Personas From Artifacts

Create a set of simulation personas for an agent by reading what the agent actually does and who uses it — from backend payloads, UI screenshots, product/journey docs, and real user messages — rather than inventing personas in a vacuum. Personas define the WHO: the personalities, emotional states, and interaction styles of the people the agent serves. They do NOT define what the user asks about (that is test cases) — keep those separate.

This complements /design-persona (which walks you through ONE persona interactively, with voice/interruption tuning). Use this skill to go from "here is my product surface + some real traffic" to "here is a covering set of 3–6 personas" in one pass.

Drive everything through the coval CLI. Present the set and confirm before creating. If $ARGUMENTS names an agent or product area, use it in Phase 1.
