Optional customization tool for greenfield projects. This skill should be used when the user says "greenfield init", "arn spark init", "initialize greenfield", "setup greenfield", "greenfield setup", "start greenfield", "configure greenfield", "set up greenfield", "init greenfield", "greenfield configuration", "review greenfield config", "customize greenfield config", "greenfield settings", "Figma setup", "Canva setup", "add Figma", "add Canva", "design tool setup", or wants to customize Arness Spark configuration, add design tool integrations (Figma, Canva), or review current greenfield settings. Arness Spark auto-configures with sensible defaults on first skill invocation — this init is optional. Design tool integration (Figma/Canva) remains available only through this skill.
