I Built an Agent Skill That Tests Your App Like Four First-Time Users

Description and use

First User Audit automatically tests an app from four first‑time‑user perspectives, uncovering friction points developers often miss.

Problem

First‑time visitors often get stuck before reaching a useful result, but developers are too familiar with the app to spot these friction points.

Outcome

The skill surfaces friction that developers overlook, enabling targeted fixes and smoother onboarding for new users.

Workflow

• Identify what first success means for the app.
• Explore the onboarding journey through Impatient, Skeptic, Mobile, and Breaker personas.
• Record blockers with browser evidence and reproduction steps.
• Prioritize issues and propose safe technical fixes.
• Verify changes through fresh sessions when supported.

Evidence

I built First User Audit — an open-source Agent Skill that helps coding agents explore your application from four different first-time-user perspectives.

Source

It focuses on one question: Can someone reach the first useful result without getting stuck?

Source

The skill uses four simulated user behaviors: Impatient, Skeptic, Mobile, Breaker.

Source

It guides your coding agent through a simple process: Identify what first success means for your app. Explore the onboarding journey through four different behaviors. Record blockers with browser evidence and reproduction steps. Prioritize issues and propose safe technical fixes. Verify changes through fresh sessions when supported.

Source

You can install it using the skills CLI, or simply copy this prompt into Claude Code, Codex, or another compatible coding agent.

Source

The skill requires connected browser tooling for the audit.
