Core UX Detective is a production-ready Claude Code skill (quality score 70/100) in the ux-research sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/core-ux-detective/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when (1) mapping what users can actually do in the app, (2) defining canonical user journeys/flows, (3) creating the AI-readable user model (core-user-model.json), (4) reviewing whether a new feature introduces a new core path, (5) other skills (help, marketing, onboarding) need authoritative task/path definitions to consume.
The Core UX Detective skill is built for product managers, product designers, and cross-functional teams planning, shipping, and measuring product features. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.
