description: Protect production agents from accidental changes.
---------------------------------------------------------------

Once your agent is working well, lock it. Locking prevents accidental edits that could break a production agent.

**Location:** Top right → **Lock Agent** toggle

## How It Works

Toggle **Lock Agent** to ON — all editing becomes disabled.

**What's blocked:**

* Prompt editing
* Configuration changes
* Settings modifications
* Node changes (Convo Flow)

**What still works:**

* Test Agent
* View Conversation Logs
* Live calls continue normally

To make changes, toggle it back to OFF, edit, test, then re-lock.
