  We've added support for Prompt Tagging in the Phoenix client. This new feature gives you more control and visibility over your prompts throughout the development lifecycle.

  * Tag prompts directly in your code and see those tags reflected in the Phoenix UI.
  * Label prompt versions as `development`, `staging`, or `production` — or define your own custom tags.
  * Add tag descriptions to provide additional context or list out all tags.

  Check out documentation on [prompt tags](/docs/phoenix/prompt-engineering/how-to-prompts/tag-a-prompt).
