+sentryPythonDeleteTestFunctions
+===============================
+
+This AWS Lambda function deletes all AWS Lambda functions in the current AWS account that are prefixed with `test_`.
+The functions that are deleted are created by the Google Actions CI checks running on every PR of the `sentry-python` repository.
+
+The Lambda function has been deployed here:
+- AWS Account ID: `943013980633`
+- Region: `us-east-1`
+- Function ARN: `arn:aws:lambda:us-east-1:943013980633:function:sentryPythonDeleteTestFunctions`
+
+This function also emits Sentry Metrics and Sentry Crons checkins to the `sentry-python` project in the `Sentry SDKs` organisation on Sentry.io:
+https://sentry-sdks.sentry.io/projects/sentry-python/?project=5461230
