# Assess code change risk using blast radius

> Qodo automatically classifies the risk of a code change and can publish it as a native label in the pull request, helping teams triage which pull requests need the closest review.

Blast radius is Qodo's classification of a code change's risk, based on its scope and sensitivity. Qodo makes this classification available as a native pull request tag (Azure DevOps) or label (GitHub, GitLab), so you can triage which pull requests need the closest review directly from your Git provider's pull request list.

## How blast radius is classified

Each pull request receives one of three risk levels:

* 🔴 **Large blast radius**
* 🟠 **Medium blast radius**
* 🟡 **Small blast radius**

<Note>
  **Azure DevOps**: Native tags don't support displaying emoji in pull requests. As a result, the tag appears as plain text, for example "Large blast radius".
</Note>

The label reflects the highest risk level identified across the pull request's review cycle. If a later commit raises the risk, the label updates to match, but the pull request only ever shows one blast radius classification at a time.

## Set using the Qodo portal (Recommended)

<Steps>
  <Step>
    Navigate to **Configurations** > **Workflow** > **Code review**.
  </Step>

  <Step>
    Enable **Publish blast radius label**.
  </Step>
</Steps>

## Set using .pr\_agent.toml

```toml theme={null}
[review_agent]
publish_blast_radius_labels = true
```

Default: `false`.
