Agent Versioning

Agent versioning is an AI UX pattern that treats prompts, tools, and policies as versioned configs you can compare, roll back, and A/B. Teams change agent behavior without mystery regressions.

Overview

The design problem

How might we design agent versioning so people can trust and act on AI output?

Use this pattern

When this pattern fits

  • Ideal for agent development, production systems, and workflows where safely testing and comparing agent improvements is critical.

Avoid this pattern

When to skip or lighten it

  • One-off personal assistants with no shared ownership.
  • Changes so tiny that version noise outweighs benefit (batch them).
  • Environments where legal holds forbid rollback of a published agent.

Key UX elements

Anti-patterns to avoid

  • Editing production prompts in place with no history.

  • Versions labeled only as timestamps with no changelog.

  • A/B tests without a clear winner criterion.

  • Rolling forward with no one-click restore.

Pattern Definition:

Frequently asked questions

What should an agent version include?

Prompt or policy text, tool allowlist, model id, and eval notes. Show a human-readable changelog.

How do users know which version they are on?

Show version on the agent identity card and in audit receipts for consequential runs.

How does versioning relate to checkpoints?

Checkpoints restore task state mid-run. Versioning restores agent configuration across runs.

When should you A/B agents?

When metrics disagree or stakes are high enough to justify split traffic. Always define the success metric first.
