RISK

Why sf_create_lwc_jest_test is rated Medium

This tool creates and deploys new test files to Salesforce, which are reversible modifications to the codebase. It does not execute arbitrary code in production, delete data, move money, or perform irreversible actions. The blast radius is medium because incorrect test file deployments could interfere with CI/CD pipelines or mask real test failures, but the changes can be reverted.

From the tool's definition Tool description states 'Creates a Jest test file' and 'deployed via the Metadata API', indicating it creates new files and deploys them to Salesforce metadata.
