ui-verifier-web 0.6.4

First public release.

The ui-verifier-web:ui-verifier-web agent verifies UI changes in a running web app or browser extension against a checklist: drives the browser with agent-browser, measures what it sees, and returns a pass/fail report with screenshots. Never modifies code.

claude plugin marketplace add Comp0te/claude-plugins
claude plugin install ui-verifier-web@compote --scope project

Requires the agent-browser CLI 0.38.0 or newer and its skill:

npm install -g agent-browser && agent-browser install
npx skills add vercel-labs/agent-browser --skill agent-browser -g -a claude-code -y

When either is missing, the agent now stops with exactly these commands. Project facts go in .claude/docs/ui-verification.md.
