Hello World
This skill exists to prove the SkillHarness pipeline is wired correctly. It must:
- Accept an optional
whoinput (default: "world"). - Return
{"greeting": "hello, <who>"}exactly.
There are no side effects. There is no shell. There is no file IO.
If this skill cannot be invoked end-to-end, the SkillHarness is broken and no other skill should be trusted. Treat that as the smoke-test gate.
