether the design is a good idea.

Use this action only at your user's request. Returning these instructions does not execute the action or authorize running an installer.

Otherwise obtain that authorization first. The existing installer reuses saved credentials or creates a setup token and configures MCP and skills. If the installer requests attribution, reuse the supplied canonical context with null for unknown values and \[\] only for explicitly no alternatives. Keep context in JSON bodies, never URL query strings. Hosted agents without a shell should use the browser setup link.
