SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill solves the challenge of creating realistic, data-backed simulation personas by deriving them from actual product artifacts rather than relying on manual, speculative design.

Core Features & Use Cases

  • Artifact-Driven Synthesis: Automatically analyzes backend payloads, UI screenshots, and user transcripts to identify authentic user archetypes.
  • Behavioral Prompting: Generates specific, reusable behavioral prompts that define the who and how of user interactions.
  • Use Case: Use this skill when launching a new AI agent to quickly generate a set of 3-6 diverse personas—such as frustrated escalators or power users—based on your existing product documentation and real user feedback.

Quick Start

Run the personas-from-artifacts skill to generate a set of user personas for the customer-support-agent by analyzing the provided product screenshots and backend JSON payloads.

FAQPage Schema
How do I generate user personas for AI agent testing from product artifacts?▼

Generate user personas for agent testing by analyzing product artifacts like backend payloads, UI screenshots, and user transcripts. This skill synthesizes authentic behavioral archetypes from existing data to ensure realistic simulation coverage.

What is artifact-driven persona synthesis for behavioral simulation?▼

Artifact-driven persona synthesis is the process of deriving realistic behavioral archetypes from actual product artifacts. It analyzes backend payloads and user transcripts to create data-backed personas rather than relying on speculative design.

How many personas can I create from UI screenshots and user transcripts?▼

You can create a set of 3 to 6 diverse personas from UI screenshots and user transcripts. These behavioral profiles include archetypes such as frustrated escalators or power users for testing text and voice agents.

Do I need the Coval CLI to manage simulation personas?▼

Yes, you need the Coval CLI to create and manage simulation personas. The skill requires this CLI to operate within the Coval evaluation platform for text and voice agent behavioral testing.

Can I use backend JSON payloads to define behavioral prompts for voice agents?▼

Yes, you can use backend JSON payloads to define behavioral prompts for voice agents. The skill analyzes these payloads alongside user transcripts to generate specific, reusable behavioral interaction prompts.
