From the source SKILL.md

Validate critical technical risks from the architecture vision through minimal proof-of-concept implementations, aided by the arn-spark-spike-runner agent for POC creation and execution. This is a conversational skill that runs in normal conversation (NOT plan mode). The primary artifacts are spike POC code in isolated directories and a spike results document.
