Output Contract Enforcer

Validates that a DAG node's output matches its declared JSON schema before passing to downstream nodes. The glue that makes multi-agent DAGs reliable. Without this, downstream nodes receive unpredictable input and the DAG breaks.

When to Use

✅ Use for:

• Validating a node's output against its declared schema
• Generating output schemas from natural-language output descriptions
• Debugging why a downstream node rejected its input
• Ensuring contract compatibility between connected nodes

❌ NOT for:

• Assessing content quality or correctness (use dag-quality)
• Grading skill quality (use skill-grader)
• General JSON schema work outside DAG context
