SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill guarantees that the output from one node in a multi-agent DAG reliably conforms to a predefined schema, preventing downstream errors and ensuring data integrity.

Core Features & Use Cases

  • Schema Validation: Validates JSON output against a specified schema, checking for required fields, correct types, and constraint adherence.
  • Contract Generation: Can generate JSON schemas from natural-language descriptions of expected output.
  • Debugging: Helps identify and diagnose contract mismatches between connected DAG nodes.
  • Use Case: In a complex DAG, ensure that a data processing node always outputs a status field (pass/warn/fail) and a summary string before its output is consumed by a reporting node.

Quick Start

Validate the output JSON against the provided schema.

FAQPage Schema
How do I validate JSON output against a schema in a multi-agent DAG?

To validate JSON output in a multi-agent DAG, this Skill checks your data against a declared JSON schema. It verifies JSON parseability, required fields, type correctness, and constraint adherence to ensure reliable data flow between connected nodes.

What is a DAG node output contract and when do I need schema validation?

A DAG node output contract is a predefined JSON schema that guarantees a node's output structure. You need schema validation when data processing nodes must reliably pass specific fields, like a status or summary, to downstream reporting nodes.

Can I generate a JSON validation schema from a natural language description?

Yes, you can generate a JSON validation schema from a natural language description. This Skill creates schemas from your descriptions of expected output, which helps establish output contract compliance for multi-agent systems without manual schema coding.

How do I debug contract mismatches between connected DAG nodes?

To debug contract mismatches between connected DAG nodes, this Skill identifies and diagnoses violations in your JSON output. It checks for missing required fields, incorrect data types, and constraint failures to pinpoint where the data flow breaks.

What is the best way to enforce required fields and type correctness in JSON outputs?

The best way to enforce required fields and type correctness in JSON outputs is by validating the data against a declared JSON schema. This Skill checks for JSON parseability, required fields, type correctness, and constraint violations to prevent downstream errors.
