Pattern A (Recommended)

Strict Typed JSON Envelope

Enforces top-level status, code, message, and data objects validated against strict schema contracts before returning to caller.

Key Technical Advantages:

  • Zero JSON parser crashes
  • Type-safe SDK ingestion
  • Deterministic status codes
  • Self-documenting payload structures
Pattern B (Alternative / Legacy)

Raw Unstructured Prompting

Relies on prompt engineering instructions (e.g. "return only valid JSON") which frequently fail due to conversational filler.

Characteristics & Trade-Offs:

  • No schema definition needed upfront
  • Flexible free-form text output
  • Good for subjective human dialogue
