Prompt version
A prompt version is an identifiable revision or variant of a prompt that differs in wording, instructions, or model-specific conventions.

Prompt versioning is the practice of maintaining identifiable revisions of prompts so their changes and behavior can be tracked.
- How it is used
- Tracks prompt changes so teams can assess their effects on AI outputs and user experience in web applications.
- How deep it goes
- Explains storage choices, revision examples, and output tests, but stops short of a complete database-backed implementation.
- Examples
- Contrasts workout-blog wording and provider-specific translation files, then checks generated output with Vitest mocks, similarity, and constraints.
- What you can do after
- Operate/configure it by keeping identifiable revisions for comparison and rollback, with database storage when updates must avoid redeployment.

AI Agents in Action
A prompt variant is an alternative version of a prompt that can be tested against other versions for comparative results.
- How it is used
- Uses controlled prompt or profile changes to compare recommendation and other agent-task results.
- How deep it goes
- Explains version creation, batch execution, rubric scoring, and run comparison, but defers detailed prompt-engineering tactics.
- Examples
- Uses recommendation templates, system-versus-user prompt placement, connection parameters, batch runs, and evaluation exercises.
- What you can do after
- Evaluate prompt versions with prompt flow and compare their rubric scores across runs.
