| :warning::rotating_light: Warning, this pull request increases the binary size of serverless extension by ${{ steps.compare.outputs.diff }} bytes. Each MB of binary size increase means about 10ms of additional cold start time, so this pull request would increase cold start time by ${{ steps.compare.outputs.coldstart }}ms. | |

| <summary>Debug info</summary> | |
| These dependencies were added to the serverless extension by this pull request: | |
| ``` | |
| ${{ steps.deps.outputs.deps }} | |
| ``` | |
| View dependency graphs for each added dependency in the [artifacts section](https://github.com/DataDog/datadog-agent/actions/runs/${{ github.run_id }}#artifacts) of the github action. | |
| We suggest you consider adding the `!serverless` build tag to remove any new dependencies not needed in the serverless extension. | |
