MockHunter — Live Page Reality Check

Overview

MockHunter is a Claude Code skill that audits a live web page and tells you, for every visible value, whether it is real, mocked, LLM-generated, hardcoded, broken, or unknown. It is built for vibe-coded apps (Lovable, Bolt, v0, Replit, AI Studio, Cursor Composer) where the UI may look complete but the data layer often is not. It uses Playwright MCP to drive a real browser, then traces each visible value through the network and DOM to its source.

This skill adapts the upstream CodeShuX/mockhunter project (community source).

Because this workflow drives a real browser against live pages, treat it as an interactive audit tool, not a plugin-safe read-only helper. Default to observation-only until the user confirms the target is theirs, identifies a safe test account or environment, and explicitly approves any click, submit, or authenticated action that can mutate state.

When to Use This Skill

• Use when auditing an AI-generated UI to find out which values are actually wired up
• Use when reviewing a contractor or teammate's deliverable before sign-off
• Use before showing a vibe-coded MVP to a customer or investor
• Use when a dashboard "looks too clean" — every metric uniformly round, all timestamps clustered, no variance — and you suspect seeded data
