Step 1: Customize Prompt Variables

Step 2: Generated Prompt Output

Design a production Python data pipeline that: Source: REST API (paginated JSON) Transformation: deduplicate by ID, normalize phone numbers to E.164 Destination: PostgreSQL table Volume: 500K records/day Provide: 1. **Architecture diagram** (ASCII) 2. **Complete Python code** with: - Type hints throughout - Structured logging (loguru or standard) - Retry logic with exponential backoff - Error handling with dead letter queue pattern - Progress tracking 3. **Unit tests** for the transformation logic 4. **Docker + requirements.txt** setup

Comprehensive Technical Analysis & Guide

In-depth breakdown, safety recommendations, and operational mechanics.

1Architecture & Theoretical Basis of this Prompt

This template leverages structural role calibration and negative constraint enforcement. By explicitly scoping the output parameters for GPT-4o, it reduces token waste and focuses model inference on high-value synthesis.

2Optimizing Temperature & Inference Hyperparameters

For technical coding and code review prompts, set model temperature to 0.1–0.2 for maximum determinism. For creative ideation and artistic prompts, set temperature to 0.7–0.9.

3Chaining Outputs into Production Pipelines

The structured markdown formatting makes it trivial to parse key sections (bugs, recommendations, replacement code) programmatically using standard regex or structured JSON schemas.

4Ethical & Defensive Prompt Practices

Always verify mission-critical code outputs with automated testing suites (unit tests, integration tests) before deploying LLM-generated recommendations into production environments.
