Migrating a Custom GPT to a Skill

You may have a Custom GPT that took hours of testing, rewriting, and edge-case fixes to make it dependable. With OpenAI changing where new GPTs can be created and expanding Skills as a reusable workflow architecture, that proven work is worth deliberately carrying forward. For this lesson, you will use an existing Custom GPT and follow a machine-guided migration process. Then, you will audit its configuration, convert the durable workflow into a Skill, test both versions with the same prompts, and repair only the differences that matter.
