The Prompts page is your prompt version control system. Every prompt change creates a new immutable version — previous versions are never overwritten. You assign labels like production and staging to versions, and your running application fetches prompts by label at runtime using the SDK. This means you can update a production prompt without touching your code.

​
The prompt library

The main Prompts page shows all prompts in your project as a list. Each row shows the prompt name, the number of versions, which labels are active, and when it was last updated. Click any prompt to open its version history view.

​
Creating a prompt

1

Click New prompt

On the main Prompts page, click New prompt.
2

Choose a name

Enter a slug-style name for the prompt, e.g. support-reply or product-description-generator. This name is used by the SDK to fetch the prompt at runtime.
3

Choose a type

  • Text — a single string with {{variable}} placeholders for dynamic content
  • Chat — an array of message objects (role, content) with placeholder support
4

Write the prompt

Enter your prompt in the editor. Use {{variable_name}} syntax for any values you want to substitute at runtime.
5

Add model config (optional)

Optionally fill in suggested model, temperature, and max_tokens. These are stored with the prompt for reference but are not enforced by the SDK — you decide whether to use them.
6

Set a label

Assign a label, typically staging, to this initial version.
7

Add a commit message

Write a short description of what this version contains. Commit messages appear in the version history.
8

Save

Click Save. Version 1 is created and ready to fetch via the SDK.

​
Version history

Each prompt’s detail view shows a table of all versions:
ColumnDescription
VersionSequential version number, starting at 1
LabelsActive labels on this version (e.g., production, staging)
Commit messageDescription of what changed
CreatedTimestamp and author
ActionsView, promote, roll back
Click View to see the full prompt text for any version. Click Promote to move a label to this version. Click Roll back to move the production label to this version in one click.

​
Labels

Labels are mutable pointers to specific prompt versions. The recommended workflow is:
  1. Create a new version and assign it the staging label
  2. Test the new version in your staging environment
  3. When ready, promote it to production by clicking Promote or by calling updateLabels() in the SDK
Your application code fetches prompts by label: 
const prompt = await promptClient.get("support-reply", { label: "production" });
The label pointer updates immediately when you promote. Your running application will pick up the new version on its next prompt fetch (respecting the 5-minute cache TTL, or immediately if you clear the cache).
Labels are not exclusive by default. You can have production on multiple versions simultaneously. If you want a single canonical production version, remove the label from the old version before promoting the new one.

​
Protected labels

Some labels — such as production — can be locked so that only users with Admin or Owner roles can move them. Configure protected labels in Settings → Prompts. This prevents accidental promotion from a Member-level account.

​
Rollback

To roll back to a previous version:
  1. Open the prompt’s version history
  2. Find the version you want to restore
  3. Click Roll back — this moves the production label to that version instantly
You can also roll back via LumiqPilot: “Roll back the support-reply prompt to the previous production version.”

​
Dependency tracking

When one prompt references another (e.g., a system prompt that embeds a shared policy block), you can declare the dependency in the prompt metadata. LumiqTrace tracks the dependency graph and warns you if a dependency is about to be archived or rolled back.

​
Fetching prompts from the SDK

See the full SDK reference for TypeScript and Python prompt fetching, compilation, and cache management. Quick reference: 
import { lumiqtrace, PromptClient } from "@lumiqtrace/sdk";

lumiqtrace.init({ apiKey: process.env.LUMIQTRACE_API_KEY! });
const prompts = new PromptClient(lumiqtrace.getClient());

// Fetch by label
const prompt = await prompts.get("support-reply", { label: "production" });

// Compile variables
const text = prompts.compile(prompt, { customer_name: "Alex", order_id: "123" });
