hello-world

Quick Review

A basic test/demo skill with clear but minimal documentation. The description and instructions are straightforward enough for invocation (respond with a specific greeting), and task knowledge is complete for this trivial task. Structure is simple but adequate for such a minimal skill. However, novelty scores zero as this is explicitly a test skill with no practical utility - a CLI agent could trivially produce 'Hello World' responses without any skill framework, making this skill purely demonstrative rather than cost-saving.
