SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prompt engineering can be cumbersome without structured guidance. This skill consolidates vendor-specific prompting best practices (Claude, GPT-5.4, Codex) into a clear, reusable workflow that helps users craft effective prompts from scratch or diagnose and refine existing prompts.

Core Features & Use Cases

  • Guides users through model-family specific prompting patterns and blocks
  • Provides ready-to-use reference materials distilled from official docs
  • Assists with learning and applying prompt design in coding and general tasks
  • Use cases include system prompts, task decomposition, and evaluation of outputs

Quick Start

Ask me to create or refine prompts for Claude, GPT, or Codex, and I'll apply vendor-specific best practices to deliver a ready-to-use prompt.

FAQPage Schema
How do I write effective system prompts for Claude Code and GPT-5.4?

To craft effective system prompts for Claude Code and GPT-5.4, apply vendor-specific prompting patterns and structured task decomposition. Distilling official documentation into actionable workflows ensures accurate coding and general task outputs.

What is the best way to debug an existing prompt that isn't producing the right output?

Debugging a failing prompt involves diagnosing it against vendor-specific best practices for Claude, GPT, or Codex. Refining the prompt design using structured reference guides helps correct task decomposition and output evaluation.

Does this approach to prompt engineering work for both coding tasks and general tasks?

Yes, prompt engineering best practices distilled from official docs apply to both coding and general tasks. The workflow guides users through model-specific patterns that handle system prompts, task decomposition, and output evaluation across domains.

How do I structure task decomposition when designing prompts for Codex models?

Task decomposition for Codex models involves breaking down complex requests into structured, reusable blocks using vendor-specific prompting patterns. Applying distilled reference guides ensures the prompt workflow generates accurate and predictable coding outputs.

Why do my GPT-5.4 prompts behave differently than my Claude prompts?

GPT-5.4 and Claude prompts behave differently because each model family requires distinct prompting patterns and blocks. Applying vendor-specific best practices distilled from official documentation ensures prompts are correctly structured for each model's architecture.

When should I use reference guides instead of creating prompts from scratch?

Use distilled reference guides when you need ready-to-use materials for vendor-specific prompting patterns or when diagnosing existing prompts. Creating prompts from scratch is best when applying learned model-family specific workflows to entirely new tasks.
