Can I use this for older GPT models like GPT-4o?

While specifically optimized for the GPT-5 series, the best practices for system/developer message separation and testing apply effectively to all modern LLMs.

How does this skill improve GPT-5 performance?

It provides structured templates and a rigorous 'Draft-Test-Patch' workflow to eliminate ambiguity and improve instruction following.

Does it support JSON schema enforcement?

Yes, it includes specific guidance for creating robust structured-output prompts, including explicit schema constraints and error handling.

How do I handle hallucinations with this skill?

The skill includes specific rules, such as cite-only-from-source constraints and 'I don’t know' fallback policies, to minimize fabricated information.

데이터 과학 및 ML

Optimizes and iterates high-signal prompts for OpenAI GPT-5 models to ensure structured, reliable, and hallucination-free outputs.

This skill empowers developers to master the nuances of OpenAI's GPT-5 series by providing standardized frameworks for system, developer, and user messages. It streamlines the prompt development lifecycle—from drafting and multi-case testing to iterative patching—ensuring AI interactions are robust against edge cases and strictly adhere to structured formats like JSON. Whether you are building complex autonomous agents or specialized tools, this skill helps you navigate reasoning tradeoffs and mitigate common failure modes like format drift and tool misuse.
