Prompt Version Diff
Compare prompt versions and categorize changed lines deterministically for human review.
The problem it solves
Prompt Version Diff Prompt Version Diff compares two local prompt files and groups added and removed nonblank lines into visible categories: constraints, context, examples, and instructions. It uses documented deterministic cues—never an AI model—so every classification is reproducible and reviewable.
Who Prompt Version Diff is for
- Developers and maintainers who need reviewable evidence before changing or releasing software.
- Users working with prompts, diff, prompt engineering who want the documented v1.0.0 behavior.
- People who prefer an open-source release with visible limitations, source, and license terms.
Intended result
Compare prompt versions and categorize changed lines deterministically for human review.

Verified examples
Screenshots are shown only when the current README references a local source image. Otherwise, repository example files are linked directly.
Verified release evidence
This project does not currently publish a screenshot or dedicated example folder. The current README, tests, changelog, tagged release, and source repository remain the verified examples of its behavior.
Platforms and implementation
The public release claims only the cataloged platforms and technologies.

Quick start
The shortest documented path into the current release.
python -m pip install "prompt-version-diff @ https://github.com/loganpendragonmultiverse/prompt-version-diff/releases/download/v1.0.0/prompt_version_diff-1.0.0-py3-none-any.whl"
prompt-version-diff prompt-old.md prompt-new.md --markdown changes.md --json changes.jsonThe exit code is 1 when meaningful lines changed, 0 when they match, and 2 for unreadable input. Blank-line-only formatting changes are ignored.
Current limitations
These boundaries are part of the product and prevent the page from implying unverified capability.
Files remain local. Reports repeat prompt text and can expose supplied context, so review them before sharing. Categories are lexical review aids, not semantic understanding. The tool does not detect every instruction, resolve conflicts, judge prompt quality, compare model behavior, or send content to an API.
Privacy and licensing
Review the actual data boundary before using a tool with sensitive inputs.
