# On comment changed

> Start an automation when a Linear comment is created, updated, or removed.

`onLinearCommentChanged` watches all comment lifecycle actions in the workspace.

```ts automations/watch-linear-comments.automation.ts theme={null}
import { automation } from "automate.ax"
import { onLinearCommentChanged } from "automate.ax/linear"

export default automation("Watch Linear comments", () => {
  onLinearCommentChanged()
})
```

Optional static `account` defaults to the project binding. Returns a webhook signal with `type: "Comment"`, lifecycle `action`, provider-native `data`, optional `updatedFrom`, actor and URL, plus creation, workspace, and webhook metadata. Call `getComment` when the comment still exists and you need its normalized body and relationships.
