Write the schema
type says the shape, properties names the fields, required lists the ones that must be there, and enum keeps a field inside a fixed set of values.
echo '{"type": "object", "properties": {"severity": {"type": "string", "enum": ["P1", "P2", "P3"]}, "summary": {"type": "string"}}, "required": ["severity", "summary"]}' > ~/llm-lab/schema.json - 2 locked · each failed submit reveals one
