Prompt Version Management & A/B Testing
Overview
Prompts are code — and they need version control, testing, and staged rollouts just like software. A single changed word can swing accuracy by 20%. This skill covers how to manage prompt versions systematically, run controlled experiments, and deploy prompt changes with confidence.
Core Concepts
Why Prompt Versioning Matters
| Problem | Without Versioning | With Versioning |
|---|---|---|
| A prompt change breaks behavior | No way to roll back | Instant rollback to previous SHA |
| "Which prompt is in production?" | Check Slack history | Single source of truth |
| A/B test needed | Manual, error-prone | Structured experiment framework |
| Regression from edit | Undetected until users complain | Automated eval suite catches it |
| Collaboration | Merge conflicts in shared docs | PR-based workflow with reviews |
