# Saving & Publishing

Every Spara agent has two states at any given time: a **draft** and a **published version**. They work independently — your team edits and tests the draft while leads only ever interact with the published version.

## Drafts

Any change you make in the Agent Editor — to the instructions, abilities, or configuration — is saved to the draft. Drafts are private. They do not affect live conversations until you explicitly publish.

To save changes to your draft, click **Save draft** in the editor header. You can save as often as you like. The draft persists between sessions, so you can make changes over multiple sittings before publishing.

**Testing always uses the draft.** The built-in [Testing](/agents/agent-overview/testing.md) interface and [Simulations](/agents/agent-overview/testing.md#simulations) always run against the current draft, so you can validate changes before going live.

## Publishing

When you're satisfied with your draft, click **Publish** in the editor header. Publishing makes the draft the new live version — all new conversations immediately use the updated agent.

Each agent has exactly one published version at a time. The previously published version is retained in Version History.

{% hint style="info" %}
**Chat agents** require at least one activation trigger on any non-default agent before publishing. If a non-default agent has no triggers, the publish button will show an error.
{% endhint %}

## Version History

Click **Version History** in the editor header to see a list of all previously published versions, newest first. Each entry shows who published it and when.

Select any version to preview its instructions. Click **Restore** to create a new draft from that version. Restoring does not publish — it gives you a draft to review and test before going live again.

## Unpublishing

To pause a live agent without deleting it, click **Unpublish**. Unpublished agents are not shown to leads. If the agent you're unpublishing is the default for its channel, Spara will prompt you to confirm — incoming traffic will have no agent to handle it until you publish a replacement.

## FAQ

### Do saved drafts affect live leads?

No. Saving a draft never affects live conversations. Only publishing changes what leads see.

### What happens if I publish and then notice a bug?

Open Version History, select the previous version, and click **Restore**. This creates a draft from the old version. Publish it to roll back immediately.

### Can multiple people edit the same draft?

Yes, but changes are not merged — the last save wins. Coordinate with your team to avoid overwriting each other's edits.
