Prompt Versioning Skill for ChatGPT: Compare Changes and Define Rollback Criteria
Document why a prompt changed, which cases it affects, and how to test it. Compare versions on the same inputs to detect regressions, verify the intended improvement, and define rollback criteria.
中文Install in ChatGPT
Use an eligible ChatGPT workspace with permission to create skills and, for uploads, upload permission. The installation path for this text-only adaptation was checked against OpenAI documentation. Workspace runtime verification is pending.
- Download claude-plugin/prompt-architecture/skills/prompt-versioning/SKILL.md from the pinned GitHub source. Keep the name, description, and instructions for prompt-versioning together as a standalone text skill.
- In a ChatGPT workspace with skills and uploads enabled, open Plugins, Skills, Create, and Upload from your computer. Choose a skill package format accepted by the file picker. You can also choose Create with editor and enter the original name, description, and instructions.
- After the scan completes, check that prompt-versioning appears in Installed. Type @ in a new chat, select the skill, and use the fictional example on this page to check the output.
Example task
A fictional book-note summarizer keeps page numbers in v1 but misses readers' questions. v2 adds a question field. Create a change note and test matrix for notes with both fields, notes with page numbers only, and notes with no page numbers.What to check
Use the same inputs on both versions. Check page numbers against the source, mark missing fields, and preserve the supplied questions. Specify when to revert if the page-number behavior regresses.

Frequently asked question
Should I test a one-word change?
Check whether the wording can alter format, classification, or meaning. Run the existing examples and add one case that distinguishes the old and new behavior.
