# 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.

<Note>
  **Research Preview**: Blast radius is set as Research Preview and is under active development. Functionality and results may evolve as we continue to improve the feature. Research Preview features are not covered by any SLA. We recommend reviewing and validating outputs before use, and advise against relying on them in business-critical workflows.
</Note>

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

Qodo estimates risk by analyzing the change in the context of the codebase it affects, not just the size of the diff. It weighs the impact and intent behind the change: a one-line edit to a production database configuration can carry more risk than a large documentation update, and the classification reflects that difference.

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`.
