From the source SKILL.md

Create structured use case documents in Cockburn fully-dressed format through a team-based conversational process, aided by the arn-spark-use-case-writer agent for drafting and revising, arn-spark-product-strategist for business relevance review, and arn-spark-ux-specialist for flow quality review (both are greenfield agents in this plugin -- if arn-spark-ux-specialist is unavailable, the skill proceeds with product strategist review only). This is a conversational skill that runs in normal conversation (NOT plan mode).
