What do you keep in a prompt registry?
A prompt registry is a shared place for saved instructions. In PromptLayer, a template can include the messages, the blanks your app fills in and model settings. Save an edited version and use its history to see what changed.
How does your app know which version to use?
A release label is a name that points to a saved version. An app set up to request a label like staging gets the version behind that name. Keep a test label separate from the one the live app requests. Moving the live label can affect requests without an app code release, so check what the app actually asks for and who can move the label.
What should you check before sharing or moving templates?
PromptLayer Free lists five users, one workspace and 2,500 requests per month. It lists evaluation cell executions separately. The pricing table places role-based access controls and deployment approvals on Enterprise. Keep the template text, variable names, settings and selected version in a separate copy. The SDK can retrieve a template by label. Check separately how you would carry over its version history, permissions and evaluation results.
Which instructions would the app use after one edit?
Draw version 1 and version 2 of a fictional workshop-reply template. Use paper only and leave accounts, credentials, integrations and live labels untouched.
- Mark the two labelsPoint Live at version 1 and Test at version 2. Write the wording someone would receive in each copy.
- Record the release decisionIf version 2 invents a room when the room is unknown, keep version 1 for Live. Write which version you would keep and what the next test needs to check.
