Schema Integrity Engine

The Schema Integrity Engine ensures that every output generated by an LLM conforms exactly to your application's expected data structures. By enforcing strict JSON schemas, Protocol Buffers, or custom AST shapes, it eliminates parsing errors.

How It Works

When an AI node generates a response, the output is passed through a deterministic validation layer in under 5ms. If the schema is violated (e.g., missing keys, hallucinated fields, incorrect types), the engine automatically triggers a fast-repair loop or returns a safe fallback.

import { verifySchema } from "@exogram/sdk";

const result = await verifySchema(llmOutput, userSchema);
if (!result.valid) {
  throw new Error(result.errorGraph);
}

Performance

• Validation Latency: <5ms (p99)
• Supported Formats: JSON, Avro, Protobuf, Zod
• Repair Success Rate: 98% on first pass
