What is prompt versioning? Prompt version control for teams
Prompt versioning is prompt version control for teams: history, notes, a publishing step and rollback. You always know which copy is live, and you can restore yesterday’s wording when a change causes poor results.
It works inside the product, for the prompts your team actually uses, and does not require a company-wide git course.

What is prompt versioning
A versioned prompt has:
Draft state while you experiment
Published state when the team should use the new wording
History of earlier versions, with notes on why each one changed
Rollback to a known-good version when something breaks
Without that, every edit is a silent overwrite. You cannot prove what ran last Tuesday.
Drift across tools
Prompts change in tone, constraints and structure. When ChatGPT, Claude, Cursor and an agent each hold a slightly different copy, quality depends on which copy someone opened.
That prompts scattered across tools problem is common. Central versioning keeps the team prompt library as the source of truth and makes it easier to share prompts with your team. Tools and agents use the published version.
Draft, publish, roll back
1. Edit as a draft, so experiments stay out of everyday use
2. Add notes describing the change for colleagues and auditors
3. Publish when the team should use the new wording
4. Roll back if the change causes problems later
It is the same care you give to anything else you ship.

How it maps in Joyst
In Joyst, versioning is part of the team library within prompt management:
Owners and folders decide who manages each prompt
View, use and manage rights decide who can publish
Published prompts can be reused in agents and across AI apps
Secrets stay in the secrets vault, not inside prompt text

FAQ
What is prompt versioning?
It is version control for prompts: a history of changes, with the ability to publish new versions and restore earlier ones.
Do we need this for a small team?
Yes, as soon as more than one person edits a prompt or more than one tool uses it. Drift starts early.
Is this git training?
No. Versioning is built into Joyst. Nobody needs a git tutorial.
How does this relate to a team prompt library?
Versioning is how the library stays trustworthy when wording changes. The library holds the assets; versioning records the edits.
